Overview

AI-generated overview

A local MCP server that audits websites for accessibility, performance, SEO, design quality and mobile responsiveness, returning scores, grades and prioritized,

What you can do
Run a full audit of a site across accessibility, performance, SEO, design and mobile, with scores, grades and prioritized fixes. Get a fast score-and-grade triage of a page. Run a WCAG 2.1 AA accessibility audit with criterion references and an EAA compliance status. Analyze performance, SEO metadata and structured data separately. Compare two URLs side by side.
When to use it
Useful when you want an assistant to check a website's accessibility and EAA/WCAG status, performance, SEO or mobile readiness, or to compare two sites before a redesign or compliance review.
Requirements
Runs as a local process over stdio; the README installs it with Node.js by pointing the MCP config at the built index.js file, or building from source with npm. No authentication, environment variables or headers are declared. Audits target live websites, so network access is implied.
Before you install
The server fetches the URLs you give it, so audited pages are requested from the user's machine. Results are automated checks and scores, not a substitute for manual accessibility testing or legal compliance advice. The README's compliance framing is marketing context, not a guarantee.

Installation

In SourceWeft

  1. Open Siteaudit 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.

40% 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.
