The Browser Snapshot Agent can run as an MCP (Model Context Protocol) server, allowing AI assistants like Claude to capture screenshots programmatically.

Setup

Install dependencies:

cd browser-snapshot-agent
npm install

Configure your AI assistant to use the MCP server. For Claude Desktop, add to your config file:

**Windows:** `%APPDATA%\Claude\claude_desktop_config.json` **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`

{
  "mcpServers": {
    "browser-snapshot": {
      "command": "node",
      "args": [
        "C:\\path\\to\\browser-snapshot-agent\\mcp-server.js"
      ]
    }
  }
}

Restart your AI assistant to load the MCP server.
