List channels in a Discord guild (server). Optionally filter by channel type.
AI agents call list_channels to retrieve information from Discord MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries channel information from a Discord guild without creating, modifying, deleting, or executing anything. It is a pure read operation with minimal blast radius if misused—an agent could only enumerate channels, which is non-destructive reconnaissance.
From the tool's definition Tool name 'list_channels' and description explicitly state it 'List channels in a Discord guild'. The verb 'list' is a read-only retrieval operation with no side effects. No modification, deletion, or execution is indicated.
