Librecrawl — Technical SEO Audit MCP Server

Sitewalk: technical SEO audit MCP server

Ask your AI assistant to audit a website. Get the technical SEO problems back, ranked by impact, with a plain fix for each.

---

This repository is the Sitewalk MCP server and nothing else: a Python server that drives the open-source LibreCrawl crawler, runs 30+ technical SEO checks, and hands your AI assistant a ranked report plus a zip of PDF and CSVs. It runs on your own machine, with no account, no sign-in and no page cap. Nothing leaves your machine except the requests the crawler makes to the site you audit.

Prefer not to host anything? The same audit is available as an app inside ChatGPT.

Set it up on your machine

You need Docker running. Then:

git clone https://github.com/adityaarsharma/sitewalk.git

cd sitewalk ./setup.sh

The script checks your machine, asks one optional question (a Google PageSpeed key), builds and starts the stack, waits until the MCP server answers, and prints exactly how to connect your assistant. The first build takes a few minutes.

Without Docker, see the manual route in docs/GETTING-STARTED.md.

Connect an assistant

The server listens on http://127.0.0.1:5081/mcp (streamable HTTP).

• ChatGPT and Grok reach servers over the internet, so they need a public https address that forwards to your machine. The server has no sign-in of its own, so put it behind a tunnel that adds access control. Steps in docs/GETTING-STARTED.md.
• Clients on your computer (Codex, Windsurf, any stdio-only client) connect through mcp-remote:

{

"mcpServers": { "sitewalk": { "command": "npx", "args": ["-y", "mcp-remote", "http://127.0.0.1:5081/mcp"] } } }

Then ask: Audit https://yoursite.com for technical SEO problems.

What you get

• 30+ checks per audit (broken links, redirects, canonicals, titles and descriptions, headings, schema, images, hreflang, sitemap gaps, and more). Full list and the nine report files: docs/CHECKS.md.
• A branded PDF, a Markdown copy and CSVs, zipped in ./reports.
• Chunked crawling that does not time out, WAF challenge detection, and a crawl delay that adapts to the site.
• 38 MCP tools: docs/TOOLS.md.
