AI agents call estimate_energy to retrieve information from Tron without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
abi | array | Yes | Contract ABI (required for encoding) |
args | array | — | Function arguments |
address | string | Yes | Contract address |
network | string | — | Network name. Defaults to mainnet. |
functionName | string | Yes | Function name to call |
ownerAddress | string | — | Caller address for simulation. Defaults to configured wallet. |
Parameters from the server's own tool schema.
This tool performs a dry-run or simulation to predict resource consumption without creating side effects. No funds move, no state changes occur, and no irreversible actions are taken. It is purely informational, similar to a gas estimation tool in Ethereum.
From the tool's definition The tool description explicitly states it "Estimate[s] energy consumption for a smart contract call (simulation)".
Attacks that exploit this kind of access
Estimate energy consumption for a smart contract call (simulation). It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
estimate_energy accepts 6 parameters: abi, args, address, network, functionName, ownerAddress. Required: abi, address, functionName. The full parameter table on this page comes from the server's own tool schema.
Register the Tron MCP server in PolicyLayer and add a rule for estimate_energy: 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.
estimate_energy 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 estimate_energy 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 estimate_energy. 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.
estimate_energy is provided by the Tron MCP server (@bankofai/mcp-server-tron). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
