Create a new application (slash) command. Command names must be lowercase, contain no spaces, and be 1-32 characters.
AI agents use create_command 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 creates a new slash command in Discord, which is a reversible action. The command can subsequently be modified or deleted. While this affects Discord server functionality and could enable unintended bot behaviors if misused, it does not irreversibly destroy data (Destructive), execute arbitrary code (Execute), or move money (Financial).
From the tool's definition Tool description states 'Create a new application (slash) command', indicating creation of a new entity that can be modified or deleted later.
Documented attack patterns abuse exactly the kind of access create_command 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 create_command:
{
"version": "1",
"default": "deny",
"tools": {
"create_command": {
"limits": [
{
"counter": "create_command_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_command 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.

Create a new application (slash) command. Command names must be lowercase, contain no spaces, and be 1-32 characters. 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 create_command: 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.
create_command 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 create_command 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 create_command. 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.
create_command 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.
Free to start. No card required.
