import_contacts · Claudegram MCP: Risk & Policy

WHAT IT DOES

What import_contacts does on Claudegram

AI agents use import_contacts 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 import_contacts needs a policy

The tool creates or modifies contact data within Telegram by importing phone numbers as contacts. This is a Write-category action: it adds new data to the system reversibly. Severity is medium because while contacts are personal data and bulk import could be misused to pollute the contact list or enable social engineering, the operation doesn't delete data, execute code, or move money.

From the tool's definition Tool description states 'Массовый импорт контактов' (bulk import contacts) — a write operation that creates contact entries in the user's Telegram account. This is reversible through deletion, distinguishing it from destructive operations.
