Use the Supabase MCP server
in Claude

Query your database, inspect schema, and manage projects (dev, not prod). This guide connects Supabase to Claude (claude.ai and the Claude desktop app) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Setup: Supabase in Claude

Claude adds MCP servers via custom connectors in Settings. The gateway route takes about two minutes:

  1. Create a free gate gateway and connect Supabase to it from the verified directory (one click).
  2. Open claude.ai → Settings → Connectors and click 'Add custom connector'.
  3. Name it 'gate' and paste your gateway URL, then approve the authorization.
  4. Ask Claude something Supabase can answer — the call runs through your gateway, with your rules applied and logged.

What to ask once it’s connected

“Show me the schema of the users table.”
“Query signups per week in the dev database.”
“Why might this query be slow? Check the indexes.”
“Draft a migration for this new column.”

Why route it through a gateway

One URL, every client

The same Supabase connection works in Claude Code, ChatGPT, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool Supabase exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything Claude did with Supabase — searchable, exportable, auditable.

Scanned and probed

Supabase passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
