Lists all Discord servers (guilds) the bot has access to
AI agents call discord_list_guilds 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 performs a read-only query of Discord guild metadata. It retrieves information about servers the bot can access but does not create, modify, delete, or execute any actions.
From the tool's definition Tool name is 'discord_list_guilds' and description states 'Lists all Discord servers (guilds) the bot has access to' — a retrieval operation with no side effects.
