OrcaSlicer MCP is OrcaSlicer 2.3.2 with a built-in local control API, so AI assistants (Claude Desktop, Claude Code, or any MCP client) can drive the slicer through the orcaslicer-mcp server — load models, tune settings, slice, and analyze results, live in the GUI.

Get started: install this build, then follow the quickstart (5 minutes: enable the API in Preferences, copy the token, add the MCP server to your client config).

Install notes (unsigned builds)

These are community builds — ad-hoc signed but not notarized/signed with a paid developer certificate.

  • macOS: the app runs on Apple Silicon and Intel, but Gatekeeper blocks the first launch ("Apple could not verify… is free of malware"). To open it, either:

    • Try to open it once (it'll be blocked), then go to System Settings → Privacy & Security, scroll to the Security section, click Open Anyway, and confirm; or
    • Run in Terminal: xattr -dr com.apple.quarantine /Applications/OrcaSlicer.app

    (The old right-click → Open shortcut no longer works on macOS 15 Sequoia and later.)

  • Windows: SmartScreen may warn — click More info → Run anyway.

Security defaults

The control API is off until you enable it, listens on 127.0.0.1 only by default (LAN access is a separate explicit toggle), and every request requires the API token OrcaSlicer generates for you.

What's changed vs stock OrcaSlicer 2.3.2

Only the Remote API layer (HTTP + WebSocket on port 13130) and its Preferences page — no slicing-engine changes. Full diff: main...remote-api.

Note: OrcaSlicer's built-in "new version available" prompt points at stock OrcaSlicer — installing that way replaces this build and removes the control API. Get new MCP-enabled builds from this releases page instead.
