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

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

## Why calculate is rated Low

This tool performs stateless mathematical operations. It retrieves no data, modifies nothing, executes no external commands or code, and has no destructive or financial implications. It is functionally equivalent to a calculator, making it a Read category tool with minimal security risk.

From the tool's own definition: "Tool description states 'Perform basic arithmetic calculations' which is a pure computation with no side effects, data retrieval, or external operations."

## Use case

AI agents call calculate to retrieve information from Nitrostack 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 Nitrostack:

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