MCP calls that create shared items can be retried after your approval

MCP servers are programs that give Claude extra tools. Two things are different when Claude calls them:

• A call that fails because it did not say who a new item should be shared with, and that carries a sharing value, is retried with that value set. The retry always shows you an approval prompt first, and if Claude Code cannot run its safety check the call is refused.
• A session with no working folder now refuses calls that use a relative path (a path that only makes sense from a starting folder), with a message saying it cannot check the call against its permission rules.
