Install squirrelscan

v0.0.133·Released Oct 24, 2026·View changelog

squirrelscan is a command line website audit tool for developers and AI agents, with 309 audit rules across SEO, performance, security and more. Install the CLI below, or skip the install entirely and run a cloud audit from the dashboard.

Quick install

Run this command to automatically install the latest version

Or with Homebrew:

The cask runs the regular installer the first time you run squirrel, then squirrel updates itself.

Then run squirrel setup to sign in (optional), install the agent skills and keep squirrel up to date.


Add it to your coding agent

Two skills: squirrelscan runs the CLI for your agent, and audit-website audits a site, fixes what it finds and re-audits.

squirrel CLI

Installs both skills for Claude Code, Codex, Cursor and other Agent Skills tools. squirrel setup runs it for you, and auto-update keeps them current.

Claude Code plugin

Both skills plus the hosted MCP server, in one plugin.

MCP server

Cloud audits, reports and issues as tools in your agent. Other MCP clients

npx skills

Just the skills, for any Agent Skills tool, without the squirrel CLI.

Then ask your agent to “audit my site with squirrelscan and fix what you find”. Opt in to the Claude Code channel to push cloud audit results into a running session.
