Lists all roles in a Discord server with their properties
AI agents call discord_list_roles 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 only retrieves and enumerates existing role data from a Discord server. It performs a query operation ('list') that returns information without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an AI could only learn about role structure, not alter permissions or access control.
From the tool's definition Tool name is 'discord_list_roles' and description states 'Lists all roles in a Discord server with their properties' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access discord_list_roles 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_roles:
{
"version": "1",
"default": "deny",
"tools": {
"discord_list_roles": {}
}
}discord_list_roles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lists all roles in a Discord server with their properties. 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_roles: 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_roles 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_roles 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_roles. 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_roles 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.
