# How to let an AI agent model a part you can still edit with solidcraft

Repo: [tangency-labs/solidcraft](https://github.com/tangency-labs/solidcraft) | Difficulty: Intermediate | Time: 45 minutes | Basis: Seen in the wild

Steer an agent through the built-in MCP server and get a real parametric model, not a mesh you can't fix.

**Who it is for:** Maker who tried text-to-3D tools and got meshes they could not adjust

**The problem:** Text-to-3D tools give you a frozen mesh, so a wrong hole size or wall thickness means starting over.

**The outcome:** You get a feature-timeline model where every dimension is still editable after the agent is done.

## Steps

1. Download the app for your OS from the README, or use the browser version.
2. Register the MCP server with Claude Code: claude mcp add solidcraft -- solidcraft-cli mcp
3. Ask the agent to model your part and describe the key dimensions.
4. Open the result and change a dimension in Parameters to confirm it rebuilds.

## Prompt to paste into your agent

```text
Using the solidcraft MCP server, model <part description with dimensions> as a parametric design. Expose the key sizes as parameters and tell me which ones to change. Verify the model rebuilds when one parameter changes.
```

## Caveat

The README calls SolidCraft early but usable for simple parts, so complex assemblies from an agent may need manual cleanup.
