  "note": "This is a static discovery pointer, kept in sync by hand — not build-time generated from the live server. GET https://a2uicatalog.ai/mcp with a JSON-RPC tools/list call returns the live, authoritative tool list (including identify_model and render_ping, omitted above as internal/diagnostic). This describes an MCP server, not an A2A-protocol agent: supportedInterfaces.protocolBinding names the wire format (JSON-RPC over HTTP) honestly, not a claim of A2A JSON-RPC method conformance."
