Get a list of all Discord servers the bot has access to with detailed information
AI agents call list_servers 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 queries and returns existing data about Discord servers without modifying, deleting, or executing any actions. It is informational only, making it a Read operation with low severity since exposure of server metadata carries minimal risk compared to write, execute, or destructive operations.
From the tool's definition Tool name is 'list_servers' and description states it 'Get a list of all Discord servers the bot has access to with detailed information' — a pure retrieval operation with no side effects.
