Notes
- The MCP endpoint advertised in the MCP discovery documents (
/mcp) is not yet deployed — the discovery metadata describes the intended shape ahead of the live server. - WebMCP tools are also registered imperatively in-page via
navigator.modelContext.registerToolfor agents that support it. - Unknown paths under
/.well-known/,/agent/, and/mcpreturn structured JSON (RFC 9457 problem details), not an HTML error page.
