MCP

Model Context Protocol

Connect AI clients (e.g. Claude Desktop) to this MCP server.

Endpoint: /mcp — API Docs

Authentication

Pass a token in the Authorization header with each request:

Authorization: Bearer YOUR_TOKEN

Two ways to obtain a token:

Personal Access Token (PAT) — create one at /token after logging in.
Signup / Login — the agent can call the signup or login tool to obtain a session token programmatically.

Playground

Pick a tool, fill in parameters, and run it.

Response

Raw JSON-RPC

Payments

Metered tools are pay-per-call. Two ways to pay:

x402 — agents pay per call in USDC on Base. Call a metered tool with no auth and you get an HTTP 402 whose body lists the price and pay-to address; pay and retry. No account needed.
Credits — log in with a token and calls draw from your credit balance instead.

Prices are shown per tool below.
