MCP Supabase Server

The MCP Supabase Server wraps the Supabase Management API and project-scoped Postgres so an LLM client can run SQL, inspect tables, manage Auth users, and read Storage bucket metadata. Supabase itself publishes a first-party MCP server, and several community variants extend it with extra tools.

Frequently asked questions

Is this server official?

Yes — Supabase ships @supabase/mcp-server-supabase as an official implementation. Community forks extend it with extra tools.

Does it use the service role?

No — it uses a personal access token scoped to your Supabase account. Project data access still obeys RLS unless you explicitly enable a service-role mode.

Can Claude run arbitrary SQL?

Yes with run_sql. Point it at a read-only Postgres role and enable Supabase's Query logs to audit what the model runs.
