WHY IT NEEDS A POLICY

Why gdrive_add_account needs a policy

This tool creates/establishes a new authenticated account connection, which is a state-modifying operation but reversible (the account can be removed). It doesn't read, execute code, delete data, or move money. While it has security implications (granting API access), it is fundamentally a Write operation that creates a new authorization relationship.

From the tool's definition Tool generates an authorization URL to 'add a new Google account', which establishes a new authentication credential and modifies the system's account configuration state.
