ChatGPT has over 300 million weekly active users. And as of early 2026, paid subscribers can connect it to external data sources through MCP, which means you can now search live Austin MLS listings, pull sold comps, and check market stats right inside the same tool you probably already use to draft emails and plan vacations. The same property data displayed on NeuhausRE.com, just delivered through ChatGPT instead of a web browser.
Sounds complicated right. It is not. The setup takes about two minutes, and once connected you can ask things like “show me homes in Lakeway under $800K” or “what sold in 78738 last month” and get actual MLS results back. Not web scrapes from aggregator sites. Not Zillow estimates. Real listing data from the Austin MLS MCP connector we built at Neuhaus Realty Group.
Lets walk through how to set it up.
What ChatGPT Developer Mode Actually Is
Ok so ChatGPT has this feature called Developer Mode. It is in beta right now and it lets you connect ChatGPT to external tools and data sources through something called MCP (Model Context Protocol). I wrote a full explainer on what MCP means for real estate if you want the deep dive. But the short version: MCP is a standard that lets AI tools query live databases directly. Instead of ChatGPT only knowing what it was trained on (which is already months out of date by the time you ask), it can reach out and pull fresh data in real time.
Developer Mode is available to ChatGPT Plus, Pro, Team, Enterprise, and Edu subscribers. If you are on the free plan, this one feature alone might be worth the upgrade. The Plus plan runs $20/month and gives you access to Developer Mode along with the better models and faster responses.
The way I think about it, and Peter Thiel made this argument in Zero to One, the most valuable tools connect things that were previously separate. Your AI assistant on one side. Live property data on the other. MCP is the bridge. And ChatGPT being the biggest AI platform on the planet means this bridge reaches more people than any other client we support.
What You Get When Connected
When you connect the NeuhausRE MCP connector to ChatGPT, you unlock four tools that ChatGPT can call during any conversation:
search_listings. Find active listings by city, zip code, neighborhood, price range, beds, baths, square footage, and property features. You just ask in plain English and ChatGPT figures out which parameters to use, no big deal right.
get_listing. Pull the full details on a specific property. Photos, descriptions, tax records, HOA info, school assignments. Everything the MLS has on file.
get_comps. Closed-sale comparables by address, radius, and date range. This is the same data agents use when pricing homes, and it is available through the Active Buyer tier.
get_market_stats. Median prices, inventory levels, days on market, price per square foot trends by city or zip code. Also Active Buyer tier.
The thing that makes ChatGPT different from our Cursor connector or Claude connector is the audience. Cursor is for developers writing code against property data. Claude is for deep analysis and long strategy conversations. ChatGPT is where most people already live. If you use ChatGPT for work, for research, for planning a move, adding Austin real estate data just means one less tab you have to keep open.
Step-by-Step: Connecting ChatGPT to Austin MLS Data
Here is the actual setup. I am going to walk through this like I would if you were sitting across from me.
Step 1: Open Your Connectors Settings
Log into ChatGPT on the web (this does not work on mobile yet) and go to Settings. Look for Connectors in the left sidebar. If you do not see it, make sure you are on a paid plan (Plus, Pro, Team, Enterprise, or Edu).
Step 2: Enable Developer Mode
Inside the Connectors settings, click Advanced settings. You will see a toggle for Developer Mode. Flip it on. ChatGPT will show you a warning that Developer Mode lets you connect to unverified servers. That is fine. Our MCP server runs on HTTPS with OAuth authentication, which is the same security standard ChatGPT uses for its own built-in connectors.
Step 3: Create the Connector
Go back to the main Connectors page. You should now see a Create button in the top-right corner (it only appears after Developer Mode is enabled). Click it and fill in these fields:
- Name: Austin MLS
- Server URL:
https://mls.neuhausre.com/mcp - Description: Live Austin MLS listings, comps, and market data from NeuhausRE.com
- Authentication: OAuth 2.0
Check the trust acknowledgement box and click Create. That URL is the same endpoint used by Claude Desktop, Cursor, Perplexity, and every other MCP client we support. One server, works everywhere.
Step 4: Authorize
The first time ChatGPT connects, it will kick off an OAuth flow. You will see a quick signup form asking for your name, email, and phone number. Fill it out, authorize, and you are done with the one-time setup.
Step 5: Enable in Your Chat
This is the part people miss. After creating the connector, you need to activate it in each new conversation. Open a chat, click the + button in the message bar, click More, then Developer Mode, and enable your Austin MLS connector. Once enabled, it stays active for the whole conversation.
I know that is one more click than it should be (OpenAI is still polishing the UX here, it is beta after all). Not going to lie, I had to do it three times before I remembered the sequence. But once you do it you can start asking questions about Austin real estate and ChatGPT will pull live data from our MLS server automatically.
Example Queries to Try
So you are connected. Now the fun part. Here are some real prompts that work. These are the kinds of questions I ask myself when working with buyers or evaluating a deal.
Searching for homes:
- “Show me homes in Lakeway under $800K with at least 3 bedrooms”
- “What is available in Bee Cave with a pool and more than 2,500 square feet?”
- “Find listings in 78738 between $500K and $750K that have been on the market more than 21 days”
- “Are there any new construction homes in Dripping Springs under $600K?”
Pulling comps (Active Buyer tier):
- “What sold within half a mile of 15900 Hamilton Pool Rd in the last 6 months?”
- “Show me closed sales in Westlake over $2M this year”
Market stats:
- “What is the median home price in 78746 right now?”
- “Compare days on market between Lakeway and Bee Cave”
- “How much active inventory is there in Dripping Springs?”
And here is where ChatGPT’s general knowledge becomes an advantage. You can blend property queries with broader questions in the same conversation. Ask “show me 4-bed homes in Bee Cave under $900K and tell me about the school district” and ChatGPT will pull real listings from our MLS server alongside school information from its training data. That combination is genuinely useful if you are researching from out of state and trying to narrow down neighborhoods, which honestly is like half the people who call me these days.
I recently worked with a family relocating from Chicago who did exactly this. They spent a weekend running queries in ChatGPT, combining our listing data with questions about commute times, property taxes, school ratings. By the time they called me, they already had a shortlist of three neighborhoods. We skipped most of the discovery phase and went straight to touring homes. That is what happens when someone starts with real data instead of scrolling through a chatbot that demands your phone number before it shows you anything useful.
Who This Is For (And Who It Is Not For)
Lets be direct about this.
People who already use ChatGPT Plus or Pro. You are paying for it anyway. Adding a data source takes two minutes. If you are even casually curious about Austin real estate, whether you are thinking about moving here or you already live here and want to keep tabs on your neighborhood, this is the lowest-friction way to get real data.
Relocators doing homework. You are the kind of person who researches everything before making a decision. You are moving to Austin from somewhere else and you want to understand the market before you ever talk to an agent. This gives you that. Real MLS listings, not whatever Zillow’s algorithm decided to show you today.
Investors who want to run their own numbers. You want comps, market stats, and listing data you can analyze yourself. The Active Buyer tier gives you that. And when you are ready to move on a deal, I am right here.
Who this is NOT for. If you are on ChatGPT’s free plan, you cannot access Developer Mode. You would need to upgrade to at least Plus ($20/month). And if you want to write code against the property data (build scripts, automate analysis), the Cursor setup is probably a better fit. ChatGPT is conversational. Cursor is for developers.
Free Access and the Active Buyer Retainer
The NeuhausRE MCP connector has a free tier and a paid tier. Same structure regardless of which AI client you use.
Free tier. Search active listings right now, no cost, no credit card. You get 10 results per search, 10 queries per hour, and 100 per month. That is plenty for exploring neighborhoods, browsing what is on the market, and getting a feel for prices. If you are just curious, start here.
Active Buyer tier ($200/month). This is a buyer’s agent retainer with me at Neuhaus Realty Group. When you sign a buyer representation agreement, you get full MLS access including sold comps, market stats, saved searches, higher query limits (50 results per search, 200 per hour, 10,000 per month), and of course, me. Nineteen years of Austin market experience, property tours, offer strategy, negotiations, everything that comes with having a dedicated agent. The $200 is credited toward your closing costs if you purchase through us, so if you end up buying you effectively paid nothing.
I want to be clear about what this is. The free tier is a tool. The Active Buyer tier is a professional relationship with a real estate agent. You are not buying data. You are working with me, and the enhanced MLS access is part of that relationship.
Why ChatGPT Matters More Than the Other Clients
We built MCP connectors for Claude, Cursor, Perplexity, and several other AI tools. The full list is on the main connector page. Same MCP server, same endpoint, same data. So why does ChatGPT matter more?
Scale. Three hundred million weekly users is not a niche. Claude, Cursor, and Perplexity are fantastic tools but they each serve a specific audience. Developers, researchers, power users. ChatGPT is where everyone else already is. Your neighbor who asks ChatGPT what to make for dinner is also going to ask it about homes for sale in their zip code. When that happens, having real MLS data plugged in means they get actual listings instead of whatever ChatGPT can cobble together from its training data.
Seth Godin’s whole framework is about meeting people where they already are. Not asking them to learn a new tool or download another app. Just adding value to the thing they are already using. That is exactly what this is.
And honestly it is good for my business. The people who take two minutes to connect a data source to their AI tool are not tire kickers. They are researchers. Analyzers. The kind of buyers who show up to a meeting with a spreadsheet and know exactly what they want. Those are my favorite clients. We tend to get along pretty well.
Frequently Asked Questions
Ready to Connect?
The setup is genuinely two minutes. Go to Settings, enable Developer Mode, create a connector with https://mls.neuhausre.com/mcp, authorize, and start asking questions about Austin real estate. If you run into anything during setup or want to talk about what you are finding in the data, reach out to me directly. I built this because I think the best way to find a home is to start with real data, not a popup quiz. And the people who connect AI tools to live databases tend to be the exact kind of client I work best with.
The full list of supported AI clients and setup guides is on the Austin MLS MCP connector page.
Be safe, be good, and be nice to people.
