- ✓xSpeed Cache installedDetected — update xSpeed to report its version here
- ✓MCP server connectedLive — your AI assistant can control the cache
- →xSpeed Hub attachedOptional: manage all your sites from one MCP connection at app.xspeedcache.com (this xSpeed version does not report Hub status).
8 of these checks map to an xSpeed feature. 911appliance.com's xSpeed MCP server is live — paste this into Claude (or any MCP client) connected to it:
Connect to my site's xSpeed MCP server, read the failing checks from https://xspeedcache.com/scan/r/911appliance-com-967d7b3643.md, and apply the fixes: enable page caching, compression, minification and lazy loading, warm the cache, then run a benchmark and re-scan at https://xspeedcache.com/scan to confirm the score improved.Hosting is the other half.
xSpeed makes any host faster, but a cache is only as fast as the server behind a MISS.
xCloud — managed hosting from the team behind xSpeed — gives the cache an origin tuned for it, with agent/MCP access built in and bring-your-own-server pricing.
