Listing and MLS MCPs: what they do and who makes them
A listing MCP connects Claude or ChatGPT to homes for sale or rent. Ask, and it searches listings, pulls details and checks price history.

What a listing MCP does
Ask in plain English:
- "Three-bedroom homes under $250,000 in Memphis listed in the last week."
- "What's the price history on 1820 Oak Ridge Drive?"
- "How many days on market do homes in 38116 average right now?"
- "Compare these three listings side by side."
Zillow's official Claude connector
Zillow launched an official Claude connector in October 2026. Claude can search listings, pull home details and Zestimates, and link to each listing.
It's free and covers listed homes only. More on our Zillow MCP page.
MLS MCPs: Trestle, Flexmls and Repliers
MLS data is licensed. A server works only if your MLS turned it on and you're a member, or you pay a licensed reseller.
More on MLS access on our MLS MCP page.
Scrapers and their risks: community portal servers
GitHub has a dozen or so community servers for Zillow, Redfin and Airbnb. Examples:
| Server | What it reads | How |
|---|---|---|
| chrischall/zillow-mcp | Zillow search, details, Zestimate history, saved searches | Through your own signed-in zillow.com tab |
| chrischall/redfin-mcp | Redfin search, details, market reports | Through your own signed-in redfin.com tab |
| Marius-Juston/redfin-mcp | Fork of the above, adds rental comps | Same |
| sap156/zillow-mcp-server | Zillow data | Needs an approved Zillow Bridge API key |
| openbnb-org/mcp-server-airbnb | Airbnb listings, for short-term rental research | Reads Airbnb's public site |
| abracadabra50/open-properties | Searches and deduplicates listings across portals | Open-source CLI and server |
The risk: most portals don't allow automated access in their terms. A server can break when the site changes, and heavy use can get you blocked.
Fine for personal research, but don't build a business process on one. More on Redfin on our Redfin MCP page.
Same prompts, two servers
We ran three prompts through Zillow's Claude connector and Repliers' free preview:
- "Homes for sale in [market] under $250,000 with 3+ bedrooms."
- "Price history for [address]."
- "Median days on market in [zip] this month."
| Prompt | Zillow connector | Repliers (preview) |
|---|---|---|
| Search under $250k | [fill from test] | [fill from test] |
| Price history | [fill from test] | [fill from test] |
| Days on market | [fill from test] | [fill from test] |
What listing data can't tell you
Listing MCPs answer "what's for sale?" well. For investors, that's the problem.
- A listed home is already marketed. Every buyer and agent in town sees it, and the price reflects that.
- The seller already has an agent. You compete on price instead of solving a problem.
- The best deals often never get listed. Owners behind on payments, heirs and tired landlords often sell before or instead of listing.
Where off-market data comes in
Seller signal MCPs read public filings: pre-foreclosure, probate, tax delinquency, code violations, liens, evictions, divorce, vacancy. They answer "who might need to sell?" instead of "who's selling?"
Questions
Is there a free listing MCP? Yes, Zillow's Claude connector is free.
Can I get MLS data into ChatGPT or Claude without being an agent? Usually not directly, because MLS data is licensed to members.
Do listing MCPs include off-market homes? No, only homes listed for sale or rent.
