Agent Mosaic Skill MCP server

BMBrick Photo-to-LEGO-Mosaic Skill

Convert any local photo into a LEGO-style brick mosaic preview — directly from your AI agent.

@bmbrick/photo-to-lego-mosaic-skill is an MCP server that lets Claude, Cursor, Windsurf, and other AI agents transform local images into high-fidelity 3D brick mosaics using the same canonical engine as bmbrick.com.

Renamed from @bmbrick/agent-mosaic-skill (the old name still works but is deprecated — please migrate to the new name for future updates).

Visual Previews

Generated with the generatelegomosaic tool (3D render mode):

Square Tiles (square1x1)**

Round Tiles (round1x1)**
