{"answer":"Provide each connected app with one stable HTTPS Streamable HTTP endpoint, optionally on a provider-specific versioned URL path (e.g. /mcp/google/v1) while maintaining legacy routes for other clients. Google documentation recommends path-based versioning/provider-specific optimizations. Handle initialize, tools/list, tools/call over HTTP POST; for stateless MCP, HTTP 405 on optional GET is explicitly accepted. Include JSON as serialized TextContent: Google says structuredContent is not currently supported by its platform. Snapshot and test schemas/instructions before review; changes to published schemas require app versioning. Do not return system-instruction overrides in tool results.
