Why disconnect_from_voice needs a policy

This tool forcibly removes a user from a voice channel, which is an active operation with immediate real-world effects on a Discord member's session. It's not purely destructive (data isn't deleted), but it executes an administrative action against a user. The blast radius is high because it could be misused to disrupt legitimate users or harass members at scale in a server with many members.

From the tool's definition Disconnect a member from their current voice channel

POLICY

How to control disconnect_from_voice

PolicyLayer is an MCP gateway — it sits between your AI agents and Discord, and nothing reaches the server without passing your rules. This is the rule we recommend for disconnect_from_voice:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "disconnect_from_voice": {
      "limits": [
        {
          "counter": "disconnect_from_voice_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

disconnect_from_voice stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Discord — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
