How to connect Supabase MCP

Supabase is a remote server: nothing to install. Your client opens the Supabase sign-in the first time.

Tools

The tool list as the server returned it on the last check. Servers that need sign-in do not list tools without credentials.

    Tool changes

    A tool added or removed, or an argument or schema changed. Agents that call Supabase break on these changes without an error on the server side.

    • No tool changes seen in the last 90 days.

    Incidents

    • No incidents in the last 90 days.

    Questions

    Is the Supabase MCP server down right now?

    The status at the top of this page is the result of the last daily check. MCP Canary connects to https://mcp.supabase.com/mcp the way an AI agent does (Streamable HTTP, then legacy SSE), and lists its tools. A failure counts as down only after a second check 30 seconds later fails too.

    Why does it say "sign-in required"?

    The server answered 401 or 403: it runs and asks for credentials, as OAuth and API key servers do. That counts as up. The check never uses credentials, so the tools behind the sign-in are not listed. It does follow the sign-in chain (the 401 challenge, the protected resource metadata, and the login server) and shows the result under "Sign-in health": if that chain breaks, users cannot connect even though the server answers.

    How do I get alerted when Supabase MCP breaks?

    This page checks once a day. To watch it every minute, with a real tool call, assertions on the answer, and email or webhook alerts, set up your own monitor: install the canary CLI and ask your coding agent to monitor it. The 7-day trial needs no card.
