feat(binding-mcp-openapi): implement mcp_openapi proxy binding#1715
Conversation
Implements the foundational mcp binding module with server kind handler, McpBeginEx IDL type, JSON schema patch, config adapters, and module-info. Closes #1668 https://claude.ai/code/session_0174raBeXFTgt98bp4DTyRDm
Adds the mcp_openapi proxy binding that accepts MCP tool/resource streams and routes them to OpenAPI-backed HTTP operations. Includes config adapters for options.specs (catalog references), options.tools (per-tool descriptions), routes.when (tool name / resource URI), and routes.with (api-id / operation-id). Also adds stub modules for binding-mcp-http and binding-mcp-http.spec, and adds pom.xml + mcp.idl to specs/binding-mcp.spec which were missing from the prior binding-mcp commit. https://claude.ai/code/session_0174raBeXFTgt98bp4DTyRDm
