supabase-mcp-server MCP Server: Complete Setup Guide

Last Updated: October 05, 2026

🤖 AI Snapshot / TL;DR: The supabase-mcp-server is a production-ready, open-source Model Context Protocol (MCP) server that enables AI agents (like Claude Desktop, Cursor, and Claude Code) to securely interact with api systems. It features local execution, standardized tool definitions, and is actively maintained with ⭐ 830 GitHub stars.

🔍 What is supabase-mcp-server?

Query mcp enables end-to-end management of supabase via chat interface: read & write query executions, management api support, automatic migration versioning, access to logs and much more.. By bridging the gap between large language models and your local or remote api environment, it allows you to automate complex workflows using natural language prompts. Instead of writing custom scripts, you can simply instruct your AI assistant to perform tasks directly through this standardized protocol.

✨ Key Features

• 💻 compatible with cursor, windsurf, cline and other mcp clients supporting stdio protocol
• 🔐 control read-only and read-write modes of sql query execution
• 🔍 runtime sql query validation with risk level assessment
• 🛡️ three-tier safety system for sql operations: safe, write, and destructive
• 🔄 robust transaction handling for both direct and pooled database connections

🎯 Real-World Use Cases for supabase-mcp-server

• Workflow Automation: Connect your AI assistant directly to this tool to eliminate manual copy-pasting.
• Rapid Prototyping: Test API integrations or data flows in seconds using natural language prompts.
• Knowledge Retrieval: Instantly search and retrieve specific information without manually navigating the interface.

⚙️ Installation & Configuration

Prerequisites

• Node.js (v18+) or Python (v3.10+) installed locally.
• Claude Desktop, Cursor, or another MCP-compatible client.

Step 1: Install the Server

```bash

Recommended: Run directly via npx (no global install needed)

npx -y alexander-zuev/supabase-mcp-server

Alternative: Clone and run locally

git clone https://github.com/alexander-zuev/supabase-mcp-server.git cd supabase-mcp-server npm install # or pip install -r requirements.txt ```

Step 2: Update Your MCP Config

Add the following to your claude_desktop_config.json (Mac: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\) or .cursor/mcp.json:

```json { "mcpServers": { "supabase-mcp-server": { "command": "npx", "args": ["-y", "alexander-zuev/supabase-mcp-server"] } } } ``` (Note: Restart your AI client after saving the configuration file.)

⚙️ Advanced Configuration Options

For production environments, you may need to customize the server behavior. You can pass environment variables in your MCP config:

```json { "mcpServers": { "supabase-mcp-server": { "command": "npx", "args": ["-y", "alexander-zuev/supabase-mcp-server"], "env": { "API_KEY": "your_api_key_here", "TIMEOUT_MS": "30000" } } } } ``` Note: Always use environment variables for sensitive credentials. Never hardcode API keys directly in the JSON.

💡 Real-World Example Prompts

Once connected, try these high-value prompts in Claude or Cursor:

1. "Use supabase-mcp-server to extract structured data or automate a specific api workflow."
2. "Configure the supabase-mcp-server MCP server to optimize for speed and reliability."
3. "Analyze the output from supabase-mcp-server and format it into a comprehensive Markdown report."
