```

## 🚀 Quick Start

### 1. Installation

```bash
git clone https://github.com/nicotordev/v0-mcp-ts.git
cd v0-mcp-ts
bun install  # ⚡ 25x faster than npm install
```

### 2. Setup

```bash
bun run setup
```

This interactive setup will:

- Configure your v0.dev API key
- Build the project with Bun
- Run tests with coverage
- Generate MCP client configuration

### 3. Configuration

#### For Claude Desktop

Copy the generated configuration to your Claude Desktop config:

```json
{
  "mcpServers": {
    "v0-mcp-ts": {
      "command": "node",
      "args": ["/absolute/path/to/v0-mcp-ts/dist/index.js"],
      "env": {
        "V0_API_KEY": "your_v0_api_key_here"
      }
    }
  }
}
```

#### For Other MCP Clients

The server uses standard stdio transport, making it compatible with any MCP client.
