Parameters from the server's own tool schema.
This tool retrieves balance information from the TRON blockchain. It performs a read-only query without creating, modifying, deleting, or executing any code. Even in the context of a blockchain server with financial operations available (transfers, approvals, proposals), this specific tool has no capacity to move funds or alter state.
From the tool's definition Tool name is 'get_token_balance' and description states 'Get the TRC20 token balance for an address' — a pure query operation with no side effects.

get_token_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_token_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.
