Arlet makes Supabase's official MCP server available from the AI client you already use. Signing in completes the connection.

The AI can manage projects, run SQL and migrations, read logs and advisories, deploy Edge Functions and search the docs. Write tools are included, so keep tool-call confirmation enabled in your AI client when working against production projects. The available tools are those provided by Supabase's official server.
