What
An MCP server (a connected tool provider that extends Claude Code) can send an 'elicitation' request, which asks the user for input mid-task. The handler that answers these requests now enforces per-connection limits:
a maximum number of outstanding elicitations at once
a maximum number admitted per minute
a maximum size for the serialized request, measured with a new size estimator
Requests that exceed any of these limits are refused or cancelled instead of being processed.
Why
This prevents a misbehaving or overly chatty MCP server from flooding you with input requests or sending oversized ones.
