About

OpenAPI Proxy is a Python package that bridges the gap between REST APIs described by OpenAPI specifications and Model Context Protocol (MCP) ecosystems. It dynamically creates MCP tools from OpenAPI endpoints, enabling users to invoke REST APIs as tools within MCP-based workflows. With support for both low-level (dynamic tool registration) and FastMCP (simplified, static configuration) modes, OpenAPI Proxy offers flexibility and ease of integration for a variety of API-driven applications.

Key Features

  • Dynamic tool generation from OpenAPI specifications
  • Simple mode (FastMCP) for static configurations
  • OpenAPI v3 compatibility (potential v2 support)
  • Endpoint filtering via whitelisting
  • Customizable payload authentication via JMESPath

Use Cases

  • Integrating third-party APIs into MCP workflows
  • Automating API interactions within a model context
  • Creating custom tools for managing cloud resources
