OrcaSlicer MCP 2.3.2-mcp.2

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.

What's new in mcp.2

• The in-app "new version available" prompt is disabled. Because this build is based on OrcaSlicer 2.3.2, upstream's updater used to offer to "upgrade" you to stock OrcaSlicer — which removes the control API. That update check is now turned off entirely, so the fork can't accidentally replace itself. (New MCP-enabled builds still come from this releases page.)

SHA256SUMS.txt covers all assets.

Install notes (unsigned builds)

Ad-hoc signed but not notarized/certificate-signed:

• macOS: the app runs on Apple Silicon and Intel, but Gatekeeper blocks the first launch. To open it, either try to open it once (it'll be blocked) then go to System Settings → Privacy & Security → Open Anyway and confirm; or run xattr -dr com.apple.quarantine /Applications/OrcaSlicer.app. (The old right-click → Open shortcut no longer works on macOS 15+.)
• 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

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

OrcaSlicer MCP 2.3.2-mcp.1

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

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.
