Claude Code can now skip subscribing to an MCP server's list-change notifications.
What's wrong with this entry?
Anonymous. No account, no email.
What
On a successful MCP connection the client no longer always subscribes to list-changed notifications. For servers on the modern protocol the subscription can be skipped, and a log line records that change-notification delivery is off for that connection.
Details
- The skip is decided by a denylist consulted at connect time; nothing in the CLI's own settings populates it, so which servers are affected is decided outside this build.
Evidence
subscriptions/listen suppressed by the listen denylist; list_changed delivery is off for this connection
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
