概要

What is OpenAPI MCP Server?

OpenAPI MCP Server is an MCP proxy that converts any OpenAPI v3.1 compliant API into tools usable by Claude Desktop or other MCP clients. It allows developers to interact with local and remote APIs through natural language, discovering endpoints, understanding parameters, and making API calls automatically.

How to use OpenAPI MCP Server?

Configure Claude Desktop by adding the MCP server entry in claude_desktop_config.json with the command npx openapi-mcp-server /absolute/path/to/openapi.json. Restart Claude Desktop, then start asking natural-language questions about your API.

FAQ from OpenAPI MCP Server

Which OpenAPI versions are supported?

Only OpenAPI v3.1 specifications are currently supported.

Are remote file URLs supported for uploads?

No, only local file paths are supported; remote URLs are not handled.

What are the security considerations for file uploads?

File paths resolve relative to the current working directory. Access is restricted to files the user can read, and sensitive files like SSH keys require explicit user confirmation. File contents are read only when making the actual API request.

How does the server handle large files?

Large files are streamed directly from disk to the API, with memory usage optimized and progress reporting available. Maximum file size is determined by the target API.
