Chrome DevTools (existing tab)

Attach to the Chrome the user already has open through Pi's chrome-devtools MCP server. Do not start a second Chrome.

Do not call PATH chrome-devtools, chrome-devtools-mcp, or a CLI daemon. bunx / npx chrome-devtools-mcp is the MCP server bin; Pi starts it. The sibling chrome-devtools bin is the old daemon CLI and is not this path.

Once connected, call only:

• mcp__chrome_devtools__list_pages
• mcp__chrome_devtools__evaluate_script
• mcp__chrome_devtools__take_screenshot

The server name chrome-devtools becomes chrome_devtools in the tool name.

Server

User-level only: ~/.pi/agent/mcp.json. Do not write this into a project .pi/mcp.json.
