Ask for something preflight_x402_endpoint does. Cline lists the server's tools on connect and calls preflight_x402_endpoint itself — you do not invoke it by name.

If nothing happens, check the server is running and that ProofCheck's identifier in your config matches the one above exactly.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 5 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
