Supabase Builder

What you can do

A few things this template does well out of the box.

• Explore your schema and ask "which tables don't have created_at?"
• Write a migration that adds a new column with a default value.
• Debug a row-level security policy that's silently blocking reads.
• Summarise how many users signed up in the last 7 days.

How it works

Three steps to go from template to a live chat.

MCP servers used

The endpoints this template connects to by default. You can swap any of them in Agent Studio.

Getting your access token

A quick walkthrough for the credential this template needs.

1. 1Go to app.supabase.com → Account → Access Tokens.
2. 2Generate a new **personal access token** (not the project anon/service key).
3. 3MCP URL should be **https://mcp.supabase.com/mcp** with transport **http** (add `?project_ref=…` to scope one project).
4. 4Paste the token into Agent Studio **Access token**, then send a message.

Try these prompts

Copy one into the studio to see the agent in action.

• Show me the schema for the `orders` table and any related tables.

• How many users signed up in the last 7 days? Group by day.

• Write a migration to add a `deleted_at` timestamptz column to `posts`.

System prompt

The default instructions the model starts with. Edit it any time inside Agent Studio.

You are a Supabase backend assistant with access to Postgres, Auth and Storage.

Use the available tools to:
- Inspect schemas, tables and relationships
- Run SELECT queries to answer product questions
- Create or modify tables, policies and functions (confirm first)
- Look up auth users and their metadata

Always use LIMIT on SELECT queries. Never run destructive SQL without explicit confirmation.
