Turn any API into tools your AI agent can call. No SDK, no backend code, no API docs required.
MCP (Model Context Protocol) is a standard that lets AI agents call external tools. Instead of copy-pasting data between apps, your AI can directly query APIs, create records, and fetch live data through MCP servers.
DataFaucet generates these servers automatically by watching real API traffic.
Enter a URL
Go to the homepage and type any web app URL (e.g., app.notion.so). Click “Launch Browser”.
Browse normally
A cloud browser opens inline. Navigate the app for 30-60 seconds. Click around, load pages, trigger the actions you want your AI to perform.
Capture endpoints
Click “Done - Capture Endpoints”. DataFaucet extracts every API call the web app made (XHR, Fetch, REST, GraphQL).
Review and deploy
Select which endpoints to include. Click “Deploy as Hosted MCP Server”. You get a URL + API key instantly.
Connect to your AI
Paste the config into Claude Desktop, Cursor, Windsurf, or any MCP-compatible client. Your AI can now call those API endpoints as tools.
If you already have cURL commands (from browser DevTools, Postman, or docs), switch to the “Paste cURL” tab and paste them directly. DataFaucet parses the method, URL, headers, and body automatically.
Claude Desktop
Settings → Developer → Edit Config → paste the JSON config → restart Claude.
Claude Code
Add to .mcp.json in your project root or ~/.claude/.mcp.json globally.
Cursor
Settings → MCP → Add Server → paste the URL and set the Authorization header.
Windsurf
Add config to ~/.codeium/windsurf/mcp_config.json.
What APIs work?
Any web app that makes HTTP requests. REST, GraphQL, internal APIs behind SSO. If you can browse it, we can capture it.
Is my data safe?
Browser sessions are ephemeral and destroyed after capture. Captured endpoints are stored encrypted. You control which headers are included.
Can I self-host?
Yes. Download the generated .zip and run it anywhere. The hosted version handles deployment and scaling for you.
How many servers can I create?
Free tier: 3 servers. Pro ($29/mo): unlimited servers, longer sessions, custom domains.
Free. No credit card required.
