MLS Data AI Property Search New Features 2026: What Actually Launched
If you don’t want to read the whole guide or have difficulty reading, you can listen to this guide instead.
The mls data ai property search new features 2026 story is scattered across launch announcements. No single roundup pulls the year together. This article does, using the announcements and trade coverage themselves.
Three patterns run through almost every launch. AI assistants now sit inside the agent’s MLS workspace, not just on public portals.
A standard called MCP became the pipe that connects listing data to outside AI tools. And nearly every agentic feature ships with a human approval step.
AI Holic covers launches like these across our AI for Business section. Company scale figures below are the companies’ own, and vendor claims are labelled as claims.
The 2026 Launches at a Glance
| When | Who | What is new |
|---|---|---|
| January 2026 | ATTOM | MCP server opens its property database to AI clients |
| March 2026 | Cotality | MCP server for property data with climate risk assets |
| June 2026 | Realtor.com | RealAssist AI launches as a conversational home search |
| October 2026 | Realtor.com | RealAssist AI added to the Realtor.com+ agent workspace |
| October 2026 | Solid Earth | Recursive MLS platform and Recursive AI announced |
| October 2026 | EasyAgentIDX | IDX search platform with read-only MCP connections |
Underneath the table sits one shared asset: the multiple listing service database itself. Every feature below is a new way to search it, summarize it, or connect it to an AI assistant. The data did not change; the doors into it did.
Realtor.com Puts RealAssist AI Inside the Agent Workspace
Realtor.com+ is a collaborative search platform that agents get only through their MLS, as a member benefit. It launched in early 2026. Inside it, agents search with full MLS filters, watch buyer search activity in real time, and auto-plan tour routes.
RealAssist AI arrived in that workspace in October 2026, after first launching in June. Per the announcement covered by Inman, it does three jobs. It sets up clients and their searches from captured preferences and notes, it sends a Daily Digest of each client’s chats, searches, notifications, and price changes, and it takes supervised actions.
Those actions include refining searches with professional-level MLS data fields and drafting client messages in the agent’s tone. Every action waits for the agent to review and approve it first. An RPR integration also brings Realtors Property Resource market trends into the same screen.
The scale figures are Realtor.com’s own, from its release. The platform is live in 21 markets with four more coming, and adoption reaches up to 10 percent of agents in live markets. The company counts more than 192,000 agents and nearly 252,000 listings on it.
The Buyer Side: Conversational Search Built With Gemini
The same RealAssist name fronts the consumer launch from June 2026. Realtor.com’s release says the buyer-facing assistant was built with Google’s Gemini and Google Cloud. It lets shoppers search in natural conversation instead of filter boxes.
The release describes multi-part requests handled in one chat, covering budget, commute, and property features together. It first opened in beta to a select group of signed-in users. The agent workspace version above is the professional counterpart, grounded in MLS data rather than public listings alone.
Solid Earth Rebuilds the MLS Platform Itself
Solid Earth used the RESO Fall Conference in October 2026 to announce three products at once. They are the Recursive MLS platform, an association management system, and Recursive AI. The details below are the company’s own launch claims.
The company says listing data stays in the MLS’s own cloud account, in an open format, with no extra data access fees. It describes its custom model as the first LLM built exclusively for MLSs. An AI layer it calls a harness enforces MLS data rules while approved outside systems connect.
Two features target daily agent work. Listing entry can start from an address and auto-fill up to 80 percent of fields from public records and past sales, per the company. Its Safe AI Assistant searches listings in natural language across multiple MLSs, builds market reports, and hides private agent notes.
EasyAgentIDX Connects Agent Websites to AI Clients
EasyAgentIDX launched in October 2026 as an IDX platform for agent and brokerage websites. Per its announcement, it provides search widgets, listing grids, interactive maps, and affordability calculators. It supports WordPress, Wix, Squarespace, Webflow, Framer, and custom sites.
The AI angle sits in its higher plans. Pro, Brokerage, and Enterprise plans include read-only MCP connections, so approved account data such as listings, leads, and saved activity can be reached from AI clients like ChatGPT and Claude. A separate product, ChatSpark, lets site visitors describe a home and refine the search in conversation.
MCP Became the Standard Pipe for Property Data
The year’s quietest change may matter most. MCP, short for Model Context Protocol, is the standard that lets AI assistants query outside databases directly. Real estate data providers spent 2026 plugging into it, per a research guide from ChatForest.
ATTOM opened the run on January 29, 2026, described by trade press as the first large data licensing company in real estate to launch an MCP server. Its coverage was stated at 158 million US properties at launch, and its own page now says more than 160 million. Access is commercial and needs an ATTOM API key.
Cotality, formerly CoreLogic, followed on March 31, 2026. Its server connects AI clients to property data with CLIP property IDs and climate risk assessments. MLSs moved too: UtahRealEstate.com was the first MLS to announce its own MCP server, back in September 2025, and NorthstarMLS was reported close behind.
Open options exist alongside the commercial ones. The same guide lists a BatchData server covering more than 155 million properties under an MIT license, and a community Zillow server that works through the Zillow Bridge API. Our SaaS hire versus outsource versus AI guide covers the build-or-buy side of shifts like this.
Frequently Asked Questions
What is the biggest MLS AI change in 2026?
Two changes share the claim. Agent workspaces gained supervised AI assistants, led by RealAssist AI inside Realtor.com+. And MCP became the standard way AI tools reach MLS and property data, with ATTOM and Cotality both launching servers.
Can ChatGPT or Claude search MLS data now?
Through MCP connections, yes, within limits. EasyAgentIDX offers read-only MCP access to account data on its higher plans.
Data providers like ATTOM and Cotality sell access to their own databases. None of this is open public access to a full MLS.
Do these AI features act without an agent?
Not in the launches covered here. Realtor.com states that RealAssist AI actions wait for agent review and approval.
Solid Earth frames its guardrails as an enforcement layer for MLS rules. Human sign-off is the consistent design choice of 2026.
How much do these new features cost?
The announcements covered here state no prices. Realtor.com+ reaches agents as an MLS member benefit, and ATTOM describes its data access as commercial with an API key. Anything more specific would be a guess, so this roundup prints none.
Conclusion
The mls data ai property search new features 2026 story is about access, not new data. Assistants moved into the agent’s workspace, MCP standardized the connection, and approval steps kept agents in control of every action.
