  -e SHELL_USE_SESSIONS=dev \
  -- docker run -i --rm \
  -v /tmp/tmux-$(id -u)/default:/tmux/tmux.sock \
  -e SHELL_USE_SESSIONS \

{
  "mcpServers": {
    "shell-use": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-v", "/tmp/tmux-1000/default:/tmux/tmux.sock",
