BMBrick Agent Mosaic Skill

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

@bmbrick/agent-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.

Visual Previews

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

Square Tiles (square_1x1)

Original Photo	48x48 Preview	64x64 Preview

Round Tiles (round_1x1)

Original Photo	48x48 Preview	64x64 Preview

Quick Start
