Install Supabase MCP in Cursor

Cursor mcp.json

Paste this into ~/.cursor/mcp.json (global) or.cursor/mcp.json (this repo). Merge it with servers you already have. Primer: how Cursor loads MCP.

{
  "mcpServers": {
    "supabase": {
      "url": "https://mcp.supabase.com/mcp"
    }
  }
}

MCP endpoint: https://mcp.supabase.com/mcp. Source: Supabase MCP.

What it is

Supabase MCP talks to the platform: projects, database, advisors, logs. Cursor can generate types from the live schema rather than from a week-old dump in the repo.

The problem it solves

Agents love to CREATE TABLE. They are less good at noticing the table already exists with a different column name. This server is how they look first.

Install steps

1. Add the URL. mcpServers.supabase.url = https://mcp.supabase.com/mcp.
2. Sign in. Complete OAuth or paste the token Supabase's current docs require. Enable read-only if the dashboard offers it.
3. Inspect schema. Ask Cursor to list tables in the linked project and compare them to your generated types.

A prompt that uses it

List tables in this Supabase project and point out columns this code still treats as required that the schema marks nullable.

If it will not connect

Wrong org or missing project grant is the usual miss. Confirm https://mcp.supabase.com/mcp. Do not put the database password in mcp.json; the MCP uses the platform token, not the Postgres URI.
