AI agents may call sudo_session to permanently remove or destroy resources in Defense MCP. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call sudo_session in a loop, permanently destroying resources in Defense MCP. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.
Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access sudo_session gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Sudo: elevate privileges, check/drop/extend session, preflight tool checks. It is categorised as a Destructive tool in the Defense MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Defense MCP server in PolicyLayer and add a rule for sudo_session: 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 Defense MCP. Nothing to install.
sudo_session 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 sudo_session 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 sudo_session. 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.
sudo_session is provided by the Defense MCP server (bottobot/defense-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
