Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`SLICER_WORKSPACE` Optional	The only directory this server reads and writes. Defaults to ~/cad.
`SLICER_BIN` Optional	Path to the slicer binary. Auto-detected if unset. Creality Print's CLI does not work headless on macOS; prefer OrcaSlicer, Bambu Studio or ElegooSlicer there.
`SLICER_PROFILE_DIRS` Optional	Extra profile roots, os.pathsep separated. Added to the auto-detected roots rather than replacing them.
`SLICER_TIMEOUT` Optional	Seconds before a slice is killed. Defaults to 600.
