```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why who.health.data is rated Low

Tool retrieves public health statistics without modifying data or triggering external operations.

From the tool's own definition: "Retrieve WHO health data, filtered by country and year range"

## Use case

AI agents call who.health.data to retrieve information from Apibase 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 Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "who.health.data": {}
  }
}
```
