WHY IT NEEDS A POLICY

Why appflowy_refresh_token needs a policy

This tool modifies authentication state by issuing a new access token. While not destructive (the operation is reversible and issued tokens eventually expire), it is a Write operation because it creates/updates credentials. Severity is medium because misuse could allow an attacker to maintain persistence by refreshing a stolen token, but the operation itself is part of normal OAuth flows.

From the tool's definition Tool updates access credentials via 'Refresh access token using refresh token' — a state change operation that modifies or rotates authentication tokens.
