Lists all Discord servers the bot is a member of
AI agents call discord_list_servers 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 queries and returns information about servers without modifying, creating, deleting, or executing any actions. It is a straightforward read operation with minimal risk—an AI agent misusing it would only retrieve metadata about server membership, posing no security, data integrity, or operational threat.
From the tool's definition Tool name 'discord_list_servers' and description 'Lists all Discord servers the bot is a member of' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access discord_list_servers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-Discord, and nothing reaches the server without passing your rules. This is the rule we recommend for discord_list_servers:
{
"version": "1",
"default": "deny",
"tools": {
"discord_list_servers": {}
}
}discord_list_servers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
