What is the Squirrelscan MCP server?

If you already use Squirrelscan, the squirrelscan mcp server is the piece that lets your assistant work with it directly. Audit websites for SEO, performance, security, accessibility and agent experience issues.

What the server does

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.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • LLM — native output for AI-assisted debugging and optimization
  • Skill — What it does
  • Cursor — npx skills add squirrelscan/skills, or the plugin / MCP deeplink below
  • Manual — clone + symlink skills/* into your agent's skills dir

Credentials and setup notes

All skills drive the squirrel CLI, which must be installed and in PATH. Install: squirrelscan.com/download Verify:

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Squirrelscan's toolset — LLM, Skill, Cursor and 1 more — is a fair guide to whether it matches your workflow. It is maintained by com.squirrelscan; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
