Free, open skills that teach your AI agent to design real, manufacturable things in Axle Keys.
Axle Keys is a parametric CAD platform. You describe a physical object; your agent writes the model, Axle builds the geometry on its server, checks it, and hands back something with named parameters you can actually adjust. These skills are the choreography — install one, and your agent knows the whole workflow.
| Skill | Tier | What it does |
|---|---|---|
brief-to-model |
Free | Turn a plain-English description into a real parametric 3D CAD model — built, dimension-verified, and shown back as a picture you can spin. |
Everything here runs against the hosted Axle Keys MCP endpoint:

Claude Code
claude mcp add --transport http axle-keys https://api.axlekeys.com/mcpclaude.ai / ChatGPT — add it as a custom connector by URL in your connector settings.
Clone this repo, then copy the skill you want into your project's skills directory:
git clone https://github.com/AxleKeys/skills.git axle-skills
cp -r axle-skills/skills/brief-to-model .claude/skills/The clone is named axle-skills on purpose — this repo's folder is also called skills,
so cloning it bare leaves you with skills/skills/… and a copy command that misses by one
level.
On claude.ai, add the skill's SKILL.md to your project's knowledge instead.
Then just describe what you want to make. The skill triggers on its own.
Axle Keys is currently invitation-only. Signing up needs a Keyholder code — request one at axlekeys.com.
Already have a code? Connect your agent and you're a minute away from your first model.
Issues and skill ideas are very welcome — open an issue.
Skill authorship stays in-house for now. A skill is a set of instructions that your agent obeys, so accepting one from a stranger is closer to accepting an advertisement than a patch, and we'd rather get the review process right before opening that door.
