search_modules_channels

What search_modules_channels does on Slack

AI agents call search_modules_channels 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.

Why search_modules_channels is rated Low

This tool retrieves information about channels matching given criteria. It does not create, modify, delete, or execute any actions — it only returns matching results. The 'undocumented session endpoint' notation indicates it accesses Slack's internal API but does not change the nature of the read-only operation. Severity is low because channel name/topic enumeration poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name contains 'search' and description states 'Search channels by name or topic' — a query operation with no side effects.
