### Description (declared)

# claude-collab-mcp

MCP server for async collaboration between two Claude users via shared project state.

Two people using Claude (Claude Code, Claude Desktop, or any MCP-compatible client) can share live project context through a Supabase backend. No cloud hosting required.

## Installation

```bash
# Using uvx (recommended, no install needed)
uvx claude-collab-mcp

# Or install with pip
pip install claude-collab-mcp

# Or install with uv
uv pip install claude-collab-mcp
```

## Setup

### 1. Create a Supabase Project

1. Go to [supabase.com](https://supabase.com) and create a free project
2. Run the schema setup in your Supabase SQL editor (see [setup.sql](setup.sql))
3. Copy your project URL and anon key from Settings > API

### 2. Configure Environment Variables

Each user needs three environment variables:

```bash
SUPABASE_URL=https://your-project.supabase.co
SUPABASE_KEY=your-anon-key
COLLAB_USER=kelly  # or justin, or any identifier
```

### 3. Add to Your Claude Client

**Claude Code:**
```bash
claude mcp add claude-collab -s user -e SUPABASE_URL=https://... -e SUPABASE_KEY=... -e COLLAB_USER=kelly -- uvx claude-collab-mcp
```

**Claude Desktop** (`~/Library/Application Support/Claude/claude_desktop_config.json`):
```json
{
  "mcpServers": {
    "claude-collab": {
      "command": "uvx",
      "args": ["claude-collab-mcp"],
      "env": {
        "SUPABASE_URL": "https://your-project.supabase.co",
        "SUPABASE_KEY": "your-anon-key",
        "COLLAB_USER": "justin"
      }
    }
  }
}
```

## Tools
