Chrome DevTools MCP Setup

Overview

Chrome DevTools MCP requires Chrome running with remote debugging enabled. Without this, all mcp__chrome-devtools__* tool calls fail.

When to Use

Before first use of any mcp__chrome-devtools__* tool
When error: "Could not connect to Chrome" or "Could not find DevToolsActivePort"

Setup

Run the launch script via Bash tool:

~/.claude/skills/chrome-devtools/scripts/launch-chrome-debug.sh

The script handles everything automatically: quits existing Chrome, launches with debug flags, waits and verifies the connection. If Chrome debug mode is already running, it skips and reuses it.

MCP Installation

If mcp__chrome-devtools__* tools are not available, guide the user to install the MCP server:

claude mcp add --scope user chrome-devtools -- npx chrome-devtools-mcp@latest --autoConnect

The user needs to restart Claude Code after installation for the MCP tools to become available.

Common Errors

Error	Fix
"Could not connect to Chrome"	Run setup command
"Could not find DevToolsActivePort"	Quit Chrome first, then run setup command
Port 9222 already in use	Another debug Chrome is running; use it or kill it first
