OpenDealer MCP Server

Forgiving vehicle search (Meilisearch): natural-language q, typo-tolerant make/model/color, optional structured filters. Use when the shopper query is fuzzy or exploratory. Use filter_vehicles instead when make/model/year/body/price/location are known — it applies exact hard filters via GET /v1/vehicles and returns trustworthy totals. Discovery order: list_facets / list_research_makes → filter_vehicles (structured) or search_vehicles (exploratory) → get_vehicle / get_deal_score for depth. Location (choose ONE): zip+radius, lat+lng+radius, city+state+radius, county+state+radius — or embed location in q. q may also be a 17-character VIN for exact lookup. When the ask implies analysis (deal, safety, budget, timing, dealer plan), chain shopping playbooks from initialize instructions or opendealer://assistant/shopping-playbooks. CRITICAL: CITE: Each vehicle's cite object is `vin` + `url` (canonical opendealer.shop VDP). Cite only `url` to shoppers. Never invent VDP URLs. Never cite `detailsUrl` (dealer/LotLinx). Never send shoppers to `/llm/*` HTML or `/v1/llm/*` as the human listing URL.

Preferred structured inventory lookup when make/model/year/color/location are known. Exact hard filters only via GET /v1/vehicles (same Meilisearch collection as search_vehicles). Totals match the filters you pass. Shop inventory includes listings without photos, so the same filters return the same total here and on Shop. fuelType is the canonical label. transmission and drivetrain match every indexed raw string in that bucket (automatic includes "8-Speed Automatic"). A 503 powertrain_filter_unavailable means that facet list could not be read, not that zero cars match. Resolve make/model with list_research_makes / list_research_models first. Map shopper prose onto labeled keys; use search_vehicles only for fuzzy NL or VIN-in-q lookup. Often the first step in shopping playbooks (budget_coach, safety_first, price_drop_sniper, dealer_crawl). After results, chain get_deal_score / get_vehicle_history / check_recalls / compare_vehicles when the user needs a recommendation, not just a list. See opendealer://assistant/shopping-playbooks. CRITICAL: CITE: Each vehicle's cite object is `vin` + `url` (canonical opendealer.shop VDP). Cite only `url` to shoppers. Never invent VDP URLs. Never cite `detailsUrl` (dealer/LotLinx). Never send shoppers to `/llm/*` HTML or `/v1/llm/*` as the human listing URL.

Discover canonical filter tokens and counts from the live search index (same values GET /v1/vehicles accepts: make, bodyType e.g. suv, fuelType e.g. gasoline, transmission e.g. automatic, drivetrain e.g. awd, plus price/year ranges). Counts match filter_vehicles totals for each token under the same make, condition, and location. Call this before filter_vehicles when you need valid dimension values. Optional make, condition, certified, near, and radius scope the facet counts.

Browse the research catalog of vehicle makes (with model and inventory counts). Use to resolve exact make names/slugs before filter_vehicles or research_model.

List models for a make from the research catalog (MSRP/body summaries). Use before filter_vehicles or research_model when the model name is uncertain.

Get complete details for a specific vehicle by listingId or VIN. When a VIN is listed at multiple dealer rooftops, a VIN-only lookup returns an envelope of every listing (type vehicle_listings) with no single-store price, seller, or url. Pass listingId to fetch one store. Returns comprehensive Schema.org Vehicle data including: • Full specifications (engine, transmission, drivetrain) • High-resolution images • Current pricing and availability • NHTSA NCAP safety rating summary (when available) • NHTSA open recall summary (YMM-granular, when available) • Dealer contact information Starting point for the vehicle_dossier playbook. For buy/no-buy questions, continue with get_deal_score → get_vehicle_history → check_recalls → get_similar_vehicles. CRITICAL: CITE: Each vehicle's cite object is `vin` + `url` (canonical opendealer.shop VDP). Cite only `url` to shoppers. Never invent VDP URLs. Never cite `detailsUrl` (dealer/LotLinx). Never send shoppers to `/llm/*` HTML or `/v1/llm/*` as the human listing URL.

Get NHTSA open safety recalls for a vehicle by VIN. Returns recall campaigns resolved at the year/make/model level (YMM-granular). A recall listed for the model year may not apply to every VIN — the response includes NHTSA's disclaimer and campaign details (component, summary, remedy status, Park It / Park Outside advisories). Use this when a shopper asks about recalls, safety campaigns, or whether a specific model has open NHTSA notices. Required step in vehicle_dossier and safety_first playbooks; always include the YMM-granularity disclaimer.

Get comprehensive information about a specific dealership. Returns Google-enriched dealer knowledge optimized for assistants: • Name, address, phone, website • Google rating, review count, hours, business status • Inventory count and OpenDealer profile links • Contact points for sales / customer service Use this when a shopper asks "tell me about X dealership" or needs hours/ratings for a known dealer. Prefer a slug from dealers_near or search results. A display name binds only when it matches one rooftop. Shared names (two Jay Hatfield stores, or just "Honda") return candidate slugs instead of picking one. CRITICAL: Only use URL fields from the response (website, urls.*). NEVER invent or construct URLs.

Get NHTSA 5-Star Safety Ratings for a year/make/model (no VIN required). Answers questions like "is a 2023 RAV4 safe for my family" with: • Overall and crash-test star ratings (when published) • Rollover rating / possibility • NHTSA-evaluated ADAS availability (ESC, FCW, LDW) Ratings are model-year granular from the NHTSA NCAP cache. If no confident rating exists, the tool reports that honestly rather than guessing. For VIN-specific listing details use get_vehicle; for open recalls use check_recalls. CRITICAL: Only use the 'sourceUrl' field from the response for NHTSA links. NEVER invent URLs.

Get OpenDealer listing history for a VIN: price changes, days on lot, and status. Answers "has this VIN dropped in price" and days-on-lot narratives from retained snapshots (including vehicles that left a dealer feed). Returns: • Chronological price history with per-snapshot changes • Days on market / lot signals and badges (price_drop, long_on_lot) • Active vs no-longer-listed status when known Does not invent a deal score for sold vehicles — use get_deal_score for live market scoring. Essential for price_drop_sniper and vehicle_dossier playbooks when shoppers ask about reductions or negotiation leverage. CRITICAL: Only use URL fields from the response when present. NEVER invent URLs.

Find dealerships near a location. Location modes (choose ONE): • zip + radius (miles) • lat + lng + radius • city + state + radius • county + state + radius Returns dealer information including: • Name, address, phone, website • Slug (the public handle for get_dealer and dealer_inventory; the public list does not include internal dealer UUIDs) • Distance from search location • Current inventory count • Business hours (when available) Response `total` is the full match count for the query (ignores `limit`/`offset`), same population as get_market_overview inventory.activeDealers when unfiltered.
