Common questions
Is 3DOptix safe?
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 4 months ago, and the latest version (1.0.0) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?

3DOptix for AI coding agents
Design, simulate and analyse optical systems from your coding agent, using the 3DOptix cloud platform.
This repository is a plugin — it bundles the 3DOptix MCP server together with a skill that teaches the agent how to use it well. Install it once and your agent can build optical setups, place lenses and detectors, run GPU ray-trace simulations and advanced optical analysis.
Skills here follow the Agent Skills open standard, so they work in Claude Code, Codex, Cursor and other compliant clients.

Just the MCP server
If you only want the tools and not the workflow guidance, the server is listed in the MCP Registry as com.3doptix/optical-design, or add it directly:
claude mcp add --transport http 3doptix https://mcp.3doptix.comConnect your account
You need a 3DOptix account. New sign-ups at 3doptix.com get a fully functional trial; continued use needs a subscription.
Authentication is OAuth 2.0 with dynamic client registration. There is no API key to paste.
- Claude Code — run
/mcp, select 3doptix, sign in via the browser. - Codex — run
codex mcp login 3doptix.
Then confirm it worked by asking your agent to list your setups. Your agent can also walk you through this itself — the bundled 3doptix-setup skill activates on connection errors. Full troubleshooting: skills/3doptix-setup/SKILL.md.
What's included
| Skill | What it covers |
|---|---|
3doptix-workflow | Setup creation, component placement and alignment, light sources, detectors, catalog and custom optics, simulation, analysis, optimisation, Zemax import, CAD upload |
3doptix-setup | Connecting and verifying the MCP server; activates on auth errors |
The 3doptix MCP server provides tools for setups, parts, the optics and optomechanics catalogs, simulation, analysis and rendering. Tool reference: 3doptix.com.

Repository layout
.claude-plugin/ Claude Code plugin + marketplace manifests.codex-plugin/ Codex plugin manifest .agents/plugins/ Codex marketplace manifest .mcp.json The 3DOptix remote MCP server server.json MCP Registry entry skills/ Agent Skills — shared by every store assets/ Store icons (the spectral sphere from the 3DOptix mark) scripts/ validate.js, set-version.js — plain Node, no dependencies
Skill content lives in exactly one place. Each store gets a small manifest pointing at the same skills/ tree — nothing is duplicated per client.
There is no build step. Skills are Markdown and manifests are JSON, so what you see here is exactly what gets installed.
Contributing
Adding a skill
Create skills/ /SKILL.md with the required frontmatter:
---name: your-skill-name description: "When this skill should and should not trigger."
name must match the directory name — every store enforces this. Put anything lazily loaded in skills/ /references/ and point at it from SKILL.md. Skills are discovered by directory, so there is no manifest to register a new one in.
Only skills under skills/ ship. A skill still in development belongs in an inactive-skills/ directory instead — no store scans it there, so it can live in the repository without reaching users.
Checks
node scripts/validate.jsNo install step; it has no dependencies. It checks skill frontmatter against the Agent Skills spec, confirms all four manifests agree on a version, and refuses to pass if .mcp.json ever grows a credential. CI runs the same script on every push and pull request.
Before publishing a change, also confirm what a user will actually receive:
claude plugin details 3doptixReleasing
.claude-plugin/plugin.json holds the authoritative version. To cut a release:
node scripts/set-version.js 1.1.0 # writes all four manifestsnode scripts/validate.js git commit -am "release: 1.1.0" && git tag v1.1.0 git push && git push --tags
Never edit a manifest's `version` by hand — validate.js will fail, which is the point.
Directories that list this plugin track commits on main and pick up changes automatically, so a push is a release whether or not you tag it. Tag anyway; it is how users pin a known-good version.
