3DOptix — Claude Code MCP server: optical design and simulation
Hooks your coding agent up to the 3DOptix cloud platform for building optical setups, GPU ray tracing, and Zemax or CAD import.
claude mcp add --transport http optical-design https://mcp.3doptix.comWhat 3DOptix does
3DOptix exposes the 3DOptix cloud platform to your agent over MCP. It can lay out an optical setup, position lenses and detectors, define light sources, run a GPU ray-trace simulation, and pull up the analysis afterwards. Zemax files and CAD models come in through the same server.
Two skills ship alongside the tools. 3doptix-workflow covers the actual process: creating a setup, placing and aligning components, picking optics from the catalog or defining custom ones, then optimising. 3doptix-setup fires when the connection breaks and walks through verifying the server.
You need a 3DOptix account. Signing up gives a fully functional trial; keeping it going past that requires a subscription. Login is OAuth 2.0 with dynamic client registration, so there is no key to copy anywhere. In Claude Code, run /mcp, pick 3doptix, and finish signing in through the browser. Nothing gets compiled on install: skills are Markdown and the manifests are JSON, so the installed tree matches the repository exactly.
What it helps with
- build a lens-and-detector layout from inside the chat
- run a ray trace and inspect the spot diagram
- bring a Zemax project over and locate the worst aberrations
- pick catalog optics that fit a given beam
- upload a CAD model and fit it into the setup
Example prompts for the agent
- Import my Zemax file into 3DOptix and tell me where the aberrations are worst.
- Check the 3doptix connection and list my setups.
