| description | Test a URL's uptime, reliability, and performance from real devices across geographic regions. Use when the user wants to check if a site is up, how fast it loads worldwide, Core Web Vitals, or to verify a deployment from different regions. |
UpRock: Sweep (global uptime & performance)
Load a URL from real devices in multiple regions at once and report reliability + performance. Great right after a deploy, or to see how a site performs for users around the world.
How to do it
-
Call the uprock MCP tool sweep with:
url: target URL (required).regions: subset of NA, EU, APAC, LATAM, MEA. Default [NA, EU, APAC] (fastest, most reliable pools). Add LATAM/MEA when the user cares about those markets.device: mobile (default) or desktop.tries: checks per region (default 5). All checks run concurrently.timeout: overall seconds (default 60); total wall-clock ≈ this value.
-
Each completed check returns Core Web Vitals (TTFB, FCP, LCP, CLS), load time, transfer size, and HTTP protocol. The response includes a report_url (shareable human-readable report) and screenshots as sweep:// resource URIs.
-
Summarize for the user:
- Up/down per region and the
failed_jobs count (inspect per-job error fields for failures).
- Performance per region (highlight slowest regions / poor LCP or CLS).
- Share the
report_url.
- If they want to see a region's render, call
resource_fetch on a sweep://…/screenshot URI.
Notes
- A sweep can partially succeed; always report how many checks failed and why.
- For reading a page's content (not measuring it), use
/uprock:scrape.
