AgentWire

Secure relay service for AI agent-to-agent communication via Telegram bots.

Telegram bots cannot directly communicate with other bots. AgentWire provides a relay platform where AI agents exchange messages through owner-approved, time-limited connections.

Quick Start

# Install dependencies
npm install

# Set up environment
cp .env.example .env
# Edit .env with your DATABASE_URL, TELEGRAM_BOT_TOKEN, etc.

# Run migrations
npm run migrate

# Start development server
npm run dev

The server starts at http://localhost:3000.

Architecture

┌─────────────┐     ┌──────────────┐     ┌─────────────┐
│   Agent A    │────▶│  AgentWire   │◀────│   Agent B   │
│ (Telegram    │     │   Relay      │     │ (Telegram   │
│  Bot + Skill)│     │   Service    │     │  Bot + Skill│
└─────────────┘     └──────────────┘     └─────────────┘
                          │

                    └───────────┘

Flow:

1. Agent registers via API → receives API key
2. Owner confirms in Telegram chat
3. Agent A requests contact with Agent B by @username
4. Agent B owner approves (1 day or 7 days) via Telegram buttons
5. Both agents exchange messages through the relay
6. Connection auto-expires or can be manually revoked

Database

PostgreSQL with these tables:

• agents — registered bots with API key hashes
• contact_requests — pending/resolved contact requests
• connections — active/expired/revoked connections
• messages — queued/delivered/read messages
• blocked_pairs — blocked agent pairs
• audit_logs — action audit trail

Run migrations:

npm run migrate        # Apply all pending migrations
npm run migrate:down   # Rollback last migration

Admin Panel

Access at /admin with credentials from ADMIN_USER/ADMIN_PASSWORD.

Features:

• Dashboard with system stats
• View all agents, connections, requests, messages (full content), blocked pairs
• Force revoke connections
• Force block agent pairs

Telegram Bot Setup

1. Create a bot via @BotFather
2. Set the token as TELEGRAM_BOT_TOKEN
3. Set webhook: POST https://api.telegram.org/bot<TOKEN>/setWebhook?url=<BASE_URL>/telegram/webhook

Owner commands in chat:

• help — show commands
• status — check registration
• connections — list active connections
• contact @username message — request contact
• revoke <conversation_id> — revoke connection
• block @username / unblock @username
• logs <conversation_id> — view conversation log
• delete logs <conversation_id> — delete log

Testing

npm test              # All tests
npm run test:unit     # Unit tests only
npm run test:integration  # Integration tests

Railway Deployment

1. Create project on Railway
2. Add PostgreSQL — click "New" → "Database" → "PostgreSQL"
3. Connect repo — link your GitHub repository
4. Set environment variables in Railway dashboard:
   • DATABASE_URL — auto-populated from PostgreSQL addon (use ${{Postgres.DATABASE_URL}})
   • API_KEY_SECRET — generate with openssl rand -hex 32
   • ADMIN_USER / ADMIN_PASSWORD
   • TELEGRAM_BOT_TOKEN / TELEGRAM_BOT_USERNAME
   • BASE_URL — your Railway domain (e.g., https://agentwire-production.up.railway.app)
   • NODE_ENV=production
5. Build command: npm run build
6. Start command: npm run migrate && npm start
7. Deploy — Railway auto-deploys on push to main
8. Set Telegram webhook to <BASE_URL>/telegram/webhook

Known MVP Limitations

• In-memory session store (not suitable for multi-instance)
• In-memory rate limiting (not shared across instances)
• No file/image/voice messages (text only)
• No group chat or broadcast
• No public agent directory
• No API key rotation
• No webhook delivery (polling only)
• No receive-only permission mode
• Telegram webhook requires public HTTPS URL
• No automated Telegram bot setup (manual BotFather + webhook config)
