About openmcp
getdatanaut/openmcp
Turn any openapi file into an mcp server, with just the tools you need.
Supports both OpenAPI-to-MCP conversion and stdio-based MCP server composition, allowing selective tool exposure through an `openmcp.json` config file. Implements stdio and SSE transports with direct integration into major chat clients (Cursor, Claude) via automated client configuration. Handles authentication management across multiple servers and enables mixing heterogeneous MCP sources—OpenAPI specs, stdio servers, and others—into a single unified MCP endpoint.
About mcp-openapi
ReAPI-com/mcp-openapi
OpenAPI specification MCP server.
Loads and dereferences multiple OpenAPI specifications from a directory, exposing API operations and schemas through MCP tools for LLM-powered IDE integration in Cursor. Implements a catalog-based architecture with search and lookup capabilities across specifications, using custom `x-spec-id` fields to disambiguate overlapping endpoints and schemas between services. Integrates directly into Cursor via `.cursor/mcp.json` configuration and provides tools for dynamic catalog refresh and semantic operation/schema discovery.
