Why vscode_dismiss_notification needs a policy

This tool performs a UI interaction (clicking a close button) within VSCode to dismiss notifications. It's an action with side effects — it triggers a UI event that removes a notification from the interface. While not destructive to data, it is an execution of a UI action that could cause an AI agent to dismiss important alerts or warnings that a user or workflow depends on.

POLICY

How to control vscode_dismiss_notification

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

policy.json

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

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