AI agents call discord_delete_category to permanently remove resources in MCP-Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a category is an irreversible action that cannot be undone and destroys data (the category structure and potentially associated channels/messages). This meets the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' Severity is high because it affects server structure and can cause loss of organizational context and access control, though it does not…
From the tool's definition Tool name contains 'delete' and description states 'Deletes a Discord category by ID' — this irreversibly removes a category and all its contents.
Documented attack patterns abuse exactly the kind of access discord_delete_category 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_delete_category:
{
"version": "1",
"default": "deny",
"hide": [
"discord_delete_category"
]
}discord_delete_category disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

discord_delete_category is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the discord_delete_category 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_delete_category. 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_delete_category 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.
