Agent Audit MCP server

Agent Audit

Lighthouse-powered MCP server for AI coding agents, Core Web Vitals, technical SEO, accessibility, and GEO/LLM visibility audits.

🔗 NPM Package

Agent Audit turns Google Lighthouse and bounded page-inspection results into structured fix packs that coding agents can actually execute. It gives Claude Code, Codex, Cursor, GitHub Copilot, and other MCP clients a prioritized, evidence-backed backlog instead of a raw performance report.

Turn Lighthouse audits into coding-agent fix packs.

Why Agent Audit Exists

Lighthouse is excellent for diagnosis, but raw reports are not enough for an autonomous coding workflow. A coding agent still needs to know which issue is most important, whether it affects mobile, desktop, or both, which selectors or resources are evidence, what files to search for, how to verify the fix, and when it is safe to claim completion.

Agent Audit converts Lighthouse output into an implementation contract:

structured data, images, assets, indexability, and AI discovery signals.

1. Runs mobile and desktop Lighthouse audits.
2. Aggregates repeated runs and exposes variability.
3. Adds bounded same-page intelligence for technical SEO, links, metadata,

measurable acceptance criteria.

1. Merges noisy audit output into a small prioritized issue list.
2. Generates fixPacks with repo search hints, implementation steps, and

1. Returns strict MCP structuredContent plus equivalent Markdown.

The goal is simple: give a coding agent a report it can read, reason about, fix, test, and verify.
