Security Report
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. Three things an AI agent (or a
human) can do with it:
- Scan the app you're building — FREE, no account —
siteglass_scan_localruns a headless browser on your machine againsthttp://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_renderrenders 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.
