Integration details

Description

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. LEGO® is a trademark of the LEGO Group of companies, which does not sponsor, authorise, or endorse Brick Budget. Brick Budget is also independent of BrickLink and Rebrickable.

Tools

28 tools agents can invoke

Read a page of set inventory with quantities multiplied by the requested number of sets. Does not save a budget. Fetch all pages before treating it as a complete breakdown.
break_down_set
Discover currencies, providers, colors, categories, availabilities, themes and years. Omit sections for all options or request selected sections. currencyId filters currencies, providers and retailers. Use currency Id, provider id, color Id and category strings in later calls. Check provider country and set/part capabilities; sharing a currency does not imply delivery coverage. Currency code may be unknown. Prices are not converted; BrickLink values are benchmarks.
get_catalog_options
Compare recorded prices across selected providers in one currency. Returns flat prices plus comparable groups, eligible retailer choices, differences, exclusions and missing coverage. Benchmarks, conditions and availability remain distinct; shipping and seller optimization are excluded.
compare_prices
Compare two to five sets, including metadata and shared/unique inventory quantities. Optional language selects official set-name presentation and defaults to English. Optional prices require currencyId and providerIds together. Missing sets and incomplete inventories are explicit; partial inventory is never a complete comparison.
compare_sets
Prepare up to 500 resolved set/part lines for review on the BrickBudget website. Returns JSON file content and a handoff URL, not a hosted file. The user uploads or pastes it and explicitly chooses merge or replace. Uses website pricing settings; no server budget is saved.
prepare_budget_handoff
Generate a supplied budget of at most 500 total lines as BrickLink XML or a text/HTML buy list using shared website identifiers and links. Returns file content; no file is hosted. Quotes exclude shipping and seller optimization.
export_budget
Assign each supplied line to the cheapest priced eligible selected provider in one currency. BrickLink benchmarks remain labeled estimates; unavailable retailer offers are excluded. This does not optimize shipping or seller baskets.
select_cheaper_prices
Find a bounded page of variants using the same design ID or part number grouping as the website.
get_part_variants
Find a bounded page of related same-name parts, excluding the source part.
get_related_parts
Check whether complete sets can reduce the estimated cost of supplied parts. Return matching and remaining parts, price coverage, and estimated spend reduction. Extra parts are not cash savings. Run only when requested or accepted as the next planning step.
find_set_savings
Read explanations of pricing limits, privacy, imports, set savings or the explicit Cart Helper handoff.
get_help
Read cached price records for up to 100 part IDs and six providers in one currency, without joining metadata. BrickLink values are benchmarks, not purchasable seller quotes. Missing prices remain null.
get_part_prices
Read cached price records for up to 100 set IDs and six providers in one currency, without joining metadata. BrickLink minimum values mean from; average values mean average. Source dates can be unknown.
get_set_prices
Read metadata for up to 100 mixed set and part references in one call, preserving input order and reporting missing IDs. Optional language applies only to set names and defaults to English. Prices are separate.
get_items
Read one part by internal catalog ID, including its design, color and website link. Returns null when absent. Fetch prices separately.
get_part
Read one set by internal catalog ID, including its canonical website link. Optional language requests an official name (default English); NameLanguage, NameFallback and NameOfficial identify the actual source. Returns null when absent. Fetch inventory and prices separately.
get_set
Pick one random part from the matching catalog: optional query, categories, colors and excluded IDs. Useful for building challenges and games. Returns null when no part matches; no prices.
get_random_parts
Pick one random set from the matching catalog: optional query, themes, years, size bounds, excluded IDs and official name language (default English). Useful for inspiration and games. Returns null when no set matches; no prices.
get_random_sets
Read statistics with explicit field scopes: set values use the selected provider, part presence covers the catalog, and legacy part ranges mix sources in the selected currency. Comparable price groups keep source, condition and availability separate. No historical lows.
get_item_stats
Resolve public purchase links for item IDs and providers in one currency. Links may be affiliate links. Returning a link does not open it or buy anything.
get_purchase_links
Read a bounded page of a set inventory as part IDs, quantities and inventory types. Follow pages and fetch part metadata or prices separately.
get_set_inventory
Parse supplied CSV, BrickLink XML, BSX or PBG text and resolve parts using website matching rules. At most 500 parsed lines and 3 MiB UTF-8 content, subject to the 4 MiB total JSON request bound. Content is processed transiently, not saved or shared-cache stored. Each row reports exact, fallback, ambiguous or unmatched resolution. Ambiguous rows are not auto-added. Review fallback matches and use prepare_budget_handoff to continue on the website.
import_parts_list
Prepare a LEGO Cart Helper payload of at most 500 total lines from resolved provider links and explicit website handoff instructions. The user must open the handoff page, validate the payload, and confirm sending it to their installed extension. This tool cannot control a browser, fill a cart or check out.
prepare_cart_helper
Estimate a supplied budget of at most 500 total lines using each line selectedProviderId, or the first provider when null. Return known subtotal and missing quantities, never imply an incomplete subtotal is a complete price. For parts, consider a separate find_set_savings call.
quote_budget
Search parts by query, category or color. Optional price bounds and availability require providerId and currencyId; country checks the provider country. Results include separate prices when a provider is selected. IDs identify catalog parts, not retailer element numbers.
search_parts
Search and paginate item prices for one provider and currency, sorted by recorded price. For Set results, optional language selects official name presentation (default English); it is invalid for Part results. Discover providers per currency and availability filters with get_catalog_options. Availability filters use the same normalized values as returned prices: available, unavailable, preorder, backorder or unknown. Unknown does not mean out of stock. Returns item metadata alongside prices. Metadata filters, price bounds and provider-country checks compose before pagination. This is not price-history search.
search_prices
Search sets by query, theme, year, size, group or all required part IDs. Optional language selects an official set-name language (en, pt-PT, es, fr, de, it, da); omitted means English. Search falls back to English only when the requested language has zero total matches. Results report total, searchLanguage and searchFallback. Optional price bounds and availability require providerId and currencyId; country checks that provider country, not delivery coverage. Price filters apply before pagination. Results include separate prices when a provider is selected and matching part quantities when parts are requested.
search_sets
Compute and return a revised copy of a supplied parts budget of at most 500 total lines. Supports add, remove, quantity, provider, clear, set replacement and undo operations on the returned list only. Never saves, clears or changes a stored budget, browser-local budget, cart or order. Retains UUIDs and replacement history in the returned data for later undo.

How do I improve Brick Budget's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
