Overview

What Argus Does

Argus audits your running web app for bugs that test suites miss — no test scripts required. Point it at a URL and it runs 24 analysis engines via Chrome DevTools Protocol.

Four MCP Tools

Tool	What it does
`argus_audit`	Fast QA audit — JS errors, network failures, SEO, security, accessibility
`argus_audit_full`	Deep audit — adds Lighthouse, responsive layout, memory leaks, hover bugs
`argus_compare`	Diff dev vs staging side-by-side
`argus_last_report`	Fetch the last saved report JSON

What It Catches

JavaScript runtime errors and unhandled promise rejections
HTTP 4xx/5xx failures and API frequency loops
Accessibility violations (Lighthouse + ARIA snapshot)
Missing SEO tags, broken images, placeholder content
Security issues — localStorage tokens, missing CSP, eval() usage
Visual regressions between environments
Memory leaks via V8 heap snapshot

Requirements

Node.js ≥ 20.19
Chrome running with --remote-debugging-port=9222
chrome-devtools-mcp registered alongside Argus
