What happens when Claude tries to access a file outside approved roots?

When Claude attempts to access a file path that falls outside the approved root directories, the server's path validation function should reject the request and return an error. Claude can then inform the user that the requested file is not accessible from the current server configuration and suggest adding the relevant directory as a root. This clear feedback loop helps users understand why a request failed and how to fix it, rather than silently failing or returning confusing error messages about missing files. ---
