What is the LiteSpeed Cache MCP server?
The LiteSpeed Cache MCP server from AcrossAI lets Claude, ChatGPT, Cursor and any other MCP client purge exactly what changed, tune the page cache, CSS, JS and images, and test the object cache on your WordPress site. It runs inside WordPress through the free Abilities Manager and MCP Manager plugins, and works through LiteSpeed Cache itself — with no third-party relay in between.

What your AI can do with LiteSpeed Cache
LiteSpeed Cache has hundreds of settings across page cache, optimisation, images, the crawler and the database. These abilities let an AI assistant purge exactly what changed, tune cache rules and exclusions, adjust CSS, JS and image optimisation, test the object cache, and report the environment — without guessing at option names.
Purge precisely
Purge the whole cache, specific URLs, posts, taxonomy archives or cache tags — not everything every time.
Tune the page cache
Turn caching on or off, set TTLs, vary rules, exclusions and guest mode.
Optimise CSS, JS and images
Adjust minify, combine, lazy load, placeholders and exclusions, and purge generated assets.
Diagnose and maintain
Check cache status, test the object cache, run the crawler, and review database health.
Troubleshooting
Site not showing your latest changes? Three reasons it happens quietly.
Each of these leaves LiteSpeed looking healthy while visitors keep getting an old or broken page.
The page is still cached
A change isn’t live until its page is purged. Purge URLs or Purge Posts clears just what changed.
Optimised CSS or JS is stale
Combined and minified files outlive the edit that should replace them. Purge Generated CSS And JS rebuilds them.
The object cache isn’t connected
Object cache can be switched on while Redis or Memcached isn’t reachable. Test Object Cache Connection checks it.
Try asking
Paste one into Claude, ChatGPT or Cursor once your site is connected.
“Purge the cache for the pricing page.”
“Is LiteSpeed actually caching pages for logged-out visitors?”
“Exclude /checkout/ and /cart/ from the page cache.”
“Turn on lazy loading for images, but not the logo.”
“Is the object cache connected?”
“Which database tables are still using MyISAM?”

LiteSpeed Cache + AI questions
Is there an MCP server for LiteSpeed Cache?
Yes. AcrossAI turns your WordPress site into an MCP server with dedicated LiteSpeed Cache abilities, so Claude, ChatGPT, Cursor or a local model can work with LiteSpeed Cache directly. It’s free on WordPress.org.
Can ChatGPT or Claude manage LiteSpeed Cache?
Yes, once your site is connected over MCP. Ask in plain English and your AI calls the LiteSpeed Cache abilities on this page, with risky changes gated behind an explicit confirm.
Is the LiteSpeed Cache integration free?
Yes. All of its abilities ship in Abilities Manager, which is free on WordPress.org.
Does it need a LiteSpeed server?
The settings and purges work through the LiteSpeed Cache plugin. Page caching itself only serves pages on a LiteSpeed or OpenLiteSpeed server, as with the plugin on its own.
Can the AI see my QUIC.cloud key?
No. Whether a key is present is reported; the key itself is never returned or used.
Which AI assistants work with it?
Any MCP client: Claude, ChatGPT, Gemini, Grok, Cursor, Claude Code, and local runtimes such as Ollama, LM Studio and Open WebUI.
Does my site data pass through AcrossAI’s servers?
No. Your WordPress site runs the MCP server and your AI client connects to it directly. There is no hosted gateway in the middle.
Is AcrossAI affiliated with LiteSpeed Cache?
No. AcrossAI built and maintains this integration independently, using LiteSpeed Cache’s public APIs.
