# attestify-mcp > MCP server exposing Attestify OS agents — and [Attestify Trust](https://attestifyos.com/trust)'s no-wallet agent identity + signed evidence — as callable tools for Claude Desktop, Cursor, Windsurf, and any MCP-compatible host. Attestify OS is infrastructure for AI agents operating in financial, compliance, and regulated workflows. Every governed run delivers: routing → governance enforcement → budget check → SLA check → execution → output verification → immutable receipt → on-chain settlement evidence. **Live base URL:** `https://attestifyos.com` This package is a real [Model Context Protocol](https://modelcontextprotocol.io) stdio server — your MCP host spawns it as a subprocess and talks JSON-RPC to it directly. It is not a plain HTTP client library. ## Quick start Add to your MCP host's config (e.g. Claude Desktop's `claude_desktop_config.json`): ```json { "mcpServers": { "attestify": { "command": "npx", "args": ["-y", "attestify-mcp"], "env": { "ATTESTIFY_BASE_URL": "https://attestifyos.com", "ATTESTIFY_API_KEY": "", "TRUST_AGENT_ID": "", "TRUST_PRIVATE_KEY": "" } } } } ``` `ATTESTIFY_API_KEY` is a tenant API key issued via `POST /api/keys` — it's sent as the `X-API-Key` header on every run. Without one, runs are unauthenticated and subject to the plan/x402 limits that apply to anonymous callers. `TRUST_AGENT_ID` / `TRUST_PRIVATE_KEY` are optional and unlock two more tools — see [Attestify Trust](#attestify-trust) below. ## Tools ### `attestify_research` Runs a deep research query through the Attestify Research Agent (`researcher-v2`) via `POST /api/run`. Returns a structured briefing with executive summary, key findings, and caveats. Each call is metered at $0.023 USDC and logged to the Attestify evidence ledger. **Arguments:** | Field | Required | Description | |---|---|---| | `query` | Yes | The research question, topic, or subject to investigate. | | `url` | No | Optional source URL to include as context for the research run. | | `session_id` | No | Optional session ID for conversation continuity. | **Returns:** a JSON blob with `summary`, `loop_id`, `run_id`, `input_hash`, `output_hash`, `price_usdc`, `agent_id`, `receipt_url`, and `created_at`. ### `attestify_trust_submit_evidence` / `attestify_trust_verify` Available whenever `TRUST_AGENT_ID` and `TRUST_PRIVATE_KEY` are both set. A separate concern from `attestify_research` above — no x402, no lanes, no spend, no wallet at any point. `attestify_trust_submit_evidence` signs (Ed25519, via Node's built-in `node:crypto` — no extra dependency) and submits evidence that the agent completed real work, returning a signed, timestamped, publicly verifiable receipt. | Field | Required | Description | |---|---|---| | `summary` | Yes | Plain-language description of the work done. Gets signed and permanently recorded. | | `schema` | No | Evidence schema version. Default `work-completion/v1`. | | `action_basis` | No | `explicit` (default) or `discretionary`. | `attestify_trust_verify` independently re-verifies any receipt by ID — public, no API key needed, works for receipts from any agent. | Field | Required | Description | |---|---|---| | `receipt_id` | Yes | The receipt ID to verify. | **Getting `TRUST_AGENT_ID` / `TRUST_PRIVATE_KEY`:** run this once, outside of any MCP session — never generate a fresh identity per session, it would both break the agent's own verified-active streak and add noise to Attestify's public census instead of a real, citable number: ```bash npx attestify trust-init --name "My MCP Agent" ``` This registers a free Trust agent, generates its Ed25519 signing key locally, and prints the two values to set in your MCP host's config. The private key never leaves your machine except as a signature. ## Enterprise self-serve Issue a tenant key, set a budget, attach policies — every subsequent run through this server is auto-governed: ``` 1. POST /api/keys → issue tenant API key 2. POST /api/budgets → set USDC spend ceiling 3. POST /api/policies → attach governance rules 4. (this MCP server) → every run auto-enforced ``` ## Links - **Homepage:** https://attestifyos.com - **Attestify Trust:** https://attestifyos.com/trust - **Quickstart:** https://attestifyos.com/quickstart - **OpenAPI spec:** https://attestifyos.com/openapi.json - **x402 discovery:** https://attestifyos.com/.well-known/x402.json - **GitHub:** https://github.com/attestifyagent/attestify-mcp
