概览

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.

Key features of OpenAPI MCP Server

Converts OpenAPI endpoints into Claude‑usable tools automatically
Supports file uploads via multipart/form-data (local files only)
Works with any OpenAPI v3.1 compliant API
Provides CLI tool for testing endpoints programmatically
Offers programmatic API (OpenAPIToMCPConverter, HttpClient) for custom integrations

Use cases of OpenAPI MCP Server

Test local development APIs through conversational debugging
Quickly prototype integrations with third‑party APIs
Explore and learn new APIs by asking natural‑language questions
Automate file upload workflows (profile pictures, documents, batch uploads)

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.

What format are API responses expected to be?

Response handling is optimized for JSON and text responses; streaming responses are not yet implemented.
