BrickBudget MCP
Use BrickBudget in your AI assistant
Ask about LEGO set and part prices, compare providers, and find out whether buying a whole set could lower the cost of your parts list.

Price and privacy details
BrickBudget MCP is completely FREE to use.
Your AI assistant provider may charge separately for its service.
Prices come from BrickBudget’s curated database and include their recorded update date when available. BrickLink values are benchmarks, so the MCP shows them as “from” prices rather than a seller offer.
Comparisons cover recorded set and part prices only. They do not include shipping, seller optimisation, checkout fees, or a claim about the lowest price ever. Your website budget does not automatically sync with an MCP conversation.
BrickBudget does not need an account or key for this connection. If you send an import or parts-list file through your assistant, its contents reach BrickBudget’s servers for matching and are discarded after processing. Any information you share in a chat is also subject to your assistant provider’s privacy settings.
