## Why wavexis_get_pref is rated Low

This tool retrieves configuration/preference data from the browser without any side effects. It matches the 'Read' category definition: queries data with no side effects. The severity is low because accessing browser preferences poses minimal risk; an agent could learn about browser settings but cannot modify state or trigger external operations.

From the tool's own definition: "Tool name is 'wavexis_get_pref' and description states 'Get a browser preference value by key' — explicitly a retrieval operation with no modification."

## Use case

AI agents call wavexis_get_pref to retrieve information from Wavexis 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 Wavexis:

```json
