API Gateway Remote MCP Server (Public Preview)

This skill converts new or existing REST APIs on Google Cloud API Gateway into remote Model Context Protocol (MCP) servers (POST https://{default_hostname}/mcp, Public Preview). By annotating an OpenAPI 3.x (3.0.x or 3.1.x) specification with x-google-api-management.mcp and x-google-mcp-tool, API Gateway translates MCP JSON-RPC 2.0 requests (initialize, notifications/initialized, tools/list, tools/call) into standard HTTP REST requests to your backend while enforcing existing authentication and quota policies.
