PARALLELSANDBOX_API_KEY	—	yes	Optional existing psbx_ API key; without it the adapter opens OAuth sign-in
PSBX_TOOL_TIMEOUT_SEC	—	—	Configured MCP host absolute tool timeout in seconds (default 60 gives a safe 25-second review wait; set both the host timeout and this value to 1920 for a 30-minute wait). Requires adapter restart.
