How to install cbrowser

cbrowser is published on npm as cbrowser, and it depends on @modelcontextprotocol/sdk. These steps assume it runs as a local stdio server, which is the usual setup.

Check the README. Confirm the start command and note any API keys or environment variables it needs (pass them with -e KEY=value or an env block). You need Node.js for npx.

Add it to Claude Code from a terminal:

claude mcp add cbrowser -- npx -y cbrowser

Or add it to Cursor or Claude Desktop in .cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "cbrowser": {
      "command": "npx",
      "args": [
        "-y",
        "cbrowser"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm cbrowser and its tools are listed. The install guide covers VS Code and Codex.
