Parameters from the server's own tool schema.
This tool performs a simple read operation to retrieve blockchain account balance information. It has no side effects, does not modify any data, and does not execute code or transactions. The blast radius of misuse is minimal—an attacker could enumerate balances but cannot move funds or cause irreversible changes. Classification as Read is appropriate.
From the tool's definition Tool name is 'get_balance' and description states 'Get the TRX balance for an address'. This is a query operation that retrieves account balance data without modifying or executing any state-changing operations.

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 (@bankofai/mcp-server-tron). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
