Delete an event.
AI agents call tp_delete_event to permanently remove resources in TrainingPeaks-MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs an irreversible deletion of an event object. Once deleted, the event and associated data cannot be recovered without external backup/undo mechanisms. This meets the definition of Destructive category. Severity is high because deletion of training events could disrupt an athlete's training plan, calendar, and historical records.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete an event.' This is an irreversible deletion operation.
Attacks that exploit this kind of access
Delete an event. It is categorised as a Destructive tool in the TrainingPeaks-MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TrainingPeaks- MCP server in PolicyLayer and add a rule for tp_delete_event: 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 TrainingPeaks-MCP. Nothing to install.
tp_delete_event 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 tp_delete_event 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 tp_delete_event. 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.
tp_delete_event is provided by the TrainingPeaks- MCP server (jamsusmaximus/trainingpeaks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
