Free, local SEO + GEO (AI-search-citation) analysis as an MCP tool. No signup, no API key, nothing sent to RankCLI's servers — it runs entirely inside your MCP host (Claude Code, Claude Desktop, Cursor, etc.) against HTML you already have or that your host fetches for you.
Claude Desktop — download the latest .mcpb from
Releases and double-click it.
No config file, no terminal.
Claude Code — one line, no config file:
Anything else (Claude Desktop, Codex, Windsurf) — the standard config block:

Just ask Claude:
"Run an SEO audit on https://example.com"
Your MCP host fetches the page and Claude calls these tools directly — nothing round-trips through RankCLI.
This local server works from HTML/robots.txt you or your MCP host supply. For URL-only tools that fetch and crawl for you (seo_audit, seo_geo_check, seo_robots_check, seo_compare), plus the newer Cloudflare AI-crawler-gating compliance check, CI/CD scheduling, and auto-fix PRs, see the hosted endpoint and paid tiers:
