Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "siteglass": {
      "command": "npx",

        "SITEGLASS_BASE_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add siteglass --env SITEGLASS_API_KEY=your-value --env SITEGLASS_BASE_URL=your-value -- npx -y siteglass-mcp

Fill in the empty values before running it.

Common questions

Is Siteglass MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SITEGLASS_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.5) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

siteglass MCP server

siteglass-mcp exposes siteglass.io as MCP tools. Three things an AI agent (or a human) can do with it:

Scan the app you're building — FREE, no account — siteglass_scan_local runs a headless browser *on your machine* against http://localhost:PORT (or any URL you can reach — nothing is tunneled to us), then siteglass analyzes the crawl and returns real findings: broken links/assets, console errors, accessibility & SEO issues, forms worth testing, plus a plain-English report. Point it at your dev server right after the agent builds or changes the app. No signup, no ownership verification, no payment. (First run downloads a headless Chromium, ~1 min.)
Archive any public URL — siteglass_render renders a page server-side and returns a permanent, shareable snapshot: an interactive rrweb DOM capture (post-JS, selectable text, working links), a single-page PDF, or a full-page PNG. No CAPTCHA, no signup, no ownership check, callable programmatically — a bot-friendly alternative to archive.today. (It renders JS-heavy pages; it does *not* produce WARC, and if the target itself blocks datacenter IPs the capture can come back empty.)
Web-QA a deployed site you own — register → verify → scan → generate flows → run → read results, autonomously, no human signup. This is the hosted/continuous tier (runs on our servers against your live site).

The local scan (1) is free and needs no auth. For the hosted tools (2, 3), auth is automatic (creates + caches an API key at ~/.siteglass/key; set SITEGLASS_API_KEY to use your own); the first scan per site is free, then scans (2 credits) and flow runs (1 credit) draw from a prepaid balance topped up in USD over Bitcoin Lightning.

Install

npx siteglass-mcp

Claude Code:

claude mcp add siteglass -- npx siteglass-mcp

Cursor / Claude Desktop / Windsurf — add to the MCP config (~/.cursor/mcp.json, claude_desktop_config.json, …):

"mcpServers": { "siteglass": { "command": "npx", "args": ["-y", "siteglass-mcp"] } } }

OpenClaw — add to ~/.openclaw/openclaw.json (OpenClaw consumes MCP servers); your assistant gets the siteglass_* tools:

{ "mcpServers": { "siteglass": { "command": "npx", "args": ["-y", "siteglass-mcp"] } } }

Then ask the agent: *"test my app at with siteglass."*

Tools

tool	does
`siteglass_scan_local`	free, no-auth — crawl a local/dev app in a browser on your machine → analyzed findings + report
`siteglass_render`	archive any public URL → shareable snapshot permalink (rrweb / pdf / png); no CAPTCHA, no signup
`siteglass_get_render`	fetch an archive once its Lightning invoice is paid
`siteglass_register_site`	register an app URL, get an ownership-proof token
`siteglass_verify_site`	confirm the token is live (DNS TXT or hosted)
`siteglass_scan` / `siteglass_get_scan`	crawl the site → report + findings (first scan free)
`siteglass_generate_flows`	derive executable E2E test flows from a scan
`siteglass_run_flow` / `siteglass_get_run`	run a flow → per-step pass/fail, screenshots, video, rrweb replay
`siteglass_set_credentials`	give a test login for authenticated flows
`siteglass_feedback`	send feedback to the siteglass team

Long ops return an id and you poll the get_* tool, so every call stays under MCP client request timeouts.
