# Lighthouse MCP Server

An MCP server that wraps around Google's Lighthouse tool to help measure various performance metrics for web pages.

## Features

- Run comprehensive Lighthouse audits on any URL
- Get performance scores and metrics
- Configure device emulation (mobile/desktop)
- Control network throttling
- Select specific audit categories

## Installation

### Option 1: From MCP Registry (Recommended)

This server is available in the [Model Context Protocol Registry](https://registry.modelcontextprotocol.io/servers/io.github.priyankark/lighthouse-mcp). Install it using your MCP client or Claude Desktop.

### Option 2: Using npx

You can run the tool directly using npx without installation:

```bash
npx lighthouse-mcp
```

### Option 3: Global Installation

```bash
npm install -g lighthouse-mcp
```

Then run it:

```bash
lighthouse-mcp
```

### Option 4: Local Development

1. Clone this repository
2. Install dependencies:
   ```bash
   npm install
   ```
3. Build the project:
   ```bash
   npm run build
   ```
4. Run the server:
   ```bash
   npm start
   ```

## MCP Configuration

### When installed via npm (global or npx)

Add the following to your MCP settings configuration file:

```json
{
  "mcpServers": {
    "lighthouse": {
      "command": "npx",
      "args": ["lighthouse-mcp"],
      "disabled": false,
      "autoApprove": []
    }
  }
}
```

### When using local development version

Add the following to your MCP settings configuration file:

```json
{
  "mcpServers": {
    "lighthouse": {
      "command": "node",
      "args": ["/absolute/path/to/lighthouse-mcp/build/index.js"],
      "disabled": false,
      "autoApprove": []
    }
  }
}
```

Replace `/absolute/path/to/lighthouse-mcp` with the actual path to this project.
