Api200

What is Api200?

Api200 is an open-source API integration platform and gateway that simplifies managing third-party APIs. It provides auto-generated code, documentation, authentication, caching, error handling, and full MCP (Model Context Protocol) server support, enabling developers to integrate APIs or run an MCP server in minutes.

How to use Api200?

To use the Api200 MCP server with Claude Desktop, open Developer settings, add a new custom tool with the command npx api200-mcp@latest and set the environment variable USER_KEY to your API key. Alternatively, self-host the platform using Docker and the provided setup script, then access the frontend at http://<hostname>:3000 and the API handler at http://<hostname>:8080.

Key features of Api200

• Automated authentication management and response caching.
• Automatic retries, mock responses, and response transformation.
• Fallback responses and custom headers for APIs.
• Schema watching to detect changes in API responses.
• Incident detection and endpoint monitoring with charts.
• In-browser Swagger integration and import from OpenAPI/Postman.

Use cases of Api200

• Quickly integrate third-party APIs with auto-generated client code and docs.
• Set up an MCP server to connect AI assistants like Claude to custom APIs.
• Monitor and debug API endpoints with comprehensive logging and incident alerts.
• Cache and transform API responses to optimize performance and consistency.
• Import existing Postman or OpenAPI collections to manage endpoints centrally.

FAQ from Api200

What is the Api200 MCP server and how does it differ from the full platform?

The Api200 MCP server is a lightweight component that exposes managed API endpoints as MCP tools for AI clients. It relies on the full platform for authentication, caching, and endpoint configuration.

What are the runtime dependencies for the Api200 server?

The MCP server requires Node.js to run the npx command. For self-hosting the full platform you also need Docker, Docker Compose, and npm.

Where does data from the Api200 server reside?

Data can be stored either in Api200’s cloud platform (at api200.co) or on your own infrastructure if you self-host using Docker with Redis and Supabase.

How is the MCP server invoked and authenticated?

The server runs via npx api200-mcp@latest. Authentication is handled through the USER_KEY environment variable, which must be set to your API key.

What transport does the Api200 MCP server use?

The MCP server uses the stdio transport, as it is configured as a command-line tool (npx) in the MCP client settings.
