What
When a session is started with the --project-config-root flag, Claude Code now blocks two things:
adding or removing project-scope MCP servers (connections to Model Context Protocol tool servers)
creating durable scheduled tasks
Both now throw an error directing the user to use the local or user scope instead.
Why
This prevents project-scope changes that wouldn't make sense or wouldn't be reliably saved when the session's project config root has been overridden, pointing users to a scope that will work correctly instead.
