Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @rankcli/mcp-server
Claude Code 
claude mcp add rankcli -- npx -y @rankcli/mcp-server@0.0.23
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "rankcli": {
            "command": "npx",
            "args": [
                "-y",
                "@rankcli/mcp-server@0.0.23"
            ]

@rankcli/mcp-server

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.

Install

Claude Desktop — download the latest .mcpb from Releases and double-click it. No config file, no terminal.

Claude Code — one line, no config file:

claude mcp add rankcli -- npx -y @rankcli/mcp-server

Anything else (Claude Desktop, Codex, Windsurf) — the standard config block:

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

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

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

Agent skills and Claude Code plugin

The same checks as skills your coding agent loads on demand. Two skills ship in this repo: seo-audit (run the audit, read the JSON, fix the highest-impact issues in the codebase) and seo-ci-gate (fail the build on SEO regressions in GitHub Actions or any CI).

Any agent (Claude Code, Cursor, Codex, Copilot, Windsurf and others), via the skills CLI:

npx skills add integrallis/rankcli-mcp-server

Claude Code plugin (the two skills plus the MCP server, one install):

/plugin install rankcli --marketplace integrallis/rankcli-mcp-server

or from a shell: claude plugin marketplace add integrallis/rankcli-mcp-server then claude plugin install rankcli@rankcli. The skills are then /rankcli:seo-audit and /rankcli:seo-ci-gate.

"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.

Want more?

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:

{
  "mcpServers": {
    "rankcli-hosted": {
      "url": "https://rankcli-audit-worker.fly.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
