# Supabase (MCP OAuth) - How do I link my account?

> Connect Supabase MCP with Nango using OAuth and your project reference

# Overview

To connect **Supabase (MCP OAuth)** with Nango you need:

1. **Project reference** — The 20-character ID of your Supabase project.

Nango handles OAuth client registration automatically — you don't need to create an app in Supabase or obtain a client ID and secret manually.

### Prerequisites

* A Supabase account and at least one project

### Instructions:

#### Step 1: Finding your project reference

Your project reference is the 20-character ID that identifies your Supabase project:

1. Open the [Supabase Dashboard](https://supabase.com/dashboard) and select your project.
2. Obtain the ID from the project URL: `https://supabase.com/dashboard/project/<project-ref>/...` in your browser address bar.

#### Step 2: Enter credentials in the Connect UI

Once you have your **Project reference**:

1. Open the form where you need to authenticate with Supabase (MCP OAuth).
2. Enter your **Project reference** in its respective field.
3. Submit the form, and you should be successfully authenticated.
