Validate workout interval structure without creating a workout.
AI agents call tp_validate_structure to retrieve information from TrainingPeaks-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs validation—a query/check operation that retrieves or analyzes data to confirm structural correctness. No data is created, modified, deleted, or executed. The operation is read-only and side-effect free, making it a Read category tool with low severity since it cannot affect system state or user data.
From the tool's definition Tool name is 'tp_validate_structure' and description states it 'Validate[s] workout interval structure without creating a workout.' The phrase 'without creating' explicitly indicates no data modification occurs.
Attacks that exploit this kind of access
Validate workout interval structure without creating a workout. It is categorised as a Read tool in the TrainingPeaks-MCP MCP Server, which means it retrieves data without modifying state.
Register the TrainingPeaks- MCP server in PolicyLayer and add a rule for tp_validate_structure: 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_validate_structure is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tp_validate_structure 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_validate_structure. 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_validate_structure 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.
