What
When an MCP tool call fails, Claude Code has logic to clear the cached connection and retry once. This retry used to trigger on a generic boolean condition, but now it only triggers when the failure reason is specifically credential_rejected.
Why
This makes the reconnect-and-retry behavior more precise, so Claude Code only clears and retries the connection when the failure was actually a credential rejection, rather than any other kind of failure.
