What is squirrelscan?
A report worth sharing
Every audit produces a health score, a category breakdown, and fix-it guidance for each issue — rendered as a self-contained HTML report, or six other formats for humans and agents alike.

Four ways to run it
Same audit engine, same report — four front doors: your terminal, your coding agent, the cloud, or MCP.
CLI
A single binary, zero dependencies. Audit from your terminal and pipe results anywhere.
In your agent
An install-on-demand skill for Claude Code, Cursor, and any coding agent.
Cloud
Browser rendering, AI analysis, and shareable reports — billed in credits.
MCP
A local stdio server (squirrel mcp) that exposes the audit engine and cloud features as agent tools.
Wiring it into CI? squirrelscan returns CI-friendly exit codes — fail the build on score or severity thresholds.
