# Claude in Chrome

Ask Claude about a part while you look at it in the modeler or on its catalog page.

[Claude in Chrome](https://support.claude.com/en/articles/12012173-get-started-with-claude-in-chrome) is a browser extension. Its agent works on the page you have open: it reads the page, takes screenshots, and clicks and types as you would.

Open its side panel on the modeler, or on a device's catalog page, and ask, e.g. "the height doesn't make sense, fix it". It can help in two ways.

## On the page

The **Agent brief** card lists everything an agent needs, in millimetres:

- a summary of the device;
- every measurement, with its source;
- each face's size;
- the ports and their positions;
- your open annotations;
- how to connect the MCP server.

The face editor states how many millimetres one pixel is, so positions read off a screenshot come out right. Every form field has a clear name, so the agent can change values the way you would.

**Copy context for your agent** copies the brief as Markdown, to paste into any chat.

## Over MCP

If you've added Rack Maker as a connector in Claude, it works in Claude in Chrome too. Your agent's edits then apply directly to your draft and show up live. It works through your [annotations](https://rack-maker.cbnsndwch.dev/docs/modeler/annotations) and [measurement form](https://rack-maker.cbnsndwch.dev/docs/modeler/measurement-forms), resolving each one with a note. See [Using AI agents](https://rack-maker.cbnsndwch.dev/docs/agents) for how to connect.
