What is the MCP Openapi Connector MCP Server?

MCP Server for OpenAPI-based APIs with built-in authentication management

The short version

A unified Model Context Protocol (MCP) server for connecting OpenAPI-based APIs with built-in authentication management. This project enables Claude Desktop, Cursor, and other MCP-compatible clients to interact with authenticated OpenAPI-based APIs without requiring separate proxy servers.

  • Single Process Architecture — No separate proxy server needed
  • Built-in OAuth2 Authentication — Automatic token management and refresh
  • OpenAPI Integration — Automatically generate MCP tools from OpenAPI/Swagger specifications
  • Extensible Tool System — Easy to add custom tools and resources
  • Error Handling — Automatic retry and authentication error recovery
  • Simple Configuration — Single configuration file for all settings
