RenderAudit MCP Server

Let Claude (or any MCP-compatible agent) run a real, browser-rendered website audit — without leaving the chat.

RenderAudit renders your page in headless Chromium, the same engine behind Chrome, and checks for problems that source-code-only tools miss: invisible text, WCAG contrast failures verified pixel-by-pixel, broken links, and 14 checks in total. The MCP server exposes this to any MCP-compatible AI agent.

Tools

scan_website(url) Free scan

Actually runs a live scan on any public URL and returns a plain-English summary: score out of 100, findings by severity, what passed, and an honest read on whether the full report is worth it for that particular site. This is the only tool that performs a scan — it's the same free tier available on the site, nothing paid is unlocked here.

get_full_report_info(url) Info only

Explains what the $15 full report includes and returns the checkout link. Doesn't generate or charge anything — purchasing and report generation both happen on the website (pay first, then submit your URL on the page you're redirected to), so this tool never triggers report generation for free.

Setup (Windows / PowerShell)

1. Open PowerShell anywhere and install dependencies:

pip install mcp requests

2. Download the server script:

curl -o mcp_server.py https://renderaudit.com/static/mcp_server.py

3. Add it to Claude Desktop. Open (or create) this file:

notepad "$env:APPDATA\Claude\claude_desktop_config.json"

4. Paste this in (merge into mcpServers if the file already has other servers, update the path to wherever you saved mcp_server.py), save, then fully quit and reopen Claude Desktop:

{
  "mcpServers": {
    "renderaudit": {
      "command": "python",
      "args": ["C:\\path\\to\\mcp_server.py"]
    }
  }
}

No API key, no email setup, no credentials of any kind needed — the server only talks to the public scanner and checkout link at renderaudit.com.

Test it

In a new Claude Desktop chat, check the tools icon in the input box — renderaudit should be listed with scan_website and get_full_report_info.
Ask Claude: "Use RenderAudit to scan renderaudit.com" — confirm it returns a score, findings, and a verdict.
Ask Claude: "What does RenderAudit's full report include?" — confirm it explains the $15 report and shows the checkout link.

Why this exists

Most site owners never think to check what a browser actually renders — only what's in the source. If you're already talking to Claude about a site (yours, a client's, a competitor's), you can now get a real audit in the same conversation instead of switching tabs.
