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

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

## Why economy_inflation is rated Low

This tool queries and retrieves publicly available economic data from the World Bank API. It is a read-only operation that fetches inflation statistics without creating, modifying, deleting, or executing any side effects. The data returned is informational and poses no security risk from misuse.

From the tool's own definition: "Tool description states 'Get the latest consumer price inflation rate (CPI)' — a retrieval operation with no modification, deletion, or execution of code/commands."

## Use case

AI agents call economy_inflation to retrieve information from Nodebench 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 Nodebench:

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