AI agents call multicall 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 |
|---|---|---|---|
calls | array | Yes | Array of calls to execute |
network | string | — | Network name. Defaults to mainnet. |
version | string | — | Multicall version (2 or 3). Defaults to 3. |
allowFailure | boolean | — | Whether to allow individual calls to fail. Defaults to true. |
multicallAddress | string | — | Optional Multicall contract address override |
Parameters from the server's own tool schema.
The tool explicitly states it executes 'read-only functions', meaning it only retrieves data from the blockchain without any side effects. Despite the word 'Execute' in the description, the 'read-only' qualifier makes this a Read operation. The batch nature doesn't increase severity since no writes occur.
From the tool's definition Execute multiple read-only functions in a single batch call

Attacks that exploit this kind of access
Execute multiple read-only functions in a single batch call. It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
multicall accepts 5 parameters: calls, network, version, allowFailure, multicallAddress. Required: calls. 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 multicall: 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.
multicall 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 multicall 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 multicall. 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.
multicall 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.
