Under the hood
MCPB plugin bundle file paths are now sanitized before appearing in logs or error messages
What
When Claude Code loads an MCPB (a packaged Claude plugin bundle), the source path is now passed through a sanitizer before it shows up in logs or error text. A local file read failure now produces a distinct 'MCPB local file read failed' error that shows the sanitized display path instead of the raw resolved file path.
Why
This avoids leaking potentially sensitive local file path details into logs and error messages while still giving a usable, readable path for troubleshooting.
