Unclear The finding does not say what the shared wrapper actually does to the handlers.
What
Internally, the three handlers Claude Code registers for MCP (Model Context Protocol, the standard it uses to talk to external tool servers) notifications — for changes to a server's tools, prompts, and resources lists — are now all wrapped by the same helper function before being registered, instead of each being passed through directly.
Why
This is an internal consistency change with no described effect on what these notifications do; it likely centralizes some shared handling logic across the three cases.
