WHAT IT DOES

What preview_voice does on Freshdesk

AI agents call preview_voice 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.

RISK

Why preview_voice is rated Low

The tool generates a temporary audio preview for evaluation purposes and explicitly states it does not create or persist anything. This is a read/query-style operation with no side effects, making it a Read category with low severity.

From the tool's definition 'Generate a short audio preview' and 'without creating it' — explicitly states no persistent creation occurs

RECOMMENDED RULE

The rule that runs preview_voice safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Freshdesk, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For preview_voice, this is the rule to start with:

preview_voice Allowed

preview_voice is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "preview_voice": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Freshdesk, apply this rule, and every preview_voice call is checked against it from then on.
