Claude in Chrome MCP Troubleshooting

Use this skill when Claude in Chrome MCP tools fail to connect or work unreliably.

When to Use

• mcp__claude-in-chrome__* tools fail with "Browser extension is not connected"
• Browser automation works erratically or times out
• After updating Claude Code or Claude.app
• When switching between Claude Code CLI and Claude.app (Cowork)
• Native host process is running but MCP tools still fail

When NOT to Use

• Linux or Windows users - This skill covers macOS-specific paths and tools (~/Library/Application Support/, osascript)
• General Chrome automation issues unrelated to the Claude extension
• Claude.app desktop issues (not browser-related)
• Network connectivity problems
• Chrome extension installation issues (use Chrome Web Store support)
