What is OpenAPI MCP Server?
An MCP server that translates OpenAPI specifications into tools that Claude AI can use to interact with APIs.
How to use OpenAPI MCP Server?
- Clone the repository. 2. Install dependencies using
npm install. 3. Place your OpenAPI YAML file in the project directory or specify its path via theOPENAPI_FILEenvironment variable. 4. Configure environment variables likeDEBUGandOPENAPI_FILEif needed. 5. Initialize the server with Claude Desktop usingnpm run initor start manually withnpm start.

FAQ from OpenAPI MCP Server
What is an OpenAPI specification?
What is an OpenAPI specification?
It's a standard format for describing APIs, allowing machines to understand their capabilities without human intervention.
What is MCP?
What is MCP?
Model Context Protocol, a protocol that allows AI models like Claude to interact with external tools and APIs.
How does the server handle authentication?
How does the server handle authentication?
The server handles authentication based on how it's defined in your OpenAPI specification. You may need to configure environment variables or other settings to provide API keys or other credentials.
Can I use this server with other AI models besides Claude?
Can I use this server with other AI models besides Claude?
This server is specifically designed for Claude AI, but the underlying principles could potentially be adapted for other models with similar tool-calling capabilities.
What happens if an API call fails?
What happens if an API call fails?
The server will return the error response from the API to Claude for analysis. Debug logging can be enabled to provide more detailed information about the error.
