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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "getDecimals",
    "arguments": {}
  }
}
```

## Why getDecimals is rated Low

This is a straightforward read operation querying token metadata from the blockchain. It retrieves information (token decimals) without creating, modifying, deleting, or executing any transactions or code. The blast radius of misuse is minimal since the tool only exposes public blockchain data that is already accessible via standard RPC calls.

From the tool's own definition: "Tool description states it 'Gets the number of decimals of an ERC20 token' — a query operation that retrieves metadata about a token contract with no side effects or state changes."

## Use case

AI agents call getDecimals 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": {
    "getDecimals": {}
  }
}
```
