MCP from OpenAPI

One of the most powerful features of MCPHero is the ability to function as an MCP from OpenAPI generator. If you have an existing REST API with an OpenAPI (Swagger) specification, you can turn it into a full-featured MCP server in seconds.

How it Works

MCPHero's AI can ingest OpenAPI specifications to understand your API's endpoints, parameters, and authentication requirements. It then functions as an Auto MCP generator, creating the necessary tools to expose those endpoints to AI clients.

Step-by-Step Guide

1. Provide the OpenAPI URL: In the Chat UI, simple provide the URL to your openapi.json or swagger.yaml file.
2. AI Analysis: Our MCP Generator analyzes the schema and proposes a set of MCP tools that map to your API endpoints.
3. Selection: Choose which endpoints you want to expose as tools.
4. Configuration: Provide any required API keys or base URLs.
5. Deployment: Deploy your new MCP server with one click.

Benefits of MCP from OpenAPI

• Speed: Go from an existing API to a live MCP server in minutes.
• Accuracy: Automatically generated tool definitions based on your exact API schema.
• Managed: No need to host the translation layer yourself; MCPHero handles it all.

Use Cases

• Internal Tools: Expose your internal company APIs to Cursor or Claude for faster development.
• Product Integrations: Allow users of your API to use it via their favorite AI assistants.
• Rapid Prototyping: Quickly test how your API performs as a set of AI tools.

By using MCPHero as your MCP Generator, you bridge the gap between traditional REST APIs and the new world of Model Context Protocol.
