MCP server

An MCP server exposes tools over the Model Context Protocol so an AI agent can discover and call them without bespoke integration code.

In detail

Ours runs JSON-RPC 2.0 over HTTP and publishes five tools; the handshake and the tool list are open, while calling a tool needs the API key in the Authorization header. Reading and spending are deliberately separate tools, so a scoped key still constrains what an agent can do with them. Give the agent numbers:read and numbers:write, set an expiry, and leave the rental scopes off unless it genuinely needs them.
