## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "getBalanceOf",
    "arguments": {}
  }
}
```

## Why getBalanceOf is rated Low

This tool performs a read-only query of token balances on the Ethereum blockchain. It has no side effects, does not modify state, and does not execute code or transfer funds. The impact of misuse is minimal—an attacker could only discover balance information already visible on public blockchains.

From the tool's own definition: "Tool name 'getBalanceOf' and description 'Gets the ERC20 token balance of an address' indicate a query operation that retrieves blockchain state without modification or execution of arbitrary code."

## Use case

AI agents call getBalanceOf to retrieve information from Agentek Eth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Agentek Eth:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "getBalanceOf": {}
  }
}
```
