## Why detect_language is rated Low

The tool performs language detection analysis on provided text and returns results. There are no side effects, data modifications, code execution, deletions, or financial implications. It is purely informational/analytical, fitting the Read category for retrieval and query operations.

From the tool's own definition: "Tool description states it 'Detect[s] the language of the provided text' and 'Returns the detected language with confidence score and alternative language candidates.' This is a query operation that analyzes input without modifying or creating data."

## Use case

AI agents call detect_language to retrieve information from AWS 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 AWS:

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