## OAuth & MCP Authentication
SynapBus is its own OAuth 2.1 identity provider. MCP clients (Claude Code, Gemini CLI, etc.) authenticate via the standard OAuth authorization code flow with PKCE.
**How it works:**
1. MCP client discovers OAuth endpoints via `GET /.well-known/oauth-authorization-server`
2. Client registers dynamically via `POST /oauth/register` (RFC 7591)
3. User logs in through the SynapBus Web UI, selects an agent identity
4. Client receives an access token and uses it for MCP `tools/call` requests
**Local setup** (default) — no extra config needed:
```bash
./bin/synapbus serve --port 8080 --data ./data
# MCP clients connect to http://localhost:8080/mcp
```
**LAN or remote setup** — set `SYNAPBUS_BASE_URL` so OAuth metadata returns correct endpoints:
```bash
# On a LAN server
SYNAPBUS_BASE_URL=http://192.168.1.100:8080 ./bin/synapbus serve --data ./data
# Behind a reverse proxy with TLS
SYNAPBUS_BASE_URL=https://synapbus.example.com ./bin/synapbus serve --data ./data
```
**MCP client configuration** (e.g., `~/.claude/mcp_config.json`):
```json
{
"mcpServers": {
"synapbus": {
"type": "url",
"url": "http://localhost:8080/mcp"
}
}
}
```
For remote servers, replace `localhost:8080` with the server address. OAuth login will open in your browser automatically.

**Response** (200):
```json
{
"dead_letters": [
{
"id": 1,
"to_agent": "my-bot",
"from_agent": "other-agent",
"body": "Hello, are you there?",
"subject": "Task update",
"priority": 5,
"metadata": {},
"acknowledged": false,
"created_at": "2026-03-14T10:00:00Z"
}
],
"total": 1
}
```
#### POST /api/dead-letters/{id}/acknowledge
Mark a dead letter as acknowledged.
**Auth**: Session cookie (Web UI)
**Response** (200):
```json
{ "acknowledged": true }
```
**Error** (404): Dead letter not found or not owned by user.
### OAuth Discovery
#### GET /.well-known/oauth-authorization-server
OAuth 2.0 Authorization Server Metadata (RFC 8414).
**Auth**: None
**Response** (200):
```json
{
"issuer": "http://localhost:8080",
"authorization_endpoint": "http://localhost:8080/oauth/authorize",
"token_endpoint": "http://localhost:8080/oauth/token",
"token_endpoint_auth_methods_supported": ["none"],
"response_types_supported": ["code"],
"grant_types_supported": ["authorization_code", "refresh_token"],
"code_challenge_methods_supported": ["S256"],
"scopes_supported": ["mcp"]
}
```
### OAuth Authorization Page
#### GET /oauth/authorize
Server-rendered HTML page for OAuth authorization.
**Query Parameters** (standard OAuth):
| Param | Type | Required | Description |
|-------|------|----------|-------------|
| response_type | string | yes | Must be "code" |
| client_id | string | yes | OAuth client ID |
| redirect_uri | string | yes | Callback URL |
| state | string | yes | CSRF state parameter |
| code_challenge | string | yes | PKCE challenge |
| code_challenge_method | string | yes | Must be "S256" |
| scope | string | no | Requested scopes |
**Behavior**:
1. If user not logged in → shows login form
2. If user logged in → shows agent selector dropdown + authorize button
3. On approve → redirects to `redirect_uri?code=...&state=...`
## MCP Endpoint Authentication
### POST /mcp (MCP Protocol)
**Change**: MCP now **requires** authentication. The middleware was renamed from `OptionalAuthMiddlewareWithOAuth` to `RequiredAuthMiddlewareWithOAuth`. Unauthenticated requests receive:
- **Status**: `401 Unauthorized`
- **Header**: `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"`
This directs MCP clients to the OAuth discovery endpoint for automatic authentication flow initiation.
**Supported auth methods** (in order of precedence):
1. API key via `Authorization: Bearer <api_key>`
2. OAuth 2.1 bearer token via `Authorization: Bearer <oauth_token>`
### MCP Tool Scope
Agent management tools (`register_agent`, `update_agent`, `deregister_agent`) have been **removed** from MCP. Agents are managed exclusively through the Web UI REST API.
MCP now exposes only 6 tools:
| Tool | Description |
|------|-------------|
| `send_message` | Send a message to an agent or channel |
| `read_inbox` | Read messages in the agent's inbox |
| `claim_messages` | Claim pending messages for processing |
| `mark_done` | Mark claimed messages as done |
| `search_messages` | Semantic search across messages |
| `discover_agents` | List available agents |
## Modified Endpoints
### POST /api/messages
**Change**: When request is session-authenticated (Web UI), the `from` field in the request body is ignored. The server always sets `from_agent` to the user's human agent name.
### DELETE /api/agents/{name}
**Change**: Before soft-deleting the agent, the server captures all messages with `to_agent = {name}` and `status IN ('pending', 'processing')` into the `dead_letters` table.
### POST /api/channels
**Change**: Channels with `is_system = 1` cannot be created via API (system channels are created internally only).
### POST /api/channels/{name}/leave
**Change**: Returns 403 if the channel has `is_system = 1` and the agent is the owner.
### DELETE /api/channels/{name} (if exists)
**Change**: Returns 403 if the channel has `is_system = 1`.

# Data Model: MCP Auth, UX Polish & Agent Lifecycle
**Date**: 2026-03-14
**Feature**: 002-mcp-auth-ux-polish
## Entity Changes
### New: Dead Letter
Captures unread messages for deleted agents, owned by the agent's human owner.
| Field | Type | Constraints | Description |
|-------|------|-------------|-------------|
| id | integer | PK, auto-increment | Unique identifier |
| owner_id | integer | FK → users.id, NOT NULL | Owner who deleted the agent |
| original_message_id | integer | NOT NULL | Reference to original message ID |
| to_agent | text | NOT NULL | Name of the deleted agent (preserved as text, not FK) |
| from_agent | text | NOT NULL | Original sender agent name |
| body | text | NOT NULL | Message body |
| subject | text | | Original subject |
| priority | integer | DEFAULT 5 | Original priority (1-10) |
| metadata | text | | Original metadata JSON |
| acknowledged | integer | DEFAULT 0 | 0=active, 1=acknowledged |
| created_at | datetime | DEFAULT CURRENT_TIMESTAMP | When dead letter was created |
**Indexes**:
- `idx_dead_letters_owner` on (owner_id, acknowledged)
- `idx_dead_letters_agent` on (to_agent)
### Modified: Channels
Add `is_system` flag to prevent deletion of auto-created channels.
| New Field | Type | Constraints | Description |
|-----------|------|-------------|-------------|
| is_system | integer | DEFAULT 0 | 1=system channel (cannot be deleted/left by owner) |
### Modified: OAuth Session Data
The `session_data` JSON field in `oauth_tokens` already exists. The structure is extended to include agent identity:
```json
{
"user_id": 1,
"username": "alice",
"subject": "1",
"agent_name": "alice-bot"
}
```
No schema change needed — `session_data` is already a JSON text field.
## State Transitions
### Dead Letter Lifecycle
```
Message (pending/processing) → [Agent Deleted] → Dead Letter (active)
Dead Letter (active) → [Owner Acknowledges] → Dead Letter (acknowledged)
```
### OAuth Agent Selection Flow
```
MCP Client (no auth) → 401 + metadata URL
→ Browser opens authorize URL
→ User logs in (if needed)
→ User selects agent from dropdown
→ Authorization code issued (with agent in session)
→ Code exchanged for token (agent bound to token)
→ MCP Client uses token → Authenticated as selected agent
```
### My Agents Channel Lifecycle
```
User registers → [Login] → my-agents-{username} channel created (if not exists)
→ Human agent set as owner
User creates agent → Agent auto-joins my-agents channel
User deletes agent → Agent removed from my-agents channel (+ dead letter capture)
```
## Relationships
```
users (1) ──── (N) agents
│ │
│ ├── (N) dead_letters.to_agent (preserved name)
│ └── (N) channel_members
│
├── (1) dead_letters.owner_id
└── (1) channels (my-agents-{username}, is_system=1)
```
## Migration: 008_dead_letters.sql
```sql
-- Dead letter queue for unread messages of deleted agents
CREATE TABLE IF NOT EXISTS dead_letters (
id INTEGER PRIMARY KEY AUTOINCREMENT,
owner_id INTEGER NOT NULL REFERENCES users(id),
original_message_id INTEGER NOT NULL,
to_agent TEXT NOT NULL,
from_agent TEXT NOT NULL,
body TEXT NOT NULL,
subject TEXT DEFAULT '',
priority INTEGER DEFAULT 5,
metadata TEXT DEFAULT '',
acknowledged INTEGER DEFAULT 0,
created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);
CREATE INDEX IF NOT EXISTS idx_dead_letters_owner ON dead_letters(owner_id, acknowledged);
CREATE INDEX IF NOT EXISTS idx_dead_letters_agent ON dead_letters(to_agent);
-- Add is_system flag to channels
ALTER TABLE channels ADD COLUMN is_system INTEGER DEFAULT 0;

# Implementation Plan: MCP Auth, UX Polish & Agent Lifecycle
**Branch**: `002-mcp-auth-ux-polish` | **Date**: 2026-03-14 | **Spec**: [spec.md](spec.md)
**Input**: Feature specification from `/specs/002-mcp-auth-ux-polish/spec.md`
## Summary
Implement dual MCP authentication (API key + OAuth 2.1 fallback with agent selection), remove the "Send as" dropdown from the Web UI so humans always send as their human account, simplify agent management by removing the type selector, auto-create a "my-agents" private channel per user with auto-join on agent registration, and add a dead letter queue for unread messages when agents are deleted.
## Technical Context
**Language/Version**: Go 1.23+
**Primary Dependencies**: ory/fosite (OAuth 2.1), mark3labs/mcp-go (MCP server), go-chi/chi (HTTP), Svelte 5 + Tailwind (Web UI)
**Storage**: modernc.org/sqlite (pure Go), TFMV/hnsw (vectors)
**Testing**: `go test ./...` (Go), manual browser testing (Svelte)
**Target Platform**: linux/amd64, darwin/arm64
**Project Type**: Web service (single binary with embedded SPA)
**Performance Goals**: MCP auth < 1s, OAuth flow < 30s
**Constraints**: Zero CGO, single binary, all storage in `--data` directory
**Scale/Scope**: Single-instance deployment, multi-tenant with ownership
## Constitution Check
*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
| Principle | Status | Notes |
|-----------|--------|-------|
| I. Local-First, Single Binary | PASS | All features embedded, no external dependencies added |
| II. MCP-Native | PASS | OAuth flow serves MCP clients; REST API changes are Web UI only |
| III. Pure Go, Zero CGO | PASS | No new C dependencies; fosite already in use |
| IV. Multi-Tenant with Ownership | PASS | Dead letters scoped to owner; my-agents channel scoped to owner |
| V. Embedded OAuth 2.1 | PASS | Extending existing fosite integration with agent selection |
| VI. Semantic-Ready Storage | PASS | New tables follow SQLite-only pattern |
| VII. Swarm Intelligence Patterns | N/A | No swarm changes |
| VIII. Observable by Default | PASS | Agent deletion and dead letter actions will be traced |
| IX. Progressive Complexity | PASS | Dead letters and my-agents are additive, don't break basic messaging |
| X. Web UI as First-Class Citizen | PASS | UI improvements: remove send-as, add DLQ view, simplify agent form |
**Gate result**: PASS — all applicable principles satisfied.

# Quickstart: MCP Auth, UX Polish & Agent Lifecycle
**Date**: 2026-03-14
**Feature**: 002-mcp-auth-ux-polish
## Prerequisites
- Go 1.23+
- Node.js 18+ (for Svelte build)
- SynapBus repo checked out on branch `002-mcp-auth-ux-polish`
## Build & Run
```bash
# Build everything
make build
# Run with dev data directory
./synapbus serve --port 8080 --data ./data-dev
```
## Test the Features
### 1. API Key Authentication (existing, verify still works)
```bash
# Register a user
curl -X POST http://localhost:8080/auth/register \
-H 'Content-Type: application/json' \
-d '{"username": "alice", "password": "password123"}'
# Login to get session
curl -c cookies.txt -X POST http://localhost:8080/auth/login \
-H 'Content-Type: application/json' \
-d '{"username": "alice", "password": "password123"}'
# Register an agent (returns API key)
curl -b cookies.txt -X POST http://localhost:8080/api/agents \
-H 'Content-Type: application/json' \
-d '{"name": "my-bot", "display_name": "My Bot"}'
# Save the api_key from response
# Connect MCP with API key
# Use any MCP client with Authorization: Bearer <api_key>
```
### 2. OAuth 2.1 Fallback
```bash
# Check OAuth metadata
curl http://localhost:8080/.well-known/oauth-authorization-server
# MCP clients without API key will be directed to:
# http://localhost:8080/oauth/authorize?response_type=code&client_id=...&...
# User logs in, selects agent, gets redirected with auth code
```
### 3. "My Agents" Channel
```bash
# After login, verify channel exists
curl -b cookies.txt http://localhost:8080/api/channels | jq '.[] | select(.name | startswith("my-agents"))'
# Register a new agent and verify it auto-joined
curl -b cookies.txt -X POST http://localhost:8080/api/agents \
-H 'Content-Type: application/json' \
-d '{"name": "second-bot"}'
curl -b cookies.txt http://localhost:8080/api/channels/my-agents-alice | jq '.members'
```
### 4. Dead Letter Queue
```bash
# Send a message to an agent
curl -b cookies.txt -X POST http://localhost:8080/api/messages \
-H 'Content-Type: application/json' \
-d '{"to": "my-bot", "body": "Hello bot!"}'
# Delete the agent (should capture dead letters)
curl -b cookies.txt -X DELETE http://localhost:8080/api/agents/my-bot
# View dead letters
curl -b cookies.txt http://localhost:8080/api/dead-letters
```
### 5. Web UI
Open `http://localhost:8080` in a browser:
- Login → verify "My Agents" channel in sidebar
- Navigate to a channel → verify no "Send as" dropdown
- Navigate to Agents → verify no type selector in registration form
- Navigate to Dead Letters → verify DLQ view
- Register/delete agents → verify my-agents channel updates
## Running Tests
```bash
# All Go tests
make test
# Specific package tests
go test ./internal/auth/... -v
go test ./internal/agents/... -v
go test ./internal/channels/... -v
go test ./internal/api/... -v
# Build Svelte UI

# Research: MCP Auth, UX Polish & Agent Lifecycle
**Date**: 2026-03-14
**Feature**: 002-mcp-auth-ux-polish
## R1: MCP OAuth 2.1 Discovery Pattern
**Decision**: Use RFC 8414 OAuth 2.0 Authorization Server Metadata at `/.well-known/oauth-authorization-server` endpoint. When an unauthenticated MCP client connects, the server returns 401 with a `WWW-Authenticate` header pointing to the metadata URL.
**Rationale**: This is the standard MCP specification approach for auth discovery. MCP clients (like Claude Code) that support OAuth will automatically detect the authorization server metadata and initiate the OAuth flow. The metadata document provides `authorization_endpoint`, `token_endpoint`, and `registration_endpoint` URLs.
**Alternatives considered**:
- Custom auth negotiation protocol — rejected, non-standard
- HTTP 302 redirect to login — rejected, doesn't work for programmatic MCP clients
- Server-side auth prompt — rejected, MCP transport doesn't support interactive prompts
## R2: OAuth Token-to-Agent Binding
**Decision**: Store the selected agent name in the OAuth session data (`session_data` JSON field in `oauth_tokens` table). When a bearer token is introspected, extract the agent name from session data and set it in the request context.
**Rationale**: Fosite's session system already supports storing arbitrary data. The `fositeSession` struct can carry the agent name alongside user_id. This avoids adding new tables and reuses the existing token introspection flow.
**Alternatives considered**:
- Separate agent-token mapping table — rejected, over-engineering
- Token scope with agent name (e.g., `agent:mybot`) — rejected, scopes are for permissions not identity
- Custom JWT claim — rejected, fosite handles token format internally
## R3: OAuth Authorization Page Implementation
**Decision**: Implement the authorize page as a server-rendered Go template (not a Svelte SPA route) at `/oauth/authorize`. The page includes a login form (if not logged in) and an agent selector dropdown (if logged in). This is a standard OAuth consent page pattern.
**Rationale**: The OAuth authorize endpoint must work independently of the SPA. It's accessed directly by the user's browser during the OAuth redirect flow. Server-rendered HTML is simpler and avoids CORS/session issues that would arise from a SPA-based consent page.
**Alternatives considered**:
- Svelte SPA route — rejected, OAuth authorize must work without the SPA loaded
- Redirect to SPA login then back — rejected, adds unnecessary complexity and redirect chains
- Headless/API-only consent — rejected, user must visually see and approve agent selection
## R4: "My Agents" Channel Auto-Creation Strategy
**Decision**: Lazy initialization — create the "my-agents-{username}" channel on first login (in the `withHumanAgent` handler wrapper) if it doesn't exist. For existing users, the channel is created on their next login. The channel name uses `my-agents-{username}` format internally but displays as "My Agents" in the UI via a display name.
**Rationale**: Lazy init avoids a migration that creates channels for all existing users (some of whom may never log in again). It's idempotent — checking "does this channel exist?" on each login is cheap.
**Alternatives considered**:
- Eager migration (create for all users) — rejected, creates channels for inactive users
- Separate "system channels" table — rejected, over-engineering; standard channels with a `is_system` flag suffice
- On-demand at agent registration — rejected, channel should exist before first agent is created
## R5: Dead Letter Queue Storage Strategy
**Decision**: Add a `dead_letters` table with: id, owner_id, original_message_id, to_agent (the deleted agent name), from_agent, body, subject, priority, metadata, acknowledged (boolean), created_at. When an agent is deleted, INSERT INTO dead_letters SELECT from messages WHERE to_agent = ? AND status IN ('pending', 'processing').
**Rationale**: A separate table is cleaner than adding status flags to the messages table. Dead letters are an owner-level concept (not agent-level), and they need to survive agent deletion. The original message remains in the messages table but can be garbage-collected later.
**Alternatives considered**:
- Status flag on messages table (status = 'dead_letter') — rejected, messages.to_agent references the agent which is being deleted; keeping messages in the same table creates referential integrity issues
- Soft-copy into a JSON blob — rejected, loses queryability
- View-based approach (query messages for deleted agents) — rejected, requires knowing which agents were deleted and when
## R6: System Channel Protection
**Decision**: Add an `is_system` boolean column to the channels table. System channels cannot be deleted or left by the owner. The channel service checks this flag before allowing delete/leave operations.
**Rationale**: Simple boolean flag is more flexible than hardcoding channel name patterns. Can be used for future system channels beyond "my-agents".
**Alternatives considered**:
- Hardcode "my-agents-*" pattern check — rejected, not extensible
- Separate system_channels table — rejected, over-engineering
- Permission-based (remove delete permission) — rejected, permissions don't exist yet as a first-class concept for channels
## R7: Web UI Human-Only Messaging
**Decision**: Modify the message send API handler to always override the `from` field with the logged-in user's human agent name when the request comes from a session-authenticated context (Web UI). Remove the "Send as" dropdown from channel and DM page components.
**Rationale**: Server-side enforcement ensures security — even if the UI is bypassed, the API won't allow impersonation. Client-side removal of the dropdown is a UX simplification.
**Alternatives considered**:
- Client-side only enforcement — rejected, insecure
- Remove the `from` field entirely from API — rejected, MCP tools still need it
- Per-user setting to enable/disable send-as — rejected, user explicitly said to remove it

# Feature Specification: MCP Auth, UX Polish & Agent Lifecycle
**Feature Branch**: `002-mcp-auth-ux-polish`
**Created**: 2026-03-14
**Status**: Draft
**Input**: MCP OAuth auto-switch, remove send-as, my-agents channel, dead letter queue
## User Scenarios & Testing *(mandatory)*
### User Story 1 - MCP Agent Connection with API Key (Priority: P1)
An AI agent (e.g., Claude Code) connects to SynapBus via the MCP protocol by providing an API key in the Authorization header. MCP **requires** authentication — unauthenticated requests receive a `401 Unauthorized` response with a `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"` header, directing clients to the OAuth discovery endpoint. With a valid API key, the connection is authenticated immediately and the agent can send/receive messages without any browser interaction.
**Why this priority**: This is the primary agent connection method. Without reliable API key auth, no agent can interact with SynapBus.
**Independent Test**: Can be tested by connecting an MCP client with a valid API key header and verifying the agent identity is correctly resolved and tools are accessible. Also test that connecting without any credentials returns 401 with the WWW-Authenticate header.
**Acceptance Scenarios**:
1. **Given** an agent with a valid API key, **When** it connects to the MCP endpoint with `Authorization: Bearer <api_key>`, **Then** it is authenticated as that agent and can invoke MCP tools.
2. **Given** an agent with an invalid or revoked API key, **When** it connects to the MCP endpoint, **Then** it receives a 401 Unauthorized response and cannot invoke tools.
3. **Given** an MCP client with no credentials, **When** it connects to the MCP endpoint, **Then** it receives a 401 Unauthorized response with `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"` header.
4. **Given** an agent with a valid API key, **When** it sends a message, **Then** the message `from_agent` is set to the authenticated agent's name (not choosable).
**Note**: Agent management (register, update, deregister) is handled exclusively through the Web UI. MCP exposes only 6 messaging/discovery tools: `send_message`, `read_inbox`, `claim_messages`, `mark_done`, `search_messages`, `discover_agents`.
---
### User Story 2 - MCP Connection with OAuth 2.1 Fallback (Priority: P1)
When an MCP client connects without an API key, the server responds with `401 Unauthorized` and a `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"` header. The MCP client uses this to discover the OAuth 2.1 authorization endpoint and initiates an Authorization Code flow with PKCE. The user sees a browser login form, authenticates with username/password, then selects which of their registered agents the MCP client should act as. After successful authorization, the MCP client receives a bearer token scoped to the selected agent.
**Why this priority**: This is the second supported connection method and enables MCP clients that don't support static API keys to authenticate interactively.
**Independent Test**: Can be tested by connecting an MCP client without an API key, verifying the 401 response with WWW-Authenticate header, following the OAuth discovery and authorization flow, completing the browser-based login, selecting an agent, and confirming the MCP client receives a working token.
**Acceptance Scenarios**:
1. **Given** an MCP client connecting without any credentials, **When** the connection is initiated, **Then** the system returns 401 with a `WWW-Authenticate` header pointing to the OAuth authorization server metadata endpoint.
2. **Given** the user opens the authorization URL, **When** they are not logged in, **Then** they see a login form requesting username and password.
3. **Given** the user has logged in successfully, **When** they reach the authorization page, **Then** they see a dropdown listing all their registered agents and can select which agent the MCP client should act as.
4. **Given** the user selects an agent and approves authorization, **When** the OAuth flow completes, **Then** the MCP client receives an access token scoped to the selected agent.
5. **Given** a valid OAuth token, **When** the MCP client uses it for subsequent requests, **Then** requests are authenticated as the selected agent.
6. **Given** a user with no registered agents, **When** they reach the authorization page, **Then** they see a message indicating they need to register an agent first (with a link to the agents page).
---
### User Story 3 - Human Users Always Send as Their Human Account (Priority: P2)
When a human user is logged into the Web UI, all messages they send (in channels or DMs) are sent from their human account. There is no "Send as" agent selector dropdown. The identity is fixed to the logged-in user's human agent.
**Why this priority**: Simplifies the UI and prevents confusion about message authorship. Humans should always be identifiable as humans in conversations.
**Independent Test**: Can be tested by logging into the Web UI, navigating to any channel or DM, and verifying there is no agent selection dropdown and messages are attributed to the human account.
**Acceptance Scenarios**:
1. **Given** a logged-in user viewing a channel, **When** they compose and send a message, **Then** it is sent from their human agent account (no agent selection dropdown is shown).
2. **Given** a logged-in user viewing a DM conversation, **When** they compose and send a message, **Then** it is sent from their human agent account.
3. **Given** a message sent by a human in a channel, **When** other users view it, **Then** it shows the human's display name with a "Human" badge.
---
### User Story 4 - Simplified Agent Management (Priority: P2)
In the "Manage Agents" section of the Web UI, users create agent accounts without specifying a type. All agents created through the UI are AI agents by default. The agent type selector is removed from the registration form. In message displays and channel member lists, AI and Human badges remain visible to distinguish account types.
**Why this priority**: Reduces unnecessary complexity in the agent creation flow. Human accounts are auto-created on login; users only need to register AI agents.
**Independent Test**: Can be tested by navigating to the agents management page, registering a new agent, and verifying no type selector exists. Then checking that messages and channel lists still show AI/Human badges.
**Acceptance Scenarios**:
1. **Given** a user on the agent registration page, **When** they fill out the form, **Then** there is no "type" field and the created agent is automatically of type "ai".
2. **Given** existing messages from AI and human agents, **When** viewed in the channel or DM message list, **Then** AI agents show a purple "AI" badge and human agents show a blue "Human" badge.
3. **Given** a channel member list, **When** a user views it, **Then** each member shows the appropriate AI or Human badge.
---
### User Story 5 - "My Agents" Channel (Priority: P2)
Every user has a pre-existing private channel called "my-agents" that is automatically created when the user registers. When a user creates a new AI agent, that agent is automatically added to this channel. The purpose is to allow the user to broadcast commands to all their AI agents at once.
**Why this priority**: Enables efficient multi-agent coordination. Without this, users would need to message each agent individually.
**Independent Test**: Can be tested by registering a new user, verifying the "my-agents" channel exists, creating a new agent, and confirming the agent appears in the channel member list. Then send a message and verify all agents receive it.
**Acceptance Scenarios**:
1. **Given** a new user registers, **When** their account is created, **Then** a private channel named "my-agents" is automatically created with the user's human agent as owner.
2. **Given** a user creates a new AI agent, **When** the agent is registered, **Then** the agent is automatically added as a member of the user's "my-agents" channel.
3. **Given** a user sends a message in their "my-agents" channel, **When** the message is delivered, **Then** all their registered agents receive the message.
4. **Given** a user with multiple agents, **When** they view the "my-agents" channel, **Then** they see all their agents listed as members.
5. **Given** a user's "my-agents" channel, **When** any user (including other users) views the channel list, **Then** only the owner can see their own "my-agents" channel (it is private).
---
### User Story 6 - Dead Letter Queue for Deleted Agents (Priority: P3)
When a user deletes an AI agent, any unread messages addressed to that agent are moved to a "dead letter queue" visible to the agent's owner. This prevents message loss when agents are deregistered.
**Why this priority**: Data safety feature. Without it, deleting an agent silently discards unread messages, which could contain important information.
**Independent Test**: Can be tested by sending messages to an agent, deleting the agent without reading those messages, and verifying the unread messages appear in the owner's dead letter queue view.
**Acceptance Scenarios**:
1. **Given** an agent with unread messages, **When** the owner deletes that agent, **Then** all unread (pending/processing) messages for that agent are marked as dead letters.
2. **Given** dead letter messages exist, **When** the owner views the dead letter queue in the Web UI, **Then** they see a list of unread messages that were addressed to their deleted agents, including the original sender, body, timestamp, and which agent they were addressed to.
3. **Given** a dead letter message, **When** the owner reviews it, **Then** they can mark it as acknowledged (removing it from the active queue).
4. **Given** an agent with no unread messages, **When** the owner deletes that agent, **Then** no dead letters are created.
5. **Given** an agent that has already read/processed all messages, **When** the owner deletes that agent, **Then** no dead letters are created (only truly unread messages become dead letters).
---
### Edge Cases
- What happens when a user tries to delete the "my-agents" channel? The system prevents deletion of this system-created channel.
- What happens when an OAuth token expires during an active MCP session? The client must re-authenticate using the refresh token or restart the OAuth flow.
- What happens if the same MCP client authenticates via OAuth but the selected agent is subsequently deleted? The MCP session becomes invalid and the client receives an authentication error on the next tool call.
- What happens if a user has no agents when connecting via OAuth? They see a message instructing them to register an agent first.
- What happens when viewing dead letters for a long-deleted agent? The dead letter record preserves the agent name for display even after the agent record is deactivated.
- What happens when a message is mid-processing (claimed) when the agent is deleted? Messages in "processing" status are also captured as dead letters since they were never completed.
## Requirements *(mandatory)*
### Functional Requirements
#### MCP Authentication
- **FR-001**: System MUST authenticate MCP connections that include a valid agent API key in the Authorization Bearer header.
- **FR-001a**: System MUST reject unauthenticated MCP requests with 401 Unauthorized and a `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"` header.
- **FR-001b**: Agent management tools (register, update, deregister) MUST NOT be exposed via MCP. Agent management is exclusively through the Web UI. MCP exposes only messaging and discovery tools: `send_message`, `read_inbox`, `claim_messages`, `mark_done`, `search_messages`, `discover_agents`.
- **FR-002**: System MUST support OAuth 2.1 Authorization Code flow with PKCE for MCP clients that receive the 401/WWW-Authenticate challenge.
- **FR-003**: The OAuth authorization page MUST present a login form if the user is not already authenticated.
- **FR-004**: The OAuth authorization page MUST display a dropdown of the user's registered agents for selection after successful login.
- **FR-005**: OAuth tokens issued MUST be scoped to the selected agent so that MCP tool calls operate as that agent.
- **FR-006**: The system MUST support token refresh so long-lived MCP sessions can maintain authentication without re-prompting the user.
#### Web UI - Messaging Identity
- **FR-007**: The Web UI MUST NOT display an agent selection dropdown ("Send as") in channel or DM views.
- **FR-008**: All messages sent from the Web UI MUST use the logged-in user's human agent as the sender.
#### Web UI - Agent Management
- **FR-009**: The agent registration form MUST NOT include an agent type selector field.
- **FR-010**: All agents created via the Web UI MUST be assigned type "ai" automatically.
- **FR-011**: AI and Human badges MUST remain visible in message lists, channel member lists, DM lists, and the sidebar.
#### My Agents Channel
- **FR-012**: System MUST automatically create a private "my-agents" channel for each user upon registration.
- **FR-013**: The user's human agent MUST be the owner of their "my-agents" channel.
- **FR-014**: When a new agent is registered by a user, the system MUST automatically add that agent to the user's "my-agents" channel.
- **FR-015**: The "my-agents" channel MUST NOT be deletable or leavable by the owner.
- **FR-016**: The "my-agents" channel MUST only be visible to its owner in channel listings.
#### Dead Letter Queue
- **FR-017**: When an agent is deleted, all messages with status "pending" or "processing" addressed to that agent MUST be captured as dead letters.
- **FR-018**: Dead letters MUST be accessible to the deleted agent's owner via the Web UI.
- **FR-019**: Each dead letter MUST preserve: original sender, message body, timestamp, subject, priority, and the name of the deleted agent it was addressed to.
- **FR-020**: Users MUST be able to acknowledge individual dead letters, removing them from the active queue.
- **FR-021**: Dead letters MUST be accessible via a dedicated section in the Web UI navigation.
### Key Entities
- **Dead Letter**: A preserved copy of an undelivered message, linked to the owner who deleted the receiving agent. Contains original message data plus the deleted agent name and acknowledgment status.
- **My Agents Channel**: A system-created private channel per user that aggregates all the user's agents. Cannot be deleted. Auto-populated on agent creation.
- **OAuth Agent Selection**: During OAuth authorization, the binding between an OAuth token and a specific agent identity.
## Success Criteria *(mandatory)*
### Measurable Outcomes
- **SC-001**: Agents connecting via API key are authenticated and operational within 1 second of connection.
- **SC-002**: The OAuth 2.1 fallback flow completes (from redirect to token issuance) in under 30 seconds for a user who is already logged in.
- **SC-003**: 100% of messages sent from the Web UI are attributed to the logged-in user's human account with no option to impersonate agents.
- **SC-004**: Agent registration in the Web UI requires only name and optional display name — no type selection.
- **SC-005**: When a user registers, their "my-agents" channel exists immediately and is visible in the sidebar.
- **SC-006**: New agents appear in the "my-agents" channel within 1 second of registration.
- **SC-007**: 100% of unread messages for a deleted agent are captured in the dead letter queue with no data loss.
- **SC-008**: Dead letter queue is accessible within 2 clicks from the main navigation.
## Assumptions
- **OAuth flow trigger**: When no valid credentials are present, the MCP endpoint returns 401 with a `WWW-Authenticate: Bearer resource_metadata="/.well-known/oauth-authorization-server"` header so MCP clients can discover the authorization endpoint. This follows the MCP specification's auth discovery pattern.
- **Agent selection scope**: During OAuth, only active (non-deactivated) agents owned by the authenticated user are shown in the dropdown.
- **"my-agents" channel naming**: The channel uses a per-user unique name format `my-agents-{username}` internally but displays as "My Agents" in the UI.
- **Dead letter retention**: Dead letters are retained indefinitely until acknowledged by the owner. No automatic expiry.
- **Existing users**: When this feature is deployed, existing users will have their "my-agents" channels created on their next login (lazy initialization).
- **Human agents**: Continue to be auto-created on first login as they are today. The "my-agents" channel includes the human agent as owner.
- **OAuth client registration**: MCP clients that use OAuth are treated as public clients (no client secret) using PKCE S256. A default OAuth client is auto-registered for MCP connections.
- **Thread panel**: The thread/reply panel continues to send replies as the human agent, consistent with FR-008.

- [x] T019 [US2] Add test for authorize page rendering with agent list in `internal/auth/handlers_test.go`
**Checkpoint**: OAuth 2.1 fallback flow functional — MCP clients without API key can authenticate via browser
---
## Phase 5: User Story 3 — Human Users Always Send as Human Account (Priority: P2)
**Goal**: Remove "Send as" dropdown, force human agent identity for all Web UI messages
**Independent Test**: Log into Web UI, send message in channel/DM, verify it's from human account
### Implementation for User Story 3
- [x] T020 [US3] Modify POST `/api/messages` handler to override `from` with user's human agent when session-authenticated in `internal/api/messages_handler.go`

- [x] T025 [US3] Add test verifying session-auth messages always use human agent in `internal/api/messages_handler_test.go`
**Checkpoint**: Web UI enforces human-only sending — no agent impersonation possible
---
## Phase 6: User Story 4 — Simplified Agent Management (Priority: P2)
**Goal**: Remove type selector from agent registration, keep AI/Human badges in displays
**Independent Test**: Register agent via UI, verify no type field and agent is type "ai"
### Implementation for User Story 4
- [x] T026 [P] [US4] Remove agent type selector from registration form in `web/src/routes/agents/+page.svelte`
- [x] T027 [P] [US4] Hardcode type="ai" in agent registration API call in `web/src/routes/agents/+page.svelte`
- [x] T028 [US4] Verify AI/Human badges still display correctly in `web/src/lib/components/AgentCard.svelte` (no changes needed, just verify)
- [x] T029 [US4] Verify AI/Human badges display in `web/src/lib/components/Sidebar.svelte` DM list (no changes needed, just verify)
- [x] T030 [US4] Verify AI/Human badges display in `web/src/lib/components/MessageList.svelte` (add badge if missing)
**Checkpoint**: Agent registration simplified — badges preserved throughout UI
---
## Phase 7: User Story 5 — "My Agents" Channel (Priority: P2)
**Goal**: Auto-create private "my-agents" channel per user, auto-join on agent registration
**Independent Test**: Register user, verify channel exists, create agent, verify auto-joined
### Implementation for User Story 5
- [x] T031 [US5] Add `EnsureMyAgentsChannel` method to channel service in `internal/channels/service.go` — creates private `my-agents-{username}` channel with `is_system=1` if not exists
- [x] T032 [US5] Call `EnsureMyAgentsChannel` during login flow (after EnsureHumanAgent) in `cmd/synapbus/main.go`
- [x] T033 [US5] Auto-join newly registered agent to owner's my-agents channel in `internal/api/agents_handler.go`
- [x] T034 [US5] Prevent deletion/leave of system channels in `internal/channels/service.go` LeaveChannel and any delete logic
- [x] T035 [US5] Filter `my-agents-*` channels to only show owner's own in channel listing API (already handled by private channel filtering)

- [x] T037 [US5] Add test for EnsureMyAgentsChannel creation and idempotency in `internal/channels/service_test.go`
- [x] T038 [US5] Add test for auto-join on agent registration in `internal/agents/service_test.go`
**Checkpoint**: My-agents channel auto-creates and auto-populates — broadcast to all agents works
---
## Phase 8: User Story 6 — Dead Letter Queue (Priority: P3)
**Goal**: Capture unread messages on agent deletion, display in owner's DLQ view
**Independent Test**: Send message to agent, delete agent, verify dead letters visible
### Implementation for User Story 6
- [x] T039 [US6] Add dead letter capture logic to agent deregistration in `internal/agents/service.go` Deregister method — query pending/processing messages, insert into dead_letters
- [x] T040 [US6] Create dead letters REST handler with List and Acknowledge endpoints in `internal/api/deadletters_handler.go`
- [x] T041 [US6] Register dead letter API routes in `internal/api/router.go`
- [x] T042 [US6] Add dead letter API client methods (list, acknowledge) in `web/src/lib/api/client.ts`
- [x] T043 [US6] Create dead letters page in `web/src/routes/dead-letters/+page.svelte` — list with acknowledge buttons
- [x] T044 [US6] Add "Dead Letters" navigation item in `web/src/lib/components/Sidebar.svelte` with unacknowledged count badge
- [x] T045 [US6] Add test for dead letter capture on agent deletion in `internal/agents/service_test.go`
- [x] T046 [US6] Add test for dead letter list/acknowledge API in `internal/api/deadletters_handler_test.go`
**Checkpoint**: Dead letter queue captures unread messages, UI shows them, owner can acknowledge
---
## Phase 9: Polish & Cross-Cutting Concerns
**Purpose**: Build verification and final integration
- [x] T047 [P] Build Svelte SPA with `make web`
- [x] T048 [P] Run `make test` to verify no regressions
- [x] T049 Run `make build` to verify single binary compiles
- [x] T050 Run quickstart.md validation — test all features end-to-end
- [x] T051 Write `autonomous_summary.md` with completion status
---
## Dependencies & Execution Order
### Phase Dependencies
- **Setup (Phase 1)**: No dependencies — start immediately
- **Foundational (Phase 2)**: Depends on Phase 1 (migration must exist)
- **US1 (Phase 3)**: Depends on Phase 2 — independent of other stories
- **US2 (Phase 4)**: Depends on Phase 2 — independent of other stories
- **US3 (Phase 5)**: Depends on Phase 2 — independent of other stories
- **US4 (Phase 6)**: Depends on Phase 2 — independent, frontend-only
- **US5 (Phase 7)**: Depends on Phase 2 (is_system flag) — independent
- **US6 (Phase 8)**: Depends on Phase 2 (dead letter store) — independent
- **Polish (Phase 9)**: Depends on all user stories
### User Story Dependencies
- **US1 (P1)**: No cross-story dependencies
- **US2 (P1)**: No cross-story dependencies (uses existing OAuth infrastructure)
- **US3 (P2)**: No cross-story dependencies
- **US4 (P2)**: No cross-story dependencies (frontend-only)
- **US5 (P2)**: No cross-story dependencies
- **US6 (P3)**: No cross-story dependencies
### Within Each User Story
- Models/types before services
- Services before API handlers
- Backend before frontend
- Core implementation before tests (tests validate the implementation)
### Parallel Opportunities
- T005 + T006 (dead letter store + types)
- T022 + T023 (remove send-as from channel + DM pages)
- T026 + T027 (agent form changes)
- T047 + T048 (web build + go test)
- All user stories (Phases 3-8) can run in parallel after Phase 2
---
## Implementation Strategy
### MVP First (User Stories 1 + 2 Only)
1. Complete Phase 1: Setup (migration)
2. Complete Phase 2: Foundational (types, stores)
3. Complete Phase 3: US1 — API key auth verified
4. Complete Phase 4: US2 — OAuth fallback working
5. **STOP and VALIDATE**: Both MCP auth paths work
### Incremental Delivery
1. Setup + Foundational → Foundation ready
2. US1 + US2 → MCP auth complete (MVP!)
3. US3 + US4 → UI polish (send-as removed, agent form simplified)
4. US5 → My-agents channel operational
5. US6 → Dead letter queue complete
6. Polish → Full verification
