What
Claude Code can pre-approve certain tools so they run without asking you for permission. Some of these pre-approvals are meant only for a conversation thread. The part of Claude Code that handles project replies over the bridge connection used to pre-approve every tool on its auto-allow list. It now watches the list of MCP tools (tools supplied by outside programs). When those tools do not belong to a thread, it holds back the thread-only pre-approvals and logs a note saying so.
The approval rules are also applied as soon as this reply handler starts, rather than later.
Why
Fewer tools get automatic permission in this path, so some may now ask before they run.
