Security Report

5.2

Moderate5.2Moderate Risk

The siteglass MCP server is a well-structured tool for web QA and archiving with appropriate authentication and reasonable permissions. The server auto-generates and caches API keys securely, uses proper Bearer token authentication, and makes only expected network calls to the siteglass.io API. Minor code quality issues around error handling and lack of input validation on URLs do not significantly impact security posture. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

siteglass MCP server

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

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 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.
