WHAT IT DOES

What open_slack_dm does on Freshdesk

AI agents call open_slack_dm to retrieve information from Freshdesk without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why open_slack_dm is rated Low

This tool only retrieves or opens a DM channel identifier; it does not send messages or create any persistent data. It is purely a lookup/read operation that returns a channel ID for subsequent use.

From the tool's definition 'Open or get the DM channel with a user by their Slack User ID' and 'Does NOT send a notification' — returns the DM channel ID for use with post_slack_message

Attacks that exploit this kind of access

open_slack_dm Allowed
