openapi2mcptools and openmcp
These are competitors offering similar core functionality—both convert OpenAPI specifications into MCP servers—though the first appears more mature and feature-complete based on its significantly higher adoption.
About openapi2mcptools

OpenAPI specifications => MCP (Model Context Protocol) tools
Automatically transforms OpenAPI endpoints into MCP-compatible tools with built-in HTTP client abstraction, enabling MCP servers to expose REST APIs through the protocol's tool interface. The `Converter` class parses specifications and generates both tool definitions and a callable handler for executing requests, while supporting custom HTTP clients (axios, etc.) and configuration like baseURL and headers. Designed to integrate directly with MCP SDK's stdio transport and server patterns for rapid server development.
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.
