Spree Commerce: open-source B2B and marketplace ecommerce
Open-source B2B and marketplace ecommerce; new stores include an MCP server for AI agents.
Description from the maker (original English)
Agent car inventory index. Synthetic demo data, not real inventory, not an offer.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
search_inventorySearch the SYNTHETIC demo inventory (about 860 fictional vehicles at 20 fictional dealers in TX, CA, FL, GA, AZ, IL, NY and OH). Results are not real vehicles for sale; say so when you show them. Each result has listing_id (dealer_key:VIN), vehicle basics, headline_price (before
list_searchable_fieldsEvery filterable ontology field (vehicle, listing, store, dealer, price, fee, incentive, media, payment) with its type, range or allowed values, shortcut names, the operators (eq, any_of, contains, range, bool, exists, negate) and example filters for search_inventory. The full co
get_payment_estimateUse this to answer 'what would my monthly payment be' for ONE listing. It runs the same itemized out-the-door calculation as estimate_out_the_door (always treated as financed) and turns it into a DEMO monthly finance payment: out-the-door total minus down payment and trade equity
compare_payment_scenariosUse this to compare several financing what-ifs for ONE listing side by side in one call (for example cash down, term, credit tier or APR, trade-in, incentives). Each scenario reruns the itemized out-the-door estimate and returns estimated_out_the_door, amount_financed_estimate, a
register_agentOptional and free. Registers your agent and returns an agent key (shown once) that gives it a durable, anonymous id in Moonshot Lab's bot analytics. Send it as the X-MoonshotLab-Agent-Key header, or add ?agent_key= to the MCP URL. Nothing else changes: anonymous use keeps working
save_searchDEMO. Save a car search and get alerted when new cars match. Returns a search_id (keep it; it is the only way to read or cancel the search) and an expiry (default 30 days, renewable). Check for new cars with get_new_matches, or give a callback_url. Shopper email alerts are option
get_new_matchesDEMO. New cars that started matching a saved search after it was saved (or after `since`).
cancel_searchDEMO. Cancel a saved search. Any shopper email stored for it is deleted.
prepare_dealer_handoffUse this when the shopper has picked a car and a deal structure and wants to take it to the dealer. Builds a structured dealer handoff package for ONE configured deal: vehicle and VIN, the full itemized out-the-door estimate (with excluded items such as optional add-ons), the cho
get_listingFull synthetic listing record with per-value provenance (method 'synthetic'). listing_id is dealer_key:VIN (as returned by search_inventory) or the urn. The vehicle-to-store link is in listing.selling_location (link_status, selling_location_id, candidates, flags such as group_sit
get_price_breakdownUse this to see what the dealer LISTS for ONE listing, as published: headline price, MSRP (new cars), price_components, dealer fees (doc fee and others) and fee bundles (parts marked part_of_bundle, not double counted), flags such as whether the advertised price already includes
estimate_out_the_doorUse this for the buyer's TOTAL price of ONE listing: an itemized out-the-door DEMO ESTIMATE for the buyer's state, county and city, built with real public tax and fee rules for the 8 covered states. Lines include the price, dealer fees, eligible incentives, state and local sales
get_dealerFictional dealer profile: registry entity, stores (selling locations) with fictional addresses and 555 phone numbers, group, state rules and a page of inventory. Not a real business; do not tell anyone to call or visit.
list_dealersAll 20 fictional demo dealers with group and store counts (each dealer lists its stores with group_id, region_id and store_id), the dealer hierarchy (Group, then Region, then Store), the 4 fictional dealer groups and a coverage summary: which metros have demo stores, with dealer,
get_mediaMedia block for a listing: self-generated SVG placeholder images labeled DEMO (photo, video poster, spin), with rights notes. They are not photos of a real car. No video or 360 viewer exists in the demo.
get_trade_in_scenariosReady-made demo trade-in scenarios (one per state) with trade_value and payoff to pass to estimate_out_the_door or get_payment_estimate.
get_ontologySchema links, schema version, covered states, condition values, search sorts and the value-wrapper format ({v, m, c, src}). For the list of filterable fields and allowed values, use list_searchable_fields.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0-demo) reached the registry 22 days ago.
