Brick Budget helps builders plan LEGO® parts lists and estimate build budgets. Search sets and parts, inspect inventories, and compare recorded prices from supported providers in one stored currency. Smart Suggestions checks whether buying complete sets could reduce the estimated cost of the parts you need.
Import supported parts lists, identify matching exceptions and missing prices, and export a buy list. Prepare an explicit handoff to review a list on the Brick Budget website, or a Cart Helper payload for the optional browser extension. You decide whether to open a page or send a list to the extension. The plugin cannot place orders, process payments, complete checkout, or automatically read or change your browser-local budget. No Brick Budget account or API key is required.
Prices are recorded observations, not guaranteed checkout totals. BrickLink values are benchmarks, not individual seller offers. Comparisons exclude shipping and seller-basket optimization. There is no currency conversion or historical-low-price guarantee. Some purchase links are affiliate links; a purchase through them may earn the operator a commission.
Only the tool arguments selected for your request are sent to Brick Budget, including search terms and any supplied parts lists. Inputs are processed transiently; derived public catalogue results may be cached for up to 15 minutes. When configured, optional MCP usage analytics record tool names, outcomes, timings and bounded cache/database counters using a weekly IP-derived pseudonymous identifier. Raw IPs, search text, submitted lists, budgets, item identifiers and returned links are excluded from analytics events. Add ?analytics=off to the connection URL or send DNT: 1 on every request to opt out. Necessary hosting, operational and security processing still applies; the website cookie choice is separate. See the privacy policy for details.
