The website QA tool for your coding agent
squirrelscan is an Open Source cli tool that audits websites for SEO, performance, security, accessibility, agent experience and other issues, and gives your coding agent exact fixes. Run it from the CLI, inside your coding agent, in the cloud, or over MCP.
Website QA for your coding agent: audit SEO, performance, security, accessibility over MCP.
Combine your coding agent with a deterministic and extensible audit tool.
A real run on a tiny test site, with the released CLI (signed out, so free) and Claude Code. We cut the two minutes the agent spent working, because nobody wants to watch an agent think.
Ordered by how much a failure usually costs you, not by how many rules each one has.
Total: 300+ rules across 22 categories
See the rules reference for full details.
Paste into your coding agent (Claude Code, Codex, Cursor, opencode and friends):
Fetch and follow the setup instructions for squirrelscan at https://docs.squirrelscan.com/agent-setup/prompt.md
Your agent installs the CLI, connects MCP and runs a first audit. You can read exactly what it will follow first.
macOS / Linux:
curl -fsSL https://install.squirrelscan.com | bash
Windows:
iwr -useb https://install.squirrelscan.com/install.ps1 | iex
Homebrew (macOS):
brew install --cask squirrelscan/tap/squirrel
The cask installs a launcher that runs the regular installer on first use. The CLI then updates itself with squirrel self update; brew upgrade leaves it alone.
npm (all platforms):
npm install -g squirrelscan
npx (run without installing):
npx squirrelscan audit example.com
# Audit a website
squirrel audit example.com
# Generate HTML report
squirrel audit example.com -f html -o report.html
# Pipe to Claude for AI analysis
squirrel audit example.com --format llm | claude
# Quick audit for a fast first look (other levels: surface, full)
squirrel audit example.com --level quick
# run only agent experience and performance rules
squirrel audit example.com --rule-include ax,performance
# login for cloud audits and cloud rendering
squirrel auth login

squirrelscan ships as an MCP server (hosted at mcp.squirrelscan.com), skills (autonomous audit + fix workflows), and a plugin for Claude Code and Cursor. Cursor installs in one click from the badge above; the rest are a single copy-paste.
Click the Add to Cursor badge above, or add it manually to ~/.cursor/mcp.json:
{
"mcpServers": {
"squirrelscan": { "url": "https://mcp.squirrelscan.com/mcp" }
}
}
Skills: squirrel skills install
Install the plugin (bundles skills + the MCP server):
/plugin marketplace add squirrelscan/skills
/plugin install squirrelscan@squirrelscan
Or add just the MCP server:
claude mcp add --transport http squirrelscan https://mcp.squirrelscan.com/mcp
Add the server to ~/.codex/config.toml:
[mcp_servers.squirrelscan]
url = "https://mcp.squirrelscan.com/mcp"
Codex reads Agent Skills from ~/.agents/skills, so skills work too: squirrel skills install
Add the server to opencode.json:
{
"$schema": "https://opencode.ai/config.json",
"mcp": {
"squirrelscan": {
"type": "remote",
"url": "https://mcp.squirrelscan.com/mcp",
"enabled": true
}
}
}
squirrelscan is in the MCP Registry as com.squirrelscan/squirrelscan. Point any client at the remote server:
https://mcp.squirrelscan.com/mcp
Authentication is per-user OAuth (or pass a squirrelscan API key as a Bearer token). Skills follow the Agent Skills standard: squirrel skills install puts them in ~/.agents/skills/ and ~/.claude/skills/.
Two skills drive agent workflows. They live in squirrelscan/skills, along with the Claude Code, Cursor and Agent Plugins packages that bundle them with the MCP server. squirrel skills install downloads and verifies them itself, and from v0.0.99 squirrel's auto-update keeps them current. Installs made earlier with npx skills are taken over.
squirrelscan - operating the CLI: install, login, keys, credits, running audits, publishing reports, the entity map, MCP setup, config, troubleshooting.audit-website - the full fix loop: audit, map issues to source files, fix in batches, re-audit until the site scores well.squirrel skills install
Then, in your agent:
Use the audit-website skill to audit this site and fix all issues but only crawl 10 pages
The complete local CLI, crawler, audit engine, rules, report generators, CLI-facing cloud clients, and documentation site are open source in this repository. The hosted API, website, dashboard, and cloud worker implementations are separate private services.
Prerequisites: Bun 1.4.0 and Git.
git clone https://github.com/squirrelscan/squirrelscan.git
cd squirrelscan
bun install --frozen-lockfile
bun run dev -- audit https://example.com --max-pages 10
Run the same checks used in pull requests:
bun run format:check
bun run lint
bun run typecheck
bun test
bun run build
bun run docs:check

See CONTRIBUTING.md before opening a pull request. Contributions require a Developer Certificate of Origin sign-off (git commit -s).
Telemetry is enabled by default and is deliberately minimal: event name, CLI version, a random install ID, and bounded error categories. It does not send credentials, URLs, report contents, or raw error messages, and telemetry requests are never authenticated.
Disable it permanently with:
squirrel self settings set telemetry false
Or disable all telemetry and install registration for any invocation by defining NO_TELEMETRY. Any defined value works, including an empty value, 0, or false:
NO_TELEMETRY=1 squirrel audit https://example.com
If squirrelscan caught something your agent missed, a star on GitHub helps other developers find it.
