The Supabase MCP Server connects your Supabase projects to AI assistants like Cursor, Claude, and Windsurf using the Model Context Protocol (MCP). This standardized protocol allows AI assistants to interact directly with your Supabase project to manage tables, fetch configuration, and query data.
You need Node.js installed on your machine. Verify your installation by running:
node -v
If Node.js isn't installed, download it from nodejs.org.
Configure your MCP client (such as Cursor) with the following JSON configuration:
{
"mcpServers": {
"supabase": {
"command": "npx",
"args": [
"-y",
"@supabase/mcp-server-supabase@latest",
"--read-only",
"--project-ref=<project-ref>"
],
"env": {
"SUPABASE_ACCESS_TOKEN": "<personal-access-token>"
}
}
}
}
Replace <personal-access-token>
with your token from Step 1 and <project-ref>
with your Supabase project ID.
On Windows, prefix the command with cmd /c
:
{
"mcpServers": {
"supabase": {
"command": "cmd",
"args": [
"/c",
"npx",
"-y",
"@supabase/mcp-server-supabase@latest",
"--read-only",
"--project-ref=<project-ref>"
],
"env": {
"SUPABASE_ACCESS_TOKEN": "<personal-access-token>"
}
}
}
}
If using WSL, use this configuration instead:
{
"mcpServers": {
"supabase": {
"command": "wsl",
"args": [
"npx",
"-y",
"@supabase/mcp-server-supabase@latest",
"--read-only",
"--project-ref=<project-ref>"
],
"env": {
"SUPABASE_ACCESS_TOKEN": "<personal-access-token>"
}
}
}
}
Make sure Node.js is in your PATH environment variable:
Find npm's location:
npm config get prefix
Add it to your PATH:
setx PATH "%PATH%;<path-to-dir>"
Restart your MCP client
Restrict the server to a specific project using the --project-ref
flag:
npx -y @supabase/mcp-server-supabase@latest --project-ref=<project-ref>
Find your project ID in your Supabase project settings under "Project ID".
Enable read-only mode to prevent write operations:
npx -y @supabase/mcp-server-supabase@latest --read-only
This is recommended for security as it restricts database operations to read-only.
Enable specific tool groups with the --features
flag:
npx -y @supabase/mcp-server-supabase@latest --features=database,docs
Available groups:

: Supabase documentation searchdatabase

claude mcp add-json "supabase" '{"command":"npx","args":["-y","@supabase/mcp-server-supabase@latest","--read-only","--project-ref=<project-ref>"],"env":{"SUPABASE_ACCESS_TOKEN":"<personal-access-token>"}}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"supabase": {
"command": "npx",
"args": [
"-y",
"@supabase/mcp-server-supabase@latest",
"--read-only",
"--project-ref=<project-ref>"
],
"env": {
"SUPABASE_ACCESS_TOKEN": "<personal-access-token>"
}
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json
%APPDATA%\Claude\claude_desktop_config.json
~/.config/Claude/claude_desktop_config.json
2. Add this to your configuration file:
{
"mcpServers": {
"supabase": {
"command": "npx",
"args": [
"-y",
"@supabase/mcp-server-supabase@latest",
"--read-only",
"--project-ref=<project-ref>"
],
"env": {
"SUPABASE_ACCESS_TOKEN": "<personal-access-token>"
}
}
}
}
3. Restart Claude Desktop for the changes to take effect
