### Description (declared)

# clr-supabase-mcp

MCP server for self-hosted Supabase instances with multi-instance support.

## Features

- Schema introspection, SQL execution, migrations
- Auth user management (GoTrue)
- Storage bucket/object management
- Edge function management
- Multi-instance support via credentials.json
- Module-based tool loading (`--modules` flag)
- Read-only mode

## Installation

```bash
pip install clr-supabase-mcp
```

## Configuration

### Step 1: Create the credentials directory

```bash
mkdir -p ~/.config/supabase
```

### Step 2: Find your Supabase credentials

You need three values from your self-hosted Supabase deployment:

**1. Supabase URL** — The public Kong gateway URL for your instance. This is the URL you use to access the Supabase API (e.g. `https://supabase.example.com`). If you're running Supabase locally via Docker, this is typically `http://localhost:8000`.

**2. Service Role Key** — The `service_role` JWT key that grants admin access. Find it in your Supabase `.env` file:
```bash
# In your Supabase deployment directory:
grep SERVICE_ROLE_KEY .env
# or look for the value of SUPABASE_SERVICE_ROLE_KEY
```
This key looks like `eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...` (a long JWT token).

**3. Database URL** — Direct PostgreSQL connection string. Build it from values in your Supabase `.env` file:
```
postgresql://postgres:YOUR_POSTGRES_PASSWORD@YOUR_DB_HOST:5432/postgres
```

Find the password:
```bash
grep POSTGRES_PASSWORD .env
```

The DB host depends on your setup:
- **Docker on same machine:** `localhost` (or the mapped port, check `docker compose ps`)
- **Remote server:** The hostname/IP of your database server
- **Docker network name:** `db` (if connecting from within the same Docker network)

### Step 3: Create credentials.json

**Single instance:**

```bash
cat > ~/.config/supabase/credentials.json << 'EOF'
{
  "url": "https://supabase.example.com",
  "service_key": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "db_url": "postgresql://postgres:…
