Siteaudit Mcp

SEO, performance, and security audits for any URL — no API keys required

Overview

AI-generated overview

Audits any website URL for SEO, performance, and security issues, returning scores and prioritized fixes.

What you can do
SiteAudit exposes eight tools that fetch a target URL and analyze its HTML and HTTP headers. Tools cover full audits with a unified 0-100 score, SEO checks (titles, meta, headings, structured data, Open Graph), security headers and SSL certificate checks, performance metrics, multi-site comparison, Google PageSpeed Insights Lighthouse scores, broken link crawling, and robots.txt parsing.
When to use it
Useful when you want an assistant to inspect a live site you own or are reviewing: checking SEO metadata, security headers, response times, broken links, or comparing several sites side by side. It is aimed at developers and site owners doing quick audits without a paid SEO subscription.
Requirements
Runs as a local process over stdio, installed from PyPI as siteaudit-mcp (for example via uvx or pip), so Python and network access to the target sites are needed. No API keys or environment variables are declared. The README also describes a hosted endpoint and paid tiers, but the manifest declares only the local stdio package.
Before you install
The server fetches whatever URLs it is given, so audit only sites you are authorized to test. The README mentions a hosted option, paid plans, and a Google PageSpeed Insights API; using those sends the audited URL to third parties. Self-hosting means you manage updates and any PageSpeed quota yourself.

Installation

In SourceWeft

  1. Open Siteaudit Mcp 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.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

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.
