Want to see it in action?
60 seconds from URL to working MCP server. No code.
mcp.run is a hosting platform for pre-built MCP servers. Developers write servers and deploy them to Cloudflare Workers. If someone has built a server for your tool and published it there, you get a fast hosted endpoint.
DataFaucet is a generator. Point it at any URL, browse the web UI naturally, and it creates an MCP server from the API calls your browser makes. No code to write, no catalog to search, no dependency on another developer having built what you need.
They complement each other. Use mcp.run when a polished server exists. Use DataFaucet when it does not, or when you need to capture from internal or private applications.
