AppWrangler

Free, open-source menu bar app that keeps the app you're using fast: background apps go to efficiency cores, idle apps are frozen when memory runs low, plus per-app CPU and memory limits, a widget, and an MCP server for Claude. Apple Silicon. A rewrite of AppPolice.

Known working client config (can write into mcp.json):
{
  "mcpServers": {
    "appwrangler": {
      "command": "npx",
      "args": [
        "https://github.com/IntarsO/AppWrangler/releases/download/v1.7.1/AppWrangler-mcp-1.7.1.mcpb"

    }

Please: 1) check README for deps and env vars; 2) write config for my client; 3) if secrets are missing, tell me what to fill — do not invent values.
