What
Claude Code now has user-facing text explaining that a special lock file can restrict which MCP (Model Context Protocol) servers are allowed to load, limiting things to only the organization's managed servers until the lock file is fixed or removed and Claude Code is restarted.
Why
This makes it clear to users why non-managed MCP servers suddenly stop loading, and tells them what to do about it: fix or remove the lock file and restart.
