## Why search_slack_messages is rated Low

This tool queries and retrieves data (Slack messages) without modifying, deleting, or executing actions. It is purely informational. Severity is medium rather than low because searching across all channels in a workspace could expose sensitive messages (PII, confidential discussions, private conversations) depending on workspace permissions and what the AI agent searches for, creating potential information…

From the tool's own definition: "Tool description states it 'Search[es] messages across all channels in the Slack workspace' and 'Requires user authorization (search:read scope)'. The word 'search' and 'read' scope confirm this is a retrieval operation with no side effects."

## Use case

AI agents call search_slack_messages to retrieve information from Freshdesk 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 Freshdesk:

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