What is OpenAPI to MCP Server?
The OpenAPI to MCP Server provides a bridge that converts OpenAPI specifications into MCP tools. It exposes REST API endpoints, supporting various HTTP methods, parameters, headers, and authentication mechanisms such as Bearer tokens, Basic Auth, and API keys. The server can be configured with different OpenAPI files and base URLs, and it works with MCP inspector and other MCP clients. Users can easily start the server via command line, linking their APIs to MCP ecosystems, enabling LLMs to perform API operations programmatically. It also supports customizing headers, enabling authentication, and integrating into different application frameworks with environment variables and configuration options for flexible deployments.
