What
The per-server complete_authentication tool generated for MCP servers is now tagged isAuthStub in its metadata, so callers can tell it apart from the server's real tools. On success it now builds its confirmation message from the server name plus the tools actually available, instead of the old fixed line claiming the server's tools should now be available.
Evidence
isAuthStub
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
