LEGO Oracle

LEGO sets, parts, minifigs, and inventories. An MCP server.

Ask your AI assistant about LEGO sets, find specific bricks, look up minifigures, browse themes, and compare sets. All backed by Rebrickable's catalog (26k sets, 62k parts, 17k minifigs), not hallucinations.

10 tools. Zero config. Works with every MCP-compatible IDE.
