AI agents call get_balance 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.
This tool performs a read-only operation on the TRON blockchain to fetch account balance information. It has no side effects, does not execute code or transactions, and does not modify state. The blast radius is minimal as misuse would only expose publicly available blockchain data.
From the tool's definition Tool name 'get_balance' and description 'Get TRX balance for an address' indicate a query operation that retrieves blockchain data without modification or execution of code.
Attacks that exploit this kind of access
Get TRX balance for an address. It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
Register the Tron MCP server in PolicyLayer and add a rule for get_balance: 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.
get_balance 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 get_balance 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 get_balance. 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.
get_balance 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.
