MCP.Pizza Chef: coleam00

Four tools cover the basics of a table: reading rows, adding records, updating everything that matches a condition, and deleting the same way. Matching is exact-value only, so you cannot ask for orders above a certain amount or names containing a word. The paging mentioned in the README was never built either, though you can cap how many rows come back. Setup runs through Docker and needs your project's service key, which has full administrator power and ignores the access rules you set on your tables.

README

Supabase MCP Server

A Model Context Protocol (MCP) server that provides tools for interacting with a Supabase database. This server enables AI assistants to perform database operations through a standardized interface.

NOTE: This Supabase MCP server was created as a demonstration of my AI IDE coding workflow. It is still a work in progress which I will expand on in future videos on my channel.

Features

  • Read Table Rows: Query data from Supabase tables with optional filtering, pagination, and column selection
  • Create Table Records: Insert new records into Supabase tables
  • Update Table Records: Modify existing records in Supabase tables based on filters
  • Delete Table Records: Remove records from Supabase tables based on filters

Prerequisites

  • Docker or Docker Desktop
  • Supabase account and project

Installation

  1. Clone the repository:
    git clone https://github.com/coleam00/supabase-mcp.git
    cd supabase-mcp

Docker Setup

  1. Build the Docker image:
    docker build -t mcp/supabase .

Usage

Running as an MCP Server with Docker

The Supabase MCP server can be integrated with AI assistants using the Model Context Protocol.

  1. Include the below configuration in your MCP config (in Claude Desktop, Windsurf, etc.)

Be sure to build the container with the installation steps first!

{
  "mcpServers": {
    "supabase": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-e", "SUPABASE_URL", "-e", "SUPABASE_SERVICE_KEY", "mcp/supabase"],
      "env": {
        "SUPABASE_URL": "YOUR-SUPABASE-URL",
        "SUPABASE_SERVICE_KEY": "YOUR-SUPABASE-SERVICE-ROLE-KEY"
      }
    }
  }
}
  1. Replace YOUR-SUPABASE-URL and YOUR-SUPABASE-SERVICE-ROLE-KEY with your actual Supabase credentials.

  2. The AI assistant can now access the Supabase database through the MCP server using the provided tools.

Available Tools

Read Table Rows
read_table_rows(
    table_name: str,
    columns: Optional[List[str]] = None,
    filters: Optional[Dict[str, Any]] = None,
    limit: Optional[int] = None,
    offset: Optional[int] = None
)

Example:

# Read active users
read_table_rows(
    table_name="users",
    columns=["id", "name", "email"],
    filters={"is_active": True},
    limit=10,
    offset=0
)
Create Table Records
create_table_records(
    table_name: str,
    records: Union[Dict[str, Any], List[Dict[str, Any]]]
)

Example:

# Create a new user
create_table_records(
    table_name="users",
    records={
        "name": "John Doe",
        "email": "john@example.com",
        "is_active": True
    }
)
Update Table Records
update_table_records(
    table_name: str,
    updates: Dict[str, Any],
    filters: Dict[str, Any]
)

Example:

# Update user status
update_table_records(
    table_name="users",
    updates={"status": "premium"},
    filters={"is_active": True}
)
Delete Table Records
delete_table_records(
    table_name: str,
    filters: Dict[str, Any]
)

Example:

# Delete inactive users
delete_table_records(
    table_name="users",
    filters={"is_active": False}
)

Model Context Protocol Integration

The Supabase MCP server implements the Model Context Protocol, which allows AI assistants to interact with Supabase databases in a standardized way.

How It Works

  1. The MCP server exposes tools for database operations (read, create, update, delete)
  2. AI assistants connect to the MCP server using the stdio transport
  3. The AI assistant can invoke the tools to perform database operations
  4. The MCP server handles the communication with Supabase and returns the results

MCP Configuration

The example_mcp_config.json file shows how to configure an AI assistant to use the Supabase MCP server:

{
  "mcpServers": {
    "supabase": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-e", "SUPABASE_URL", "-e", "SUPABASE_SERVICE_KEY", "mcp/supabase"],
      "env": {
        "SUPABASE_URL": "YOUR-SUPABASE-URL",
        "SUPABASE_SERVICE_KEY": "YOUR-SUPABASE-SERVICE-ROLE-KEY"
      }
    }
  }
}

This configuration tells the AI assistant:

  • To use Docker to run the MCP server
  • To pass the Supabase credentials as environment variables
  • To use the mcp/supabase Docker image

Using with AI Assistants

AI assistants that support the Model Context Protocol can use this server to:

  1. Query data from Supabase tables
  2. Insert new records into tables
  3. Update existing records
  4. Delete records

The assistant will have access to the tools documented in the "Available Tools" section above.

Environment Variables

Variable Description
SUPABASE_URL URL of your Supabase project
SUPABASE_SERVICE_KEY Service role key for Supabase authentication

supabase-mcp FAQ

Can I use this to fix a wrong value across many rows at once?
Yes. The update tool changes every record matching the condition you give, and delete works the same way. Neither asks you to confirm first, so check your condition carefully.
Do I need a key?
Yes, and it is the sensitive one. It needs your Supabase project's service key, which has full administrator power and bypasses the access rules protecting your tables. Do not use it on a shared computer.
Can I filter by greater than, or by text containing a word?
No. Filters match exact values only, so ranges, partial text, and date comparisons are out. Pull a sorted batch of rows and narrow it in conversation instead.
Does it page through a large table?
No, despite what the README lists as a feature. You can limit how many rows come back, but there is no way to fetch the next page after that.
Which apps does it work in?
Claude Desktop and Windsurf have documented setup steps, plus any other app that supports MCP servers.
How hard is setup?
Harder than most. You download the project and build a Docker image yourself, then paste a config block holding your project address and service key.
Is this ready for real business use?
The author describes it as a work in progress built to demonstrate a coding workflow, and there have been no code changes since March 2025. Treat it as a starting point rather than a finished product.
