This JavaScript-based server seamlessly converts OpenAPI 3.x specifications into a set of Model Context Protocol (MCP) tools, allowing Large Language Models (LLMs) to effortlessly interact with RESTful APIs. It automates the generation of MCP tools from your API definitions, handling parameter mapping, authentication (including Bearer tokens), and robust error handling. The server offers both stdio and HTTP transport options, a command-line interface for easy configuration and validation, and ensures LLMs can leverage existing API ecosystems through a standardized protocol.
