AI agents call discord_delete_message to permanently remove resources in Sage MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Message deletion is an irreversible action that destroys data. Once deleted, the message cannot be recovered through normal means. This meets the definition of Destructive category (deletes data that cannot be undone).
From the tool's definition Tool name is 'discord_delete_message' and description states 'Delete a message from a channel'. The verb 'delete' combined with the irreversible nature of message deletion clearly indicates a destructive operation.
Documented attack patterns abuse exactly the kind of access discord_delete_message gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for discord_delete_message:
{
"version": "1",
"default": "deny",
"hide": [
"discord_delete_message"
]
}discord_delete_message disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a message from a channel. It is categorised as a Destructive tool in the Sage MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sage MCP server in PolicyLayer and add a rule for discord_delete_message: 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 Sage MCP. Nothing to install.
discord_delete_message 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_message 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_message. 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_message is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
