Lists members in a Discord server with their roles
AI agents call discord_list_members 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 retrieves existing data (member list and role information) without creating, modifying, deleting, or executing anything. It is a passive information retrieval operation, making it a Read category risk. The severity is low because listing members is typically non-sensitive in most Discord contexts and does not affect system state or enable harmful actions directly.
From the tool's definition Tool name is 'discord_list_members' and description states it 'Lists members in a Discord server with their roles' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access discord_list_members 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_members:
{
"version": "1",
"default": "deny",
"tools": {
"discord_list_members": {}
}
}discord_list_members is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists members in a Discord server with their roles. It is categorised as a Read tool in the MCP-Discord MCP Server, which means it retrieves data without modifying state.
Register the MCP-Discord MCP server in PolicyLayer and add a rule for discord_list_members: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP-Discord. Nothing to install.
discord_list_members is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the discord_list_members rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for discord_list_members. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
discord_list_members is provided by the MCP-Discord MCP server (barryyip0625/mcp-discord). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP-Discord, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
