TinkerMCP

Experimental Model Context Protocol server for Tinkercad 3D Design.

The goal: let an AI operate Tinkercad's 3D editor through a small semantic toolset instead of treating the browser UI as an API.

Status: very early prototype / editor-discovery phase.

Architecture

AI / MCP client → TinkerMCP → remote browser automation → Tinkercad 3D

Tinkercad does not expose a public 3D-design API suitable for this use case, so TinkerMCP automates a real authenticated browser session. The semantic MCP API is intentionally separated from selectors and UI details.

Planned tools

  • create primitives (box, cylinder, etc.)

  • position, resize, rotate

  • solid / hole

  • duplicate / delete

  • align

  • group / ungroup

  • workplane

  • inspect selection / scene

  • export STL

Milestone 0 — bootstrap

The first milestone deliberately does not guess Tinkercad selectors. It provides:

  • MCP server foundation

  • persistent browser profile

  • tinkercad_open

  • tinkercad_inspect_editor

  • diagnostic capture tools for DOM/input/network observation

Render deployment

The hosted version will expose MCP over HTTP and is designed to deploy from GitHub automatically. Keep the Render service on the Free ($0/month) instance while prototyping.

The repository remains the single source of truth: changes go to main, Render auto-deploys, and no manual code copy/paste should be necessary.

Design principle

The model should see stable operations such as create_box({width, depth, height}). DOM selectors, drag mechanics, keyboard shortcuts and Tinkercad-specific implementation details stay behind the adapter.

Inspiration

  • sethski/tinkercad-mcp-server — community MCP for Tinkercad Circuits using a persistent browser.

  • Model Context Protocol.

  • Playwright / remote browser automation.
