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.

npx @rankcli/mcp-server

Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "rankcli": {
      "command": "npx",
      "args": ["@rankcli/mcp-server"]
    }
  }
}

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:
