AI agents call delegate_resource 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 |
|---|---|---|---|
lock | boolean | — | Whether the delegation is locked (non-revocable within the lock period). Defaults to false. |
amount | number | Yes | Amount of resources to delegate in Sun (1 TRX = 1,000,000 Sun) |
network | string | — | Network name. Defaults to mainnet. |
resource | string | Yes | Resource type to delegate (BANDWIDTH or ENERGY) |
lockPeriod | number | — | Lock period in blocks when lock is true. Ignored if lock is false. Defaults to 0. |
receiverAddress | string | Yes | The address that will receive the delegated resources |
Parameters from the server's own tool schema.
Even though delegate_resource only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Delegate staked resources (BANDWIDTH or ENERGY) from the configured wallet to another address. It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
delegate_resource accepts 6 parameters: lock, amount, network, resource, lockPeriod, receiverAddress. Required: amount, resource, receiverAddress. 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 delegate_resource: 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.
delegate_resource 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 delegate_resource 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 delegate_resource. 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.
delegate_resource 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.
