Remove a role from a member in a Discord guild. Defaults to dry-run mode.
AI agents call discord.role.remove to permanently remove resources in Discord MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a role from a member revokes their permissions and access within the guild. While technically reversible (the role can be re-added), role removal is a deletion-type operation that falls under Destructive. Misuse could strip members of critical roles (admin, moderator) causing significant access disruption.
From the tool's definition 'Remove a role from a member in a Discord guild' — removes an assigned role, which is a reversible action but constitutes removal/deletion of a permission/access grant. However, 'Defaults to dry-run mode' suggests some safety net.
Documented attack patterns abuse exactly the kind of access discord.role.remove gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Discord MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for discord.role.remove:
{
"version": "1",
"default": "deny",
"hide": [
"discord.role.remove"
]
}discord.role.remove disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
