Agent interface / JSON-RPC

Give an agent a research desk.

Discover tools, call a mutating tool, and inspect the same response an MCP client receives. No hidden simulation layer.

Send a request to inspect the live tool manifest.
Agent contract

Initialize, list tools, then call a mutating tool. The in-page “Create through agent” button is a real POST to /api/mcp, not a simulation.
