Delete a list.
AI agents call delete_list to permanently remove resources in RTM MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a list is an irreversible operation that removes an entire collection of tasks and associated data. This falls squarely into the Destructive category because the action cannot be undone (despite the server mentioning 'undo support' elsewhere, the tool description does not indicate undo capability for this specific deletion).
From the tool's definition Tool name: 'delete_list'. Description: 'Delete a list.' The verb 'delete' combined with 'list' indicates irreversible removal of a data structure that may contain multiple tasks and notes.
Attacks that exploit this kind of access
Delete a list. It is categorised as a Destructive tool in the RTM MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RTM MCP Server MCP server in PolicyLayer and add a rule for delete_list: 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 RTM MCP Server. Nothing to install.
delete_list 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 delete_list 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 delete_list. 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.
delete_list is provided by the RTM MCP Server MCP server (ljadach/rtm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
