App not in the registry? Build your own in 60 seconds.
DataFaucet works with any URL. No waiting for someone else to build a server.
The MCP server registry is a directory. It helps you discover existing servers that the community has built for services like GitHub, Slack, or PostgreSQL. You install them locally, configure auth, and run them alongside your AI client.
DataFaucet is a builder. It creates new MCP servers for any app, including ones no one has built a server for yet. Internal dashboards, niche SaaS tools, custom admin panels. You point it at a URL and get a hosted server back.
Most teams need both: registry servers for common tools (the GitHub server is excellent) and DataFaucet for everything else (the internal tools, the undocumented APIs, the apps too niche for anyone to build an open-source server for).
Most companies use 20-50 SaaS tools. The registry might cover 5-10 of them. The rest are internal tools, niche platforms, or services too small for anyone to build an open-source server. DataFaucet fills that gap.
Even when a registry server exists, it might not expose the exact endpoints you need. DataFaucet lets you capture precisely the operations that matter to your workflow.
They create demand. We create supply.
