        Doc-only schema for the standard MCP `ApiResponse` envelope
        (`{"data": …, "status_code": N, "message": "…"}`). Most `/api/mcp/*`
        payloads are service-layer `serde_json::Value` views, so `data` is
        documented as a free-form object; each route's response description says
        what it carries.
