What
The MCP reconnect and status summary the model sees gained a Cached line alongside Connected, Failed and Still connecting.
Details
- The line explains that those servers' tools can be called now and that the connection is made lazily on first call.
- Subject to the same discovery-cache gate as the cached state; the list is empty when no cached servers exist.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
