Clear energy estimation cache
AI agents call clear_energy_cache to permanently remove resources in Tron — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing a cache is an irreversible operation that destroys stored data (cached energy estimations). However, the blast radius is low because cache data is derived/transient and can be regenerated; no financial assets or permanent data are affected. Categorized as Destructive over Write because the operation cannot be undone (cleared cache entries are gone).
From the tool's definition 'Clear energy estimation cache' - the word 'clear' implies irreversible deletion of cached data
Attacks that exploit this kind of access
Clear energy estimation cache. It is categorised as a Destructive tool in the Tron MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Tron MCP server in PolicyLayer and add a rule for clear_energy_cache: 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 Tron. Nothing to install.
clear_energy_cache 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 clear_energy_cache 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 clear_energy_cache. 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.
clear_energy_cache is provided by the Tron MCP server (netts-official/tron_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
