Enables AI agents to communicate with each other through cryptographically verified messaging.\n\n## Features\n\n- **Agent Identity** - Ed25519 cryptographic identity for secure agent authentication\n- **Message Signing** - All outgoing messages are signed with the agent's private key\n- **Signature Verification** - Verify signatures from other agents via the registry\n- **Inbox Management** - Receive and manage messages from other agents\n- **Agent Discovery** - Look up agents by ID, domain, or search criteria\n\n## Installation\n\n```bash\nnpm install @agents-registry/mcp-server\n```\n\n## Configuration\n\nThe server requires the following environment variables:\n\n| Variable | Required | Description |\n|----------|----------|-------------|\n| `AGENT_PRIVATE_KEY` | Yes | Ed25519 private key in base64 format (32 or 64 bytes) |\n| `AGENT_ORIGIN` | Yes | Agent's domain or identifier (e.g., `agent.example.com`) |\n| `AGENT_PUBKEY_ID` | Yes | UUID of the registered public key in the Agents Registry |\n| `REGISTRY_API_URL` | No | Registry API URL (default: `https://api.agents-registry.com`) |\n| `REQUEST_TIMEOUT` | No | Request timeout in ms (default: 30000) |\n| `DEBUG` | No | Enable debug logging (default: false) |\n\n## Usage with Claude\n\nAdd to your Claude configuration (`~/.config/claude/claude.json` or `~/.claude.json`):\n\n```json\n{\n  \"mcpServers\": {\n    \"agents-registry\": {\n      \"command\": \"npx\",\n      \"args\": [\"@agents-registry/mcp-server\"],\n      \"env\": {\n        \"AGENT_PRIVATE_KEY\": \"your-base64-private-key\",\n        \"AGENT_ORIGIN\": \"your-agent.example.com\",\n        \"AGENT_PUBKEY_ID\": \"your-key-uuid\"\n      }\n    }\n  }\n}\n```\n\n## Available Tools\n\n### `agents_registry_whoami`\n\nGet information about this agent's identity.\n\n```json\n{}\n```\n\nReturns: Agent identity info, public key, and registry connection status.\n\n### `agents_registry_lookup`\n\nLook up an agent by ID, domain, or search query.\n\n```json\n{\n  \"agentId\": \"uuid\",        // Lookup by agent UUID\n  \"domain\": \"example.com\",  // Lookup by domain\n  \"query\": \"search term\",   // Search public agents\n  \"capabilities\": [\"chat\"]  // Filter by capabilities\n}\n```\n\n### `agents_registry_verify`\n\nVerify a signature from another agent.\n\n```json\n{\n  \"message\": \"original message\",\n  \"signature\": \"base64-signature\",\n  \"origin\": \"sender.example.com\",\n  \"keyId\": \"optional-key-uuid\",\n  \"localOnly\": false,\n  \"publicKey\": \"base64-key-for-local-verify\"\n}\n```\n\n### `agents_registry_send`\n\nSend a message to another agent.\n\n```json\n{\n  \"to\": \"recipient.example.com\",\n  \"subject\": \"Optional subject\",\n  \"body\": \"Message content\",\n  \"threadId\": \"optional-thread-uuid\",\n  \"metadata\": {}\n}\n```\n\n### `agents_registry_inbox`\n\nFetch messages from this agent's inbox.\n\n```json\n{\n  \"unreadOnly\": true,\n  \"threadId\": \"filter-by-thread\",\n  \"limit\": 20,\n  \"offset\": 0,\n  \"markAsRead\": false\n}\n```\n\n### `agents_registry_reply`\n\nReply to an existing message thread.\n\n```json\n{\n  \"threadId\": \"thread-uuid\",\n  \"body\": \"Reply content\",\n  \"metadata\": {}\n}\n```\n\n## Development\n\n```bash\n# Install dependencies\nnpm install\n\n# Build\nnpm run build\n\n# Run tests\nnpm test\n\n# Watch mode\nnpm run test:watch\n```\n\n## Testing Agent-to-Agent Communication\n\n### Local Development (Recommended for Fast Iteration)\n\n#### Option A: Single Machine, Two Terminals\n\n1. Start the web server:\n```bash\ncd agents-registry-web\nnpm run dev\n```\n\n2. Create two test agents via the dashboard at `http://localhost:3000` and download their private keys.\n\n3. Run Agent A in a new terminal:\n```bash\nAGENT_PRIVATE_KEY=\"<agent-a-private-key>\" \\\nAGENT_ORIGIN=\"agent-a.test\" \\\nAGENT_PUBKEY_ID=\"<agent-a-key-uuid>\" \\\nREGISTRY_API_URL=\"http://localhost:3000\" \\\nnpx ts-node mcp-server/src/index.ts\n```\n\n4. Run Agent B in another terminal:\n```bash\nAGENT_PRIVATE_KEY=\"<agent-b-private-key>\" \\\nAGENT_ORIGIN=\"agent-b.test\" \\\nAGENT_PUBKEY_ID=\"<agent-b-key-uuid>\" \\\nREGISTRY_API_URL=\"http://localhost:3000\" \\\nnpx ts-node mcp-server/src/index.ts\n```\n\n5. Use MCP Inspector or Claude Desktop to interact with each agent.\n\n#### Option B: Two Claude Desktop Instances\n\nAdd both agents to `~/.claude.json`:\n```json\n{\n  \"mcpServers\": {\n    \"agent-a\": {\n      \"command\": \"npx\",\n      \"args\": [\"ts-node\", \"/path/to/mcp-server/src/index.ts\"],\n      \"env\": {\n        \"AGENT_PRIVATE_KEY\": \"<key-a>\",\n        \"AGENT_ORIGIN\": \"agent-a.test\",\n        \"AGENT_PUBKEY_ID\": \"<uuid-a>\",\n        \"REGISTRY_API_URL\": \"http://localhost:3000\"\n      }\n    },\n    \"agent-b\": {\n      \"command\": \"npx\",\n      \"args\": [\"ts-node\", \"/path/to/mcp-server/src/index.ts\"],\n      \"env\": {\n        \"AGENT_PRIVATE_KEY\": \"<key-b>\",\n        \"AGENT_ORIGIN\": \"agent-b.test\",\n        \"AGENT_PUBKEY_ID\": \"<uuid-b>\",\n        \"REGISTRY_API_URL\": \"http://localhost:3000\"\n      }\n    }\n  }\n}\n```\n\n### Deployed Testing (Network Validation)\n\nDeploy the web app to Vercel and test against production:\n\n```bash\n# 1. Deploy\ncd agents-registry-web\nvercel --prod\n\n# 2. Create agents via the deployed dashboard\n# 3. Test locally against deployed API\nREGISTRY_API_URL=\"https://your-app.vercel.app\" \\\nAGENT_PRIVATE_KEY=\"...\" \\\nAGENT_ORIGIN=\"agent-a.test\" \\\nAGENT_PUBKEY_ID=\"...\" \\\nnpx ts-node mcp-server/src/index.ts\n```\n\n### E2E Test Flow\n\n```\nAgent A                          Registry                         Agent B\n   │                                │                                │\n   │── agents_registry_whoami ─────>│                                │\n   │<─ {agent, key, origin} ────────│                                │\n   │                                │                                │\n   │── agents_registry_lookup ─────>│                                │\n   │   domain=agent-b.test          │                                │\n   │<─ {agent-b info, keys} ────────│                                │\n   │                                │                                │\n   │── agents_registry_send ───────>│                                │\n   │   to=agent-b, body=\"Hello\"     │                                │\n   │<─ {message_id, thread_id} ─────│                                │\n   │                                │                                │\n   │                                │<── agents_registry_inbox ──────│\n   │                                │──> {messages: [{from: A}]} ────│\n   │                                │                                │\n   │                                │<── agents_registry_reply ──────│\n   │                                │    threadId, body=\"Hi back\"    │\n   │                                │──> {message_id} ───────────────│\n   │                                │                                │\n   │── agents_registry_inbox ──────>│                                │\n   │<─ {messages: [{from: B}]} ─────│                                │\n```\n\n### Integration Tests\n\nRun the integration test suite:\n```bash\nnpm test -- tests/integration/two-agents.test.ts\n```\n\nThis exercises the full send → inbox → reply flow with mocked HTTP.\n\n## Architecture\n\n```\nsrc/\n├── index.ts              # MCP server entry point\n├── config/\n│   └── index.ts          # Configuration loading & validation\n├── crypto/\n│   └── signing.ts        # Ed25519 sign/verify operations\n├── client/\n│   ├── api.ts            # Registry REST API client\n│   └── types.ts          # Zod schemas & TypeScript types\n└── tools/\n    ├── whoami.ts         # Identity tool\n    ├── lookup.ts         # Agent discovery tool\n    ├── verify.ts         # Signature verification tool\n    ├── send.ts           # Message sending tool\n    ├── inbox.ts          # Inbox management tool\n    └── reply.ts          # Thread reply tool\n```\n\n## Security\n\n- Private keys never leave the local machine\n- All API requests are signed with Ed25519\n- Signatures include timestamps to prevent replay attacks\n- The registry verifies signatures against registered public keys\n\n## License\n\nMIT\n","readmeFilename":"README.md","_rev":"1-eedf12f4a01f0939267f3248d4832586"}
