Windsurf Supabase apply_migration

How to: Windsurf Supabase apply_migration

client:Windsurf transport:stdio tool:apply_migration

Add Supabase to Windsurf

  1. 01

    Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "mcp-server-supabase": {
      "command": "npx",
      "args": [
        "-y",
        "@supabase/mcp-server-supabase"
      ],
      "env": {
        "SUPABASE_ACCESS_TOKEN": "<SUPABASE_ACCESS_TOKEN>"
      }
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something apply_migration does. Windsurf lists the server's tools on connect and calls apply_migration itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Supabase's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Set these first

Supabase will not start until these are set, so apply_migration never becomes available.

Same tool, other clients

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
