OpenAPI MCP Server
A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org.
- Demo: https://x.com/janwilmake/status/1903497808134496583

The MCP works by applying a 3 step process :
- It figures out the openapi identifier you need
- It requests a summary of that in simple language
- It determines which endpoints you need, and checks out how exactly they work (again, in simple language)
Important
OpenAPI MCP has found a new owner and has been migrated from v1.2 to v2, which works different to the previous version. You can still access any version prior to v2.0.0 and their README is here
OpenAPI MCP v2 is a Work In Progress and focuses on exploration and providing context about APIs. It does not allow executing the endpoints as tools directly, as authentication isn't a solved problem with MCP yet. However, it's great for codegen!

Features
- Get an overview of any OpenAPI specification
- Retrieve details about specific API operations
- Support for both JSON and YAML formats
- Tested with Claude Desktop and Cursor
Installation

Installing via npx
Run and follow instructions:
Usage in Claude
Once installed, you can ask Claude to:
- "Find information about the Stripe API"
- "Explain how to use the GitHub API's repository endpoints"
Claude will use the MCP server to:
- First get an overview of the requested API
- Then retrieve specific operation details as needed
Requirements
- Node.js >= 16.17.0
- Claude Desktop, Cursor, or any other MCP client.

This server cannot be installed
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
This tool creates a Model Context Protocol (MCP) server that acts as a proxy for any API that has an OpenAPI v3.1 specification. This allows you to use Claude Desktop to easily interact with both local and remote server APIs.
