 :::info What's happening?
 
-ToolHive downloads the container image for the fetch server (if you don't
-already have it), creates a container with the appropriate security settings,
-and starts the server. It also sets up a proxy that lets your AI agent
-communicate with the server.
+When you run an MCP server, ToolHive:
+
+- Verifies the MCP server image provenance (if attestation information is
+  available in the registry)
+- Downloads the container image
+- Sets up the container with the necessary security settings and starts it in
+  the background
+- Sets up a reverse proxy that lets your AI client applications communicate with
+  the server
