With the free edition of Zinn® Cache, a connected AI agent can use 6 abilities (see Zinn® Cache: connect an AI agent (MCP) for how to connect). The same abilities are available over the WordPress REST API.
What the free edition lets an agent do
Read the diagnostics report; Read the cache settings; Read the cache status; Purge the cache; Put the cache settings back to their defaults; Change the cache settings.
Try asking your AI app, for example: "list my pages", or "what can you do on my site with Zinn® Cache?" — it reads the list above from your site and picks the ability itself.
