Supabase (MCP OAuth)

🚀 Quickstart

Connect to the Supabase MCP server with Nango via OAuth. Nango automatically registers an OAuth client on your behalf — no manual credential setup required.

Create the integration

In Nango (free signup), go to Integrations → Configure New Integration → Supabase (MCP OAuth).Nango will automatically register an OAuth client with Supabase using dynamic client registration. Your Client ID and Client Secret will appear in the integration settings once created.

Authorize Supabase

Go to Connections → Add Test Connection → Authorize, then log in to your Supabase account and grant access. Later, you’ll let your users do the same directly from your app.

Call the Supabase MCP server

Make your first MCP request (e.g. list tools). Replace the placeholders below with your secret key, integration ID, and connection ID.For <PROJECT-REF>, use the project reference you entered when creating the connection. You can find it on the connection details page under Connection Config → projectRef.

cURL
Node

curl "https://api.nango.dev/proxy/mcp?project_ref=<PROJECT-REF>" \
  -X POST \
  -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list",
    "params": {}
}'

Install Nango’s backend SDK with npm i @nangohq/node. Then run:

import { Nango } from '@nangohq/node';

const nango = new Nango({ secretKey: '<NANGO-SECRET-KEY>' });

const res = await nango.post({
    endpoint: '/mcp?project_ref=<PROJECT-REF>',
    providerConfigKey: '<INTEGRATION-ID>',
    connectionId: '<CONNECTION-ID>',
    body: {
        jsonrpc: '2.0',
        id: 1,
        method: 'tools/list',
        params: {}
    }
});

console.log(res.data);
