Provides environment variable management for securely storing configuration settings like Supabase credentials needed by the MCP server.
Listed as a prerequisite for the MCP server implementation, indicating Git integration for version control of the server codebase.
Enables GitHub Copilot to interact with Supabase databases through the MCP server, providing database schema information and query assistance based on the connected Supabase instance.
Connects AI assistants like GitHub Copilot to Supabase databases, allowing them to understand database schemas, know about tables and relationships, assist with query writing, and provide context-aware suggestions related to the data model.
Supabase MCP Server Implementation Plan
This document outlines the plan for creating a Model Context Protocol (MCP) server that connects to Supabase, allowing AI assistants like GitHub Copilot to interact with your Supabase database.
Table of Contents
Overview
The Supabase MCP server will act as a bridge between AI assistants (like GitHub Copilot) and your Supabase database. This allows the AI to:
Understand your database schema
Know about tables and relationships
Assist with query writing
Provide context-aware suggestions related to your data model
Prerequisites
Node.js 18+ installed
npm or yarn package manager
Supabase project with admin API key
VS Code with Copilot/MCP support
Git
Implementation Steps
1. Create Server Package
2. Install Dependencies
3. Basic Server Structure
Create these files:
src/index.js
- Main entry pointsrc/supabase-client.js
- Supabase connection handlingsrc/schema-provider.js
- Database schema extractionsrc/query-handler.js
- Safe query execution.env.example
- Environment variable templateconfig.js
- Configuration management
4. Server Implementation Details
src/index.js
This file will initialize the MCP server and connect the components:
src/supabase-client.js
src/schema-provider.js
src/query-handler.js
config.js
.env.example
5. Supabase Database Functions
You'll need to create these stored procedures in Supabase:
get_schema_information()
- Returns database schemaget_table_information(table_name TEXT)
- Returns info about specific tableexecute_query(query_string TEXT, query_params JSONB)
- Safely executes queries
Server Architecture
Configuration
Add the Supabase MCP server to your VS Code settings.json
:
Security Considerations
API Key Management:
Use a scoped API key with minimum required permissions
Store API keys securely, never commit to version control
Consider using a key rotation strategy
Query Restrictions:
Default to SELECT-only for safety
Consider implementing a query allowlist approach
Add rate limiting to prevent abuse
Data Protection:
Avoid exposing PII or sensitive data
Implement row-level security in Supabase
Consider adding data masking for sensitive fields
Installation Guide
Local Development
Clone the repository
git clone https://github.com/yourusername/mcp-server-supabase.git cd mcp-server-supabaseInstall dependencies
npm installCreate

node src/index.js
VS Code Integration
Update your VS Code
settings.json
with the server configurationRestart VS Code
Verify the server is running in the VS Code MCP panel
Usage Examples
Once integrated, you can use the Supabase MCP server in various ways:
Schema exploration:
What tables do I have in my Supabase database?Table information:
What columns are in the users table?Query assistance:
Help me write a query to get all users who signed up in the last 7 days
Troubleshooting
Server won't start
Check your Node.js version (should be 18+)
Verify your Supabase credentials
Check for error logs in the terminal
Schema not loading
Verify your Supabase service key has necessary permissions
Check that the database functions are properly created
VS Code can't connect
Check that the server path in settings.json is correct
Restart VS Code after configuration changes
Verify the server process is running
This server cannot be installed
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
