What

Some MCP servers, outside programs that give Claude extra tools, send their replies over a stream that stays open. Claude Code now keeps track of which requests on each stream are still waiting for an answer. Once all of them are answered, it can end that stream.

Why

This may stop Claude Code waiting on a stream that the server never closes.
