OpenAPI Transformer

The oas-to-mcp server transforms any OpenAPI specification into a Model Context Protocol server, enabling AI assistants to interact with REST APIs through a standardized interface. It dynamically generates tools from API endpoints, handling parameter mapping, authentication, and request/response formatting automatically. The implementation parses OpenAPI documents from URLs or local files, creates appropriate tool schemas based on endpoint parameters and request bodies, and manages the execution of API calls when tools are invoked. This bridge between OpenAPI and MCP makes any documented API instantly accessible to AI assistants without requiring custom integration code.
