Security profile

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works

9 of 9 tools

Documented tools (9)

From project documentation. A server handshake does not verify each tool’s description or behavior.

argus_audit

Fast pass — JS, network, accessibility, SEO, security, CSS, content

argus_audit_full

Deep pass — adds Lighthouse, responsive checks, memory leak detection, hover-state bugs

argus_compare

Diff dev vs staging — screenshots, findings delta, environment regressions

argus_design_audit

Figma URL → 13 design-token finding types (color, spacing, typography, shadows, etc.)

argus_get_context

Capture everything broken on the open tab — with resolved / new / persisting diff vs the last snapshot (the fix loop)

argus_last_report

Return last JSON report without re-running

argus_pr_validate

Fetch GitHub PR diff → map changed files to affected routes → targeted audit → baseline-aware block decision (blocks on findings the PR introduces) + idempotent PR comment + Check Run → { blocked, findings, baseline, reporting }

argus_visual_diff

Screenshot baseline comparison. Pass updateBaseline: true to reset.

argus_watch_snapshot

Snapshot the open tab without navigating (preserves auth/form state)
