Website health analysis: SEO, accessibility, performance, security, and broken links

VerifiedSTDIODesktop onlyWeb Search & ScrapingDeveloper Tools

Overview

AI-generated overview

A local MCP server that lets an AI assistant audit any website for SEO, accessibility, security headers, performance and broken links.

What you can do
Run a full website health check covering SEO score, performance, security headers and image analysis on a URL. Audit SEO in depth: title, meta tags, heading hierarchy, content quality, Open Graph and structured data. Scan accessibility: alt text, ARIA landmarks, heading order and form labels. Crawl a page's links and report 404s, timeouts and redirects. Compare two URLs side by side across SEO and performance metrics.
When to use it
Useful when you want an assistant to audit your own site or a competitor's page, find dead links before publishing, check accessibility on a landing page, or compare two pages' SEO and performance without leaving the chat.
Requirements
Runs locally as a stdio process, typically launched with npx from the npm package webcheck-mcp, so Node.js and network access are needed. No API keys, accounts or configuration are required.
Before you install
The assistant fetches the URLs you give it over HTTP, so target sites see requests from your machine; avoid pointing it at internal or private addresses. The README advertises a paid industry template pack (about ¥9.9) as an optional extra; the analysis itself is described as free and complete. No data is said to be sent to third-party analytics.

Installation

In SourceWeft

  1. Open Webcheck in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
