The OpenAPI MCP Server exposes REST APIs defined by OpenAPI specifications as MCP tools, allowing Large Language Models to discover and interact with those endpoints through the Model Context Protocol. It provides both CLI and library interfaces with support for stdio and HTTP transport methods, along with optional MCP prompts and resources capabilities. The server solves the problem of bridging the gap between LLMs and REST APIs by automatically converting OpenAPI definitions into callable MCP tools with authentication support.
