WHAT IT DOES

What apps_event_authorizations_list does on Slack

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

RISK

Why apps_event_authorizations_list is rated Low

The tool appears to retrieve or enumerate event authorizations for apps, which is a read operation with no side effects. Severity is medium rather than low because authorization data is sensitive and could reveal security posture or app permissions if exfiltrated by a compromised agent.

From the tool's definition Tool name 'apps_event_authorizations_list' indicates a listing/retrieval operation on authorization data. The 'list' suffix and context within Slack's API families suggest querying existing authorizations rather than modifying them.
