Windows · FreeRequires Rhino 8 + Claude Desktop
Getting started
1
Install Claude Desktop
Download and install Claude Desktop from claude.ai/download. Create a free Anthropic account or log in if you already have one.
One time2
Update Rhino to the latest version
Make sure you're on the most current Rhino 8 release. GH Agent relies on up-to-date SDK components — older builds may cause compatibility warnings or silent failures. In Rhino, go to Help → Check for Updates.
Rhino 8.30 or later is strongly recommended.
3
Run the installer
Download and run GHAgent_Setup.exe. The wizard installs everything — no admin rights, no terminal. It checks for Python 3 and Rhino 8, installs dependencies, and configures Claude Desktop automatically.
~2 minutes4
Restart Rhino
Close and reopen Rhino 8 so Grasshopper picks up the new plugin from your Libraries folder.
Required5
Drop the component on your canvas

Connect the Claude Project (Forthcoming)
We will develop skills and share them as a Claude Project. In the future, click the link below to import the GH Agent skills into Claude Desktop. This gives Claude knowledge of Grasshopper components, workflows, and how to assist you.
→ Open Claude Project (Forthcoming)7
Start chatting
Open Claude Desktop and describe what you're trying to build. Claude can read your canvas, diagnose errors, add components, and write scripts — all from a conversation.
