PackDev tools

chrome-devtools-mcp is a plugin that gives an AI agent control of Chrome through Chrome DevTools and Puppeteer. It handles chrome ai integration so the agent can automate browser tasks, debug webpages, and analyse page performance. This is useful when a coding or browsing agent needs to see and interact with real pages instead of guessing at their behaviour.

Unavailable. Delivery for this kind is on the roadmap — not serving yet.

Have Chrome available on the machine where the agent runs.

What your AI can do with it

Automate Chrome browser tasks from an agent

Drive Chrome through Puppeteer automation

Getting started

Have Chrome available on the machine where the agent runs.
Add the chrome-devtools-mcp plugin to the agent's configuration.
Confirm the agent can start a browser session and open a page.
Ask the agent to automate, debug, or profile a page to verify the setup.
