focus_ide · Claude Pascal MCP Server MCP: Risk & Policy

WHAT IT DOES

What focus_ide does on Claude Pascal MCP Server

AI agents invoke focus_ide to trigger actions in Claude Pascal MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why focus_ide needs a policy

Based on the server context (GUI automation, IDE observation), 'focus_ide' likely brings the IDE window into focus — an external UI operation. This is an Execute-level action (triggering external GUI interaction). Confidence is low due to empty description.

From the tool's definition Tool name 'focus_ide' on a server that enables IDE observation and GUI automation; description is empty.

Documented attack patterns abuse exactly the kind of access focus_ide gives an agent:

POLICY

How to control focus_ide

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

policy.json

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

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