Use the Supabase MCP server to inspect database schemas, query project data and retrieve docs through a project-scoped connection.
Supabase MCP connects an assistant to Supabase project tools, including database exploration and documentation. It is useful for understanding tables before writing a query or investigating a project problem.
The hosted service uses https://mcp.supabase.com/mcp and supports OAuth sign-in. Add project_ref to select a project. Supabase also documents read_only=true and the features parameter for limiting the exposed tool groups. The example below starts with database and documentation access in read-only mode.
Ask which tables and columns relate to your question, then request a bounded query. Keep the SQL with the answer so the result can be reproduced. Migration tools belong to a separate change workflow; their presence does not mean a schema change is needed to answer a data question.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| list_tables | Inspect the project’s database tables. |
| execute_sql | Run SQL subject to the configured access mode. |
| search_docs | Search Supabase documentation. |
