Connect Supabase to your AI assistants
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://registry.modelcontextprotocol.io/?q=com.supabase%2Fmcp)
Connect your Supabase projects to Cursor, Claude, Windsurf, and other AI assistants.
The Model Context Protocol (MCP) standardizes how Large Language Models (LLMs) talk to external services like Supabase. It connects AI assistants directly with your Supabase project and allows them to perform tasks like managing tables, fetching config, and querying data. See the full list of tools.
Setup
1. Follow our security best practices
Before setting up the MCP server, we recommend you read our security best practices to understand the risks of connecting an LLM to your Supabase projects and how to mitigate them.
2. Configure your MCP client
To configure the Supabase MCP server on your client, visit our setup documentation. You can also generate a custom MCP URL for your project by visiting the MCP connection tab in the Supabase dashboard.
Your MCP client will automatically prompt you to log in to Supabase during setup. Be sure to choose the organization that contains the project you wish to work with.
Most MCP clients require the following information:
{
"mcpServers": {
"supabase": {
"type": "http",
"url": "https://mcp.supabase.com/mcp"
}
}

Questions
What is the Supabase MCP server?
Connect Supabase to your AI assistants
What tools does Supabase expose?
2 in total: 2 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Supabase safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Supabase need?
It reads SUPABASE_ACCESS_TOKEN from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Supabase run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @supabase/mcp-utils at 0.8.0.
How current is this page?
The grade is for one exact copy of the source (f83bea8e4991), read on 2026-09-22. The repository is watched and re-audited when it changes.
