Overview

Supabase MCP Server is a tool that enables users to execute SQL queries, manage databases, access the Supabase Management API, and handle user authentication with built-in safety controls.

To use the Supabase MCP Server, install it via a package manager like pipx or uv, configure it with your Supabase project details, and connect it to your preferred MCP client such as Cursor or Windsurf.

  • Compatibility with various MCP clients supporting stdio protocol. - Control over read-only and read-write modes of SQL query execution. - Runtime SQL query validation with risk level assessment. - Robust transaction handling and automatic versioning of database schema changes. - Management of Supabase projects and users through the Supabase Management API.
  1. Executing complex SQL queries safely in a development environment.
  2. Managing user authentication and roles in Supabase projects.
  3. Automating database schema migrations and versioning.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "supabase-mcp-server-emanuelsistemas": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-supabase-mcp-server-emanuelsistemas"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "supabase-mcp-server-emanuelsistemas": {
