Open Source MCP Server Enables One-Click Full-Site SEO Audits
MK_0181 · reddit · 2026-08-10
Developer mk-techi has open-sourced an MCP Server (mcp-seo-audit) designed specifically for on-page SEO audits, empowering AI assistants to take over tedious manual auditing tasks.
The tool features 7 core functionalities, including: single-page comprehensive audits (title, meta, canonical, Open Graph, etc.), JSON-LD extraction and validation, robots.txt and sitemap parsing, full-site crawling, and pulling real-user Core Web Vitals from the Chrome UX Report.
The author highlighted two key design decisions:
- Validation follows Google, not Schema.org: Since Schema.org is more permissive, the tool encodes Google Search Central's actual requirements to prevent false positives.
- Context-optimized report truncation: The output is capped on purpose to fit a model's context window rather than for human dashboards. It truncates URL lists per issue category while preserving the true total count, helping the model quickly identify systemic template issues.
