Environment

Name	Required	Notes
ORCA_API_TOKEN	Yes	Remote API token from the OrcaSlicer MCP build (Preferences -> Remote API) Secret.
ORCA_API_URL	No	OrcaSlicer Remote API address; defaults to http://127.0.0.1:13130
ORCA_MCP_ALLOW_KEYS	No	Optional comma-separated config keys the MCP may change even though they run code or drive the printer directly (post_process, *_gcode, print host settings). Wildcards allowed. Blank by default.
ORCA_PRINTER_URL	No	Optional printer address; by default the address in OrcaSlicer's active printer profile is used. A user name and password can be part of it (http://user:password@192.0.2.10); percent-encode special characters in them (@ as %40). A password in it is stored as an ordinary setting, so prefer ORCA_PRINTER_API_KEY where the printer accepts a key.
ORCA_PRINTER_API_KEY	No	Optional API key for printers that need one (OctoPrint, or Moonraker with authorization). Secret.
ORCA_PRINTER_ID	No	Optional printer name for the outcome store; defaults to the host name of ORCA_PRINTER_URL when that is set, otherwise the printer profile's name, otherwise unknown.
