THE RISK

Why discord_screenshot needs a policy

This tool executes a system-level operation (capturing the entire desktop screen) and then transmits the result to an external service (Discord). It involves both running an OS-level action and exfiltrating potentially sensitive information visible on screen. The blast radius is high because it can expose confidential data, credentials, code, or personal information visible on the desktop at the time of capture.

From the tool's definition 'Take a screenshot of the entire desktop' — captures the full desktop state and sends it externally to Discord

POLICY

How to control discord_screenshot

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

policy.json

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

discord_screenshot 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 Mcp Agent — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
