Deletes a specific message from a Discord text channel
AI agents call discord_delete_message 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.
This tool permanently removes data (Discord messages) that cannot be recovered. While the blast radius is limited to a single message and requires valid channel/message IDs, message deletion is an irreversible destructive action. Classified as Destructive rather than Execute because the operation itself (deletion) is the primary effect, not command execution with variable outcomes.
From the tool's definition Tool name explicitly states 'delete_message' and description confirms it 'Deletes a specific message from a Discord text channel'. Deletion is irreversible.
Attacks that exploit this kind of access
Deletes a specific message from a Discord text channel. It is categorised as a Destructive tool in the MCP-Discord MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP-Discord 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 MCP-Discord. 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 MCP-Discord MCP server (jar285/mcp-discord). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
