Lego Oracle

Gives your AI assistant direct access to Rebrickable's complete LEGO catalog: 26k sets, 62k parts, 17k minifigs, all embedded at build time so there's no runtime API needed. You get ten tools covering search, comparison, and lookup across sets, parts, and minifigures. Search for sets by theme or year, find which sets contain a specific brick in a specific color, compare multiple sets side by side to see shared parts, or look up minifig appearances. The browse_themes tool lets you navigate LEGO's theme hierarchy, and find_mocs surfaces community alternate builds. Useful when you're cataloging a collection, hunting down replacement parts, or just answering "which sets have that piece" without hallucinations.
