AI agents call delete-todo to permanently remove resources in Todo List MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of data is irreversible and represents the most severe category applicable. Although the blast radius is limited to individual todo items rather than a full database wipe, the destructive nature and inability to undo the operation justifies 'high' severity. Confidence is high because the intent is explicit and unambiguous.
From the tool's definition Tool name 'delete-todo' with description 'Delete a todo' indicates irreversible removal of data. The action cannot be undone and permanently removes a todo item from the system.
Documented attack patterns abuse exactly the kind of access delete-todo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Todo List MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-todo:
{
"version": "1",
"default": "deny",
"hide": [
"delete-todo"
]
}delete-todo disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
