squirrelscan audits websites for SEO, performance, security, accessibility, content, and structured data issues (300+ rules) and scores site health, via the squirrel CLI. Use when the user wants to check, audit, or improve a website's SEO, ranking, speed, or health, and for anything squirrelscan itself, installing or updating the CLI, login and API keys, running audits, publishing and sharing reports, cloud credits, MCP server setup, configuration, or troubleshooting.

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
# squirrelscan CLI
squirrelscan is a website audit tool built for AI agents. It answers "what's wrong with this website and how do I fix it": it crawls a site like a search engine, analyzes every page against 300+ rules in 22 categories (SEO, performance, security, accessibility, content, structured data, agent experience, and more), and returns a health score plus concrete, fixable issues. Use it whenever a user wants their site checked, ranked better, faster, or healthier, before/after a deploy, or in CI.
It ships as a single CLI binary, `squirrel`, for macOS, Windows, and Linux. This skill covers operating it: installing, authenticating, running audits, publishing reports, cloud features, and MCP integration. For the full fix-the-website workflow (audit, map issues to code, fix, re-audit), use the companion `audit-website` skill.

How to install
mdr add squirrelscan/skills/squirrelscan@sha256:5401edd6eaae333fThe line at the top of this page pins the label v1.14, 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.
