The colour science and rendering are the same ones the vendor's own site runs, so the preview is a faithful look at what the physical build would be rather than an approximation made for the agent. Treat it as the exploration step: the buildable outputs — instructions, parts list, placement matrices — come from the paid site.
A single-tool MCP server that converts a local image into a 3D-rendered brick mosaic. It runs the same colour-quantization and rendering pipeline as bmbrick.com, on your own machine through Node, and returns a watermarked PNG preview plus a link to unlock the full project. The tool was renamed from `generate_bmbrick_mosaic` to `generate_lego_mosaic`, and the package from `@bmbrick/agent-mosaic-skill` to `@bmbrick/photo-to-lego-mosaic-skill`; parameters and return shape are unchanged.
- A brick mosaic rendered from an absolute path to a local image — `generate_lego_mosaic`
- A stud grid you choose: `columns` and `rows` default to 48 and go up to 64
- Square or round tiles via `materialMode`, set to `square_1x1` or `round_1x1`
- 3D rendering with realistic studs, rather than a flat pixel grid
- Optional background removal for white or transparent backgrounds, via `removeBackground`
- Local processing — the image is read from your disk and the render happens on your machine
- A `SKILL.md` in the package, so agents that read skill files pick up the workflow without extra prompting
No account and no key. Run `npx -y @bmbrick/photo-to-lego-mosaic-skill` (published as `@bmbrick/photo-to-lego-mosaic-skill` 2.0.2) over stdio; the tool takes an absolute path, so the image has to be on the same machine. What comes back is a watermarked preview: the unwatermarked mosaic, the brick-by-brick PDF instructions, the parts list with ordering links and the placement matrices are bought at bmbrick.com. The npm wrapper and skill directory are MIT; the engine files in `dist/` are free to use and redistribute as-is but not to reverse-engineer or modify.
One command — npx -y @bmbrick/photo-to-lego-mosaic-skill
