unarchive_dialog · Claudegram MCP: Risk & Policy

WHAT IT DOES

What unarchive_dialog does on Claudegram

AI agents use unarchive_dialog to create or update resources in Claudegram — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claudegram environment.

WHY IT NEEDS A POLICY

Why unarchive_dialog needs a policy

The tool changes the folder/organizational state of a Telegram dialog but does not delete data or execute external code. It is reversible (can be re-archived), making it a Write action rather than Destructive. The severity is medium because misuse could reorganize a user's chat structure, creating confusion or visibility of private conversations, but the action is easily undone.

From the tool's definition Tool description states 'Вернуть диалог из архива в основной список (folder=0)' — translates to 'Return dialog from archive to main list' — which modifies the state/organization of a chat dialog by moving it from archived status to active status.
