Supabase MCP Server

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"
    }
  }
}

If you don't see your MCP client listed in our documentation, check your client's MCP documentation and copy the above MCP information into their expected format (json, yaml, etc).

CLI

If you're running Supabase locally with Supabase CLI, you can access the MCP server at http://localhost:54321/mcp. Currently, the MCP Server in CLI environments offers a limited subset of tools and no OAuth 2.1.

Self-hosted

For self-hosted Supabase, check the Enabling MCP server page. Currently, the MCP Server in self-hosted environments offers a limited subset of tools and no OAuth 2.1.

Options

The following options are configurable as URL query parameters:

• read_only: Used to restrict the server to read-only queries and tools. Recommended by default. See read-only mode.
• project_ref: Used to scope the server to a specific project. Recommended by default. If you omit this, the server will have access to all projects in your Supabase account. See project scoped mode.
• features: Used to specify which tool groups to enable. See feature groups.

When using the URL in the dashboard or docs, these parameters will be populated for you.

Project scoped mode

Without project scoping, the MCP server will have access to all projects in your Supabase organization. We recommend you restrict the server to a specific project by setting the project_ref query parameter in the server URL:

https://mcp.supabase.com/mcp?project_ref=<project-ref>

Replace <project-ref> with the ID of your project. You can find this under Project ID in your Supabase project settings.

After scoping the server to a project, account-level tools like list_projects and list_organizations will no longer be available. The server will only have acce
