Chrome DevTools MCP

Both GreaseClaw MCP and 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

GreaseClaw MCP
Chrome DevTools MCP

GreaseClaw MCP is built into the browser. No separate process, no debug flags.

# 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.

Chrome DevTools MCP requires launching Chrome with remote debugging enabled and running a separate Node.js server.

# 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).
