Supabase MCP or plain Postgres MCP?

Supabase MCP understands projects, auth config, and hosted workflows. Plain Postgres is enough if you only need SQL against the connection string.

Prefer read-only or feature-limited tool groups in production projects. Full write access can drop tables from a bad prompt.

Query and manage Supabase

Tables, SQL, and project config from Cursor

Supabase sits between “Databases” and “Cloud Platforms.” You want project-aware tools (tables, SQL, config), not a generic Postgres URL alone.

Use the supabase-community Supabase MCP (catalog official) for the supported hosted MCP URL and project-scoped tools.

Third-party Supabase MCPs help for alternate auth or self-managed setups.

One server — supabase-community/supabase-mcp. Not a stack merge.
