## Why search_modules_people is rated Low

The tool performs a search/query operation to retrieve information about people in Slack, which is a read-only action with no side effects. However, severity is elevated to medium because searching for people data could expose personally identifiable information (PII) or organizational structure details if misused by an agent, depending on access controls and what data is returned.

From the tool's own definition: "Tool name 'search_modules_people' indicates a search operation querying people data. Server description states it provides 'search' capabilities for accessing Slack data. No modifying, destructive, or financial operations are implied."

## Use case

AI agents call search_modules_people to retrieve information from Slack 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 Slack:

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