Lists all forum channels in a specified Discord server (guild)
AI agents call discord_get_forum_channels to retrieve information from MCP-Discord without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing forum channels without modifying, creating, deleting, or executing any actions. It is a straightforward data retrieval operation, placing it squarely in the Read category. Severity is low because listing channel metadata poses minimal risk even if misused by an agent; the blast radius is confined to information disclosure of public or semi-public Discord server structure.
