AI agents call cancel_account to permanently remove resources in Linode MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Account cancellation is a destructive action that permanently removes the account and its data from the system. This is irreversible and represents the highest severity of destructive operations—an AI agent with access to this tool could terminate the entire cloud infrastructure account without recovery options.
From the tool's definition Tool name 'cancel_account' combined with description 'Cancel your account' indicates irreversible termination of the Linode account, which cannot be undone and results in loss of all associated resources, data, and services.
Documented attack patterns abuse exactly the kind of access cancel_account gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for cancel_account:
{
"version": "1",
"default": "deny",
"hide": [
"cancel_account"
]
}cancel_account disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Cancel your account. It is categorised as a Destructive tool in the Linode MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for cancel_account: 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 Linode MCP Server. Nothing to install.
cancel_account 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 cancel_account 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 cancel_account. 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.
cancel_account is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Linode MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
