Works with your AI tools

• Claude Desktop & Claude Code

  MCP

  MCP over stdio (faucet mcp) or HTTP with an API key.

• Cursor

  MCP

  Add Faucet to .cursor/mcp.json: stdio, or the /mcp URL plus an X-API-Key header.

• ChatGPT

  OpenAPI

  Create a Custom GPT Action from https://your-host/openapi.json with API-key auth.

• Base44

  MCP · REST

  Add https://your-host/mcp with an X-API-Key header as a custom MCP server, or call the REST API from your app.

• Replit

  MCP · REST

  Add Faucet as an MCP server (URL + X-API-Key header) or call /api/v1 from your Repl.

• Custom apps

  REST · OpenAPI

  Plain REST + OpenAPI 3.1. Generate a typed client in any language.

‘Works with’ means it connects through MCP or REST/OpenAPI. Faucet is independent and not affiliated with or endorsed by these companies.

• Give your AI agent a database

  Hand Claude, Cursor or your own agent a read-only key. It can list tables, read schemas and query data over MCP, and nothing else.

  MCP

• Backend for AI app builders

  Base44, Replit, Lovable and friends speak REST. Give them your /openapi.json URL and a scoped key, and your real data shows up in the app.

  OpenAPI

• Unlock that on-prem SQL Server

  That database behind the firewall? Run Faucet next to it and get a modern REST API without touching the schema or moving the data.

  Legacy DB

• Ship an MVP this weekend

  Design your tables, point Faucet at them, build the frontend. Filtering, pagination, auth and API docs are already done.

  REST

• Internal tools & dashboards

  Power admin panels, reports and scripts from one API, with a role per tool so each one sees only the tables it needs.

  RBAC

• Self-host anywhere

  Raspberry Pi to Kubernetes. One static binary for Linux, macOS and Windows on amd64 and arm64, or the Docker image.

  Self-hosted
