## Why neuron_semantic_search_contacts is rated Low

This tool retrieves and queries existing contact data based on semantic criteria. It does not create, modify, delete, execute code, or move money. The operation is purely informational with no side effects on the contact records themselves.

From the tool's own definition: "The tool performs semantic search to find contacts using natural language AI; returns ranked results with relevance scores and match reasons. Keywords indicating query/retrieval operation: 'search', 'finds', 'returns ranked results'."

## Use case

AI agents call neuron_semantic_search_contacts to retrieve information from Neuron 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 Neuron:

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