# Chrome DevTools MCP

> A developer-focused comparison of GreaseClaw MCP and Chrome DevTools MCP for browser automation

Both GreaseClaw MCP and [Chrome DevTools MCP](https://github.com/ChromeDevTools/chrome-devtools-mcp) give AI agents control over a browser via the Model Context Protocol. But they're built for different scopes. Chrome DevTools MCP focuses on debugging and inspection, while GreaseClaw MCP is a complete browser automation and app integration platform.

This page breaks down the differences for developers evaluating which to use with Claude Code, Gemini CLI, Cursor, or any MCP client.

## Setup Comparison

<Tabs>
  <Tab title="GreaseClaw MCP">
    GreaseClaw MCP is built into the browser. No separate process, no debug flags.

    ```bash theme={null}
    # One command, done
    claude mcp add --transport http browseros http://127.0.0.1:9239/mcp --scope user
    ```

    The server URL is available at `chrome://browseros/mcp`. Copy it and connect.
  </Tab>

  <Tab title="Chrome DevTools MCP">
    Chrome DevTools MCP requires launching Chrome with remote debugging enabled and running a separate Node.js server.

    ```bash theme={null}
    # Step 1: Launch Chrome with debug port
    /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222

    # Step 2: Install and run the MCP server
    npx @anthropic-ai/chrome-devtools-mcp@latest

    # Step 3: Connect your MCP client to the server
    ```

    Some sites may block sign-in when the browser is controlled via WebDriver (the default launch mechanism).

GreaseClaw MCP gives you a broader automation surface: browser control, content extraction, file operations, and 40+ app integrations through a single connection. Debugging and performance tools are coming soon to GreaseClaw MCP, which will close the remaining gap with Chrome DevTools MCP. For most AI agent workflows, GreaseClaw MCP already covers more ground out of the box.
