OUR ASSESSMENT
- 57 GitHub stars.
- 6 commits on main in the last 30 days.
- MIT license.
- No authentication required.
- Covers all four Lighthouse audit categories (performance, accessibility, SEO, best-practices).
- Audit comparison supports before/after measurement.
- Lighthouse audits take 20-60 seconds; agent invocation timeout may need raising.
- Headless Chromium download on first run (~100MB).
- Community-maintained.
No authentication. Lighthouse runs a headless browser against arbitrary URLs; honour target site Terms of Service before running large audit batches. Audit reports may include screenshots; treat scan output as having access to whatever was rendered.
Performance-budget agents that audit pages on every PR; SEO flows where the agent runs Lighthouse and proposes fixes; accessibility audits inside the agent loop.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 4 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 4 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
