Remove a role from multiple members at once. Member names are fuzzy-matched.
AI agents use bulk_remove_role to create or update resources in Discord — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord environment.
This tool modifies role assignments for multiple Discord members simultaneously. While role removal is reversible (roles can be re-assigned), doing so in bulk amplifies the blast radius significantly — an AI agent could accidentally strip critical roles (e.g., admin, moderator) from many members at once.

Documented attack patterns abuse exactly the kind of access bulk_remove_role gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Discord, and nothing reaches the server without passing your rules. This is the rule we recommend for bulk_remove_role:
{
"version": "1",
"default": "deny",
"tools": {
"bulk_remove_role": {
"limits": [
{
"counter": "bulk_remove_role_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}bulk_remove_role stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Remove a role from multiple members at once. Member names are fuzzy-matched. It is categorised as a Write tool in the Discord MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Discord MCP server in PolicyLayer and add a rule for bulk_remove_role: 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 Discord. Nothing to install.
bulk_remove_role is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the bulk_remove_role 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 bulk_remove_role. 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.
bulk_remove_role is provided by the Discord MCP server (hardheadhackerhead/discord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Discord, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
