What
Errors sent back over the MCP bridge that quote a server name (server not found, no OAuth flow in progress, the Anthropic-hosted rejection, managed-policy and disabled-session messages) now pass the name through a helper before inserting it. It looks like escaping of untrusted names, but the helper is minified and its exact behaviour is not identifiable from the build.
Evidence
MCP controls aren't available right now \u2014 the terminal is still starting up or is showing another view
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
