## Why gdelt_tone_analysis is rated Low

This tool queries and analyzes existing data (news sentiment/tone) and returns computed metrics. It is a read-only retrieval operation with no side effects. The data is pre-existing and the tool merely performs sentiment analysis on it. The severity is low because misuse would only result in retrieving information, not causing harm to systems or data.

From the tool's own definition: "Tool description states it 'Analyse[s] the sentiment and tone of global news coverage' and 'Returns average tone scores... and timeline'. The verbs are analytical and retrieval-focused: analyse, returns."

## Use case

AI agents call gdelt_tone_analysis to retrieve information from UnClick 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 UnClick:

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