MLS API Canada: Plug Live BC Listings Into ChatGPT and Claude (MCP)

What the Zealty MCP server exposes

Four tools today, each wrapping a slice of the BC MLS data that powers zealty.ca.

• search_listings. Active, sold, and expired listings across British Columbia with the full Zealty filter set: price, beds, baths, square feet, lot size, building age, maintenance fee, open house day, court-ordered sales, biggest price cuts. Example: "Find detached houses in North Vancouver under $2M with at least three beds."
• get_market_stats. Active inventory snapshot for any BC region: count of listings, median price, price per square foot, days on market. Optional historical trends up to 60 months. Example: "How has the Coquitlam condo market changed over the last year?"
• get_price_distribution. A bucketed price histogram from $0 to $20M+ for any region, with the same filters as listing search. The right tool for "what do prices actually look like" questions.
• get_neighborhoods. Valid neighbourhood names for a city or region so follow-up searches can be scoped tightly (Yaletown, Kitsilano, Metrotown). Mostly a helper for the other tools.

Every listing result includes a clickable zealty.ca URL, so the assistant does not have to fabricate links and you can jump from chat to the full listing page in one click.

Connect Claude, ChatGPT, or Cursor in two minutes

Claude Desktop supports MCP servers as Connectors. Open Settings, Connectors, Add Custom Connector, and paste the endpoint URL:

https://www.zealty.ca/api/mcp

That is the whole config. Active listings, market snapshots, neighbourhoods, and price distributions need no sign-in. For sold or expired history, Claude will walk you through a one-time Google OAuth handshake the first time it calls those tools.

Claude Code, the developer terminal client, takes a one-liner:

claude mcp add --transport http zealty https://www.zealty.ca/api/mcp

ChatGPT, Cursor, and other MCP-aware clients accept the same URL in their MCP server settings. The endpoint speaks standard streamable HTTP, so anything that complies with the spec should connect on the first attempt.

Plain-English queries that work today

Once Zealty is connected, you do not need tool names or filter codes. Ask in plain English. A few queries British Columbia buyers and developers have already been running:

• "Find the five biggest price cuts on active apartments in the City of Vancouver this month."
• "What is the median asking price for a two-bedroom condo in Burnaby right now, and how has it moved over the last 12 months?"
• "Show me townhouses in South Surrey under $1.3M built in the last 10 years."
• "How many active foreclosure listings are there in Metro Vancouver, and what is the price spread?"
• "Compare median price per square foot for apartments in Coquitlam, Port Coquitlam, and Maple Ridge."

Behind the scenes the assistant hits the same tRPC search and stats endpoints that power the Zealty map search and the monthly market statistics pages. The numbers in chat match what you would see on the site.

What needs sign-in, and why

A subset of Zealty data sits behind a free account: sold prices, expired listings, and historical monthly trends. Those are licensed datasets, so the MCP server mirrors the same authentication boundary that already exists on the website.

Auth is standard OAuth 2.1 with Google as the identity provider, the same sign-in used on zealty.ca. The first time your assistant calls a gated tool, it redirects you through a browser handshake, stores the token in the client, and reuses it. Anonymous queries against active listings, neighbourhoods, and the current inventory snapshot work with no setup at all.

Privacy, rate limits, fair use

The endpoint is rate-limited per IP at the load balancer, so a runaway agent in a loop gets stopped quickly. MCP traffic is logged the same way the rest of the site is logged, never shared with third parties, and never used to train models on user prompts. The endpoint is read-only: no Zealty tool over MCP can change account data, save a search, or write back to a lead profile.

What is coming next

This is version one, and the tool surface will grow. On the short list: the Strata Browser for our 14,000+ BC strata building profiles, AI-powered OfferValue and OfferRent estimates from Offerland, and a dedicated court-ordered sale tool for foreclosure hunters. We are also working on a richer map widget that ChatGPT and Claude can embed in chat directly, so you see pins and prices inline instead of a list of links.

If you build with MCP, the endpoint is open and standards-compliant. Pair it with a coding agent and you can prototype a BC-specific real estate tool in an afternoon. If you simply want a faster way to research a purchase, add the connector to whichever AI assistant you already use and start asking.

Try it today

Point your AI assistant at https://www.zealty.ca/api/mcp and ask it the most painful research question on your current home search. Then come back to Zealty for BC listings to dig into the ones the assistant surfaced. We would love to hear which questions worked, which fell short, and what we should expose next.
