Steps to reproduce

1. Connect Cursor with Xcode MCP
   1.1 Toggle the "Allow agents to use Xcode tools" in the Intelligence tab of Xcode settings

1.2 Connect Cursor with Xcode MCP by adding this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "xcode-tools": {
      "command": "xcrun",
      "args": ["mcpbridge"]
    }
  }
}

2. Connect T3 Code with Cursor
3. Open Xcode
4. Start a thread with a Cursor model selected

Expected behavior

Xcode should show a permissions alert like this (when using original Cursor, it's shown twice) and user has to click Allow:

Actual behavior

When doing it via T3 Code, this is shown indefinitely. Every single time I click allow, there's a new alert with a different PID value.
