What is OpenAPI MCP Server?

The OpenAPI MCP Server is a skeleton project designed to help developers quickly create their own MCP (Managed Component Protocol) server. It offers a foundation with implemented handlers across standard I/O, SSE, and OpenAPI/REST protocols, providing flexibility in communication methods.

How to use OpenAPI MCP Server?

The server can be built and run using Docker or Docker Compose. Configuration is managed through an mcp.json file. The MODE environment variable controls the server's operating mode (stdio, sse, or openapi). Refer to the README for specific commands to build and run the server in each mode.

Key features of OpenAPI MCP Server

  • Standard I/O (stdio) support

  • Server-Sent Events (SSE) support

  • OpenAPI/REST endpoints

  • Docker Compose integration

  • Configurable via mcp.json

  • Multiple running modes

Use cases of OpenAPI MCP Server

  • Building a new MCP server

  • Implementing handlers across multiple protocols

  • Experimenting with different communication methods (stdio, SSE, OpenAPI)

  • Integrating with existing systems using MCP

  • Creating a microservice that communicates via MCP
