Siteglass

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

1. 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.)
2. Web-QA an app you built — register → verify → scan → generate flows → run → read results, autonomously, no human signup.

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; after that, 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_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.
