MLS MCP servers: what's available and who can use them
Yes, an MLS MCP can now connect MLS data to Claude, ChatGPT and other AI. The big MLS platforms launched servers in 2026, and Repliers has one too.
The short answer
The catch: you need an MLS license, or MLS approval, to use the data. An MCP server is a new door to the same data, under the same rules.
The MLS MCP servers that exist today
| Server | Who it's for | Notes |
|---|---|---|
| Cotality Trestle MCP | MLS organizations on the Trestle platform, and the AI apps they approve | Announced October 2026, at no extra cost to the MLS. Paired with Trestle Defender for licensing control. |
| Flexmls MCP Server (FBS) | MLS organizations and their subscribers | Launched April 2026. |
| Repliers MCP Server | Licensed agents, brokerages and approved vendors using Repliers' MLS feeds | Hosted at mcp.repliers.io, or self-host the MIT-licensed version. |
| Cotality MCP Server (not MLS) | Licensed Cotality customers | Property, valuation and risk data rather than MLS listings. Launched March 2026. |
To browse listings in a chat without an MLS license, Zillow's official Claude connector and ChatGPT app are free. See Zillow MCP and all listing and MLS MCPs.
Who can get MLS access
MLS data belongs to the MLS and its participants, and each MLS sets its rules. In general:
- Licensed agents and brokers get access through their MLS membership.
- IDX is for showing listings to the public on a website.
- Technology vendors need their own license from each MLS whose data they use.
- AI use is decided by the MLS.
- Access stops if your license lapses.
If you're an investor, not an agent
Many investors and wholesalers aren't MLS members, so an MLS MCP may be out of reach. It also targets listed homes, not the off-market sellers below.
- pre-foreclosure and foreclosure filings
- probate cases
- tax delinquency, code violations and liens
- evictions, divorce and bankruptcy filings
- vacant homes and absentee owners

FAQ
Is there an MLS MCP server? Yes: Trestle MCP and Flexmls MCP serve MLS organizations and approved apps, and Repliers runs one.
Do I need a real estate license to use an MLS MCP? Usually, or MLS approval through membership or a vendor license, and each MLS decides what's allowed, including AI use.
Can I use MLS data in ChatGPT or Claude? Only if your MLS's data agreement allows it, since the license, not the server, makes it allowed.
