Supabase MCP Server

A Model Context Protocol (MCP) server that enables AI tools to interact with Supabase databases. This server provides tools for reading, creating, updating, and deleting records in Supabase tables.

Features

Read rows from any Supabase table with filtering and column selection
Create single or multiple records in tables
Update records based on filter conditions
Delete records based on filter conditions
Comprehensive tool descriptions for AI model understanding
Type-safe request/response handling with Pydantic
Docker support for easy deployment

Prerequisites

Python 3.9+
Docker and Docker Compose
Supabase project with service role key
FastMCP-compatible AI IDE

Installation

Clone the repository:

git clone https://github.com/yourusername/supabase-mcp.git
cd supabase-mcp

Create a .env file with your Supabase credentials:

cp .env.example .env
# Edit .env with your Supabase credentials:
# SUPABASE_URL=your-project-url
# SUPABASE_KEY=your-service-role-key

Build and start the container:

# Build and start in detached mode
docker-compose up --build -d

# To view logs
docker-compose logs -f

# To stop the container
docker-compose down

The server will be available at http://localhost:8000.

Docker Management Commands

# Start the container
docker-compose up

# Start in detached mode (background)
docker-compose up -d

# Stop the container
docker-compose down

# View logs
docker-compose logs -f

# Rebuild the container
docker-compose up --build

# Check container status
docker-compose ps

# Restart the container
docker-compose restart

Troubleshooting Docker Issues

If the container fails to start:
# Check logs docker-compose logs -f # Check container status docker-compose ps # Remove and rebuild docker-compose down docker-compose up --build
If you get port conflicts:
# Stop any existing containers using port 8000 docker-compose down # Or modify the port in docker-compose.yml # ports: # - "8000:8000" # Change the first number to an available port
If environment variables aren't loading:
# Verify .env file exists and has correct values cat .env # Check environment variables in container docker-compose exec mcp-server env

Configuring MCP in Your AI IDE

General Configuration Steps

Open your AI IDE's settings/preferences
Navigate to the MCP or AI settings section
Add a new MCP server with the following configuration:

{
  "name": "Supabase MCP",
  "command": "docker-compose",
  "args": ["up"],
  "cwd": "/path/to/supabase-mcp"
}

IDE-Specific Instructions

Cursor

Open Settings (⌘, or Ctrl+,)
Go to "AI" section
Under "MCP Servers", click "Add Server"
Use the configuration above
Restart Cursor to apply changes

VS Code with AI Extensions

Open Command Palette (⌘⇧P or Ctrl+Shift+P)
Search for "MCP" or "AI Settings"
Add new MCP server configuration
Use the configuration above
Reload VS Code window

JetBrains IDEs with AI Plugins

Open Settings (⌘, or Ctrl+Alt+S)
Navigate to "Tools" → "AI" → "MCP Servers"
Click "+" to add new server
Use the configuration above
Restart IDE to apply changes

Verifying MCP Connection

Check your IDE's status bar for MCP server status
Look for a green indicator or "MCP Connected" message
Try using AI features that require database access
Check Docker logs for any connection issues:
docker-compose logs -f

Usage

Start the MCP server:

docker-compose up

Configure your AI tool to use the MCP server:

{
  "mcpServers": {
    "supabase": {
      "command": "docker-compose",
      "args": ["up"]
    }
  }
}

Available Tools

read_rows

Read rows from a Supabase table with optional filtering and column selection.

Example usage:

{
  "table_name": "users",
  "columns": ["id", "name"],
  "filters": { "age": { "gt": 18 } },
  "limit": 10
}

create_records

Create one or more records in a Supabase table.

Example usage:

{
  "table_name": "users",
  "records": [
    { "name": "John", "age": 30 },
    { "name": "Jane", "age": 25 }
  ]
}

update_records

Update records in a Supabase table based on filter conditions.

Example usage:

{
  "table_name": "users",
  "filters": { "status": "inactive" },
  "updates": { "status": "active" }
}

delete_records

Delete records from a Supabase table based on filter conditions.

Example usage:

{
  "table_name": "users",
  "filters": { "id": 1 }
}

Security Considerations

Always use the service role key in a secure environment
Never expose the service role key in client-side code
Use appropriate row-level security policies in Supabase
Consider implementing rate limiting for production use
