Crawlinx MCP

> Free technical-SEO audit as an MCP server — built for AI coding agents.

Crawlinx is a hosted Model Context Protocol server that lets your AI agent audit a website's technical SEO and act on the results. It crawls a site (50 pages by default, up to 200 via `max_pages`), runs 156 technical-SEO checks, and returns an LLM-ready Markdown report with a prioritized fix plan — small enough to keep in context on a real site.

• ☁️ Remote server over Streamable HTTP — no local install, no API key, no signup
• 🔎 156 checks — titles, meta, canonicals, orphan pages, noindex, internal PageRank, JS render-diff, images, performance, sitemap
• 🤖 Agent-native — compact reports, per-issue drill-down, and scan diffs so an agent can scan → fix → verify in a loop
• 🔗 Public shareable reports — every scan has a URL

Install

The server is remote — you only need the endpoint `https://crawlinx.com/mcp`. No key.

Claude Code

claude mcp add --transport http crawlinx https://crawlinx.com/mcp

Cursor / Windsurf / Cline / Claude Desktop

Add to your MCP config (`mcp.json` / settings):

{
  "mcpServers": {
    "crawlinx": {
      "type": "http",
      "url": "https://crawlinx.com/mcp"
    }
  }
}

A machine-readable manifest is served at `/.well-known/mcp.json`.

Tools

Example prompts

• *"Audit https://example.com and give me the top 5 SEO fixes."*
• *"Scan my site, then fix the duplicate `` issues in the codebase and re-scan to confirm."*
• *"Which pages are orphaned (no internal links) and how do I link them?"*

Typical workflow

1. `scan_url` → get a `scan_id`

2. poll `get_report_markdown` until the crawl finishes

3. `get_issue_detail(scan_id, code)` to expand a specific issue before changing code

4. apply fixes

5. re-scan, then `diff_scan(scan_id)` to verify

The crawler

Audits run as `CrawlinxBot`, which honors `robots.txt`, limits request rates, and does not bypass access controls. See crawlinx.com/bot. Site owners can opt out via robots.txt or the removal form.

Maintenance & rankings

This MCP is a living product — aggregators (Smithery Quality Score, polygraph.so security grades, MCP Bench) actively rank and grade it, and the Official Registry cascades our listing everywhere. Keep the endpoint healthy and re-publish on changes. See **MAINTENANCE.md**.
