Want tools that work everywhere?
Create MCP servers from any app. Works with Claude, Cursor, Codex, Copilot, and more.
ChatGPT Actions (formerly Plugins) let you connect external APIs to custom GPTs. You write an OpenAPI spec, configure authentication, and ChatGPT can call your endpoints. The result only works inside ChatGPT.
If you switch to Claude, Cursor, Windsurf, or any other AI tool, you start over. Your Actions are trapped in a single vendor.
MCP (Model Context Protocol) is an open standard. A server you create with DataFaucet works with any client that supports MCP. Build once, connect everywhere.
They create demand. We create supply.
Pick any URL. Browse for 30 seconds. Get a hosted MCP endpoint your AI can call immediately.
No credit card. No code. Free tier includes 3 servers.
