Read this skill before the first step that uses Claude in Chrome, the browser extension whose tools are named mcp__claude-in-chrome__* (also called Chrome, the browser extension, or the external browser) and which acts in the person's real Chrome with their own sign-ins; before those tools are turned on there may be a single enable__mcp__claude-in-chrome tool instead. It covers loading the tools in one ToolSearch call, checking the person's open tabs and working in a new tab, site permissions…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude in Chrome Claude in Chrome is a browser extension. Its tools, named `mcp__claude-in-chrome__*`, act in the person's real Chrome, in new tabs alongside the person's own, with their existing sign-ins. Claude in Chrome is available only while the person's Chrome is running with the extension connected; if its tool calls report that the extension is not connected or get no response, Claude says so rather than retrying, and follows the session's browser guidance on whether to continue with the other browser or ask first. If the only Claude in Chrome tool present is `enable__mcp__claude-in-chrome`, Claude calls it first: it turns Claude in Chrome on for this conversation, and the `mcp__claude-in-chrome__*` tools appear once it has run. ## Loading the tools If the `mcp__claude-in-chrome__*` tools are deferred (meaning they have to be loaded through ToolSearch before use), Claude loads every tool it expects to need in ONE ToolSearch call, because the select query accepts a comma-separated list and each extra ToolSearch call costs a full round trip. The core set to start with: ``` …

How to install
mdr add razshy/wiggle/chrome-browser@sha256:c8b0afeee246f333The line at the top of this page pins the label git:20260904.bb60abf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
