Website audits for AI agents: skills, plugins, and MCP in one repo
What is squirrelscan?
squirrelscan is a website audit tool built for AI agents. It crawls a site, analyzes every page against 260+ rules across SEO, performance, security, accessibility, content, and more, and returns a health score plus concrete, fixable issues.
Features:
- 260+ audit rules across 21 categories
- Leaked secrets detection (96 patterns: OpenAI, Anthropic, AWS, Stripe, and more)
- Multiple output formats: console, text, json, markdown, llm, html
- Diff reports for regressions between audits
- LLM-native output for AI-assisted debugging and optimization
- Optimized for CI/CD pipelines and automation
What's in this repo
| Skill | What it does |
|---|---|
squirrelscan | Operate the CLI: install, login, run audits, publish reports, credits, API keys, MCP setup, config, troubleshooting |
audit-website | The fix loop: audit a site, map findings to code, fix in batches, re-audit until it scores well |
The repo is also a Claude Code plugin + marketplace and a Cursor plugin, bundling both skills and the hosted squirrelscan MCP server.
Prerequisites
All skills drive the squirrel CLI, which must be installed and in PATH.

Installing
Pick the path for your tool:
| Tool | Install |
|---|---|
| Any agent (Agent Skills standard) | npx skills add squirrelscan/skills |
| Claude Code | /plugin marketplace add squirrelscan/skills then /plugin install squirrelscan@squirrelscan |
| Cursor | npx skills add squirrelscan/skills, or the plugin / MCP deeplink below |
| OpenAI Codex | npx skills add squirrelscan/skills (lands in .agents/skills/) |
| squirrel CLI | squirrel skills install |
| Manual | clone + symlink skills/* into your agent's skills dir |
Agent Skills via npx (works everywhere)
Installs both skills (squirrelscan and audit-website) for whichever agents you select: Claude Code, Codex, Cursor, Gemini CLI, Amp, and more. Skills follow the Agent Skills standard, so the same SKILL.md works across tools. To install just one skill:
Claude Code plugin (recommended for Claude Code)
One step installs both skills and connects the hosted squirrelscan MCP server. Updates ship automatically with new commits to this repo.
Cursor
Three options, lightest to fullest:
- Skills:
npx skills add squirrelscan/skills. Cursor reads Agent Skills from.cursor/skills/,.agents/skills/, and their~/equivalents (it also picks up~/.claude/skills/). - MCP only, one click: Add squirrelscan MCP to Cursor
- Plugin: this repo is also a Cursor plugin (
.cursor-plugin/) bundling both skills and the MCP server, for install via the Cursor Marketplace.
OpenAI Codex
Codex reads skills from .agents/skills/ (project) or ~/.agents/skills/ (global). npx skills add squirrelscan/skills installs there, or clone and symlink the skills/* directories.
From the squirrel CLI
Manual
Then copy or symlink skills/squirrelscan and skills/audit-website into your agent's skills directory (make link does this for Claude Code and .agents/skills consumers).
MCP server
The hosted MCP server lives at https://mcp.squirrelscan.com/mcp (streamable-http; OAuth or Authorization: Bearer sq_... API key). A local stdio server is available via squirrel mcp. Docs: docs.squirrelscan.com/developers/mcp
