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

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

## Why get_balance is rated Low

This tool performs a read-only blockchain query to fetch balance information. It has no side effects, cannot modify state, and poses minimal security risk even if misused by an AI agent—the worst case would be information disclosure of already-public on-chain data. It clearly falls under the 'Read' category (retrieves data; no side effects).

From the tool's own definition: "Tool name 'get_balance' and description 'Get the native token balance (Sei) for an address' indicate a pure query operation that retrieves account balance data without modification, deletion, or execution of code."

## Use case

AI agents call get_balance to retrieve information from SEI MCP Server V2 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 SEI MCP Server V2:

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