Zillow MCP Server — Property Data, Zestimates & Listings for AI Agents

Run comps, check home values, and scan listings by just asking your AI — live Zillow data on 160M+ U.S. homes. Try for free.
Four tools — property lookup by address, lookup by zpid, Zestimates, and listing search — for Claude, ChatGPT, Hermes Agent, OpenClaw, Cursor, Claude Code, and any MCP client.

160M+ U.S. properties · 300+ fields per home · hosted REST + MCP · free tier, no card Zillapi is an independent service for Zillow-sourced data — not affiliated with Zillow.

Why Zillow MCP

You run comps, check what homes are worth, and track listings all day. Zillow MCP puts that data inside the AI you already talk to.

Connect once, then just ask. Add Zillow MCP to Claude, ChatGPT, Cursor, or any MCP client a single time — and your AI assistant can pull live Zillow property data (full property records, Zestimates, and listings) right in the conversation. No code, no repeated setup.

Ask for comps on a subject property. Check a flip's numbers against its asking price. Pull rent estimates for a cash-flow check. Or just ask what a home is worth — Zestimate, taxes, schools, and full price history come back in seconds.

Quick taste:

Find 3-bed homes for sale under $600k in Washington DC,
pull the full record for the most promising one,
and check how its Zestimate compares to the asking price.

That single prompt uses 3 of the 4 tools — search_listings, lookup_property_by_zpid, get_zestimate — without you writing a line of code.

Quick Install

Requirements:

• A Zillapi account (sign up free — 100 credits free, no card)
• An API key (zk_...) from your dashboard OR just use OAuth (Claude, ChatGPT, Hermes Agent, OpenClaw — no key handling)

Recommended: add a rule to auto-invoke Zillow MCP

Add this rule to your AI client so you don't have to ask explicitly:

txt

Copy

When I mention a U.S. property address, a Zillow link, or ask about home
values, listings, or comps, automatically use the zillapi MCP tools to
fetch real property data before answering.

Authentication

Two ways in — both end at the same account and credits:

• OAuth 2.1 (recommended for Claude, ChatGPT, Hermes Agent & OpenClaw): paste the endpoint (or set auth: oauth) and sign in when prompted. The server implements Dynamic Client Registration, so DCR-aware clients discover everything automatically — you never touch a key.
• API key (zk_...): for key-based clients (Cursor, VS Code, Cline, scripts). Get one free at zillapi.com/signup and send it as Authorization: Bearer zk_....

Security note: treat zk_ keys like passwords — never commit them to a repo or paste them into shared configs. If a key leaks, revoke it in your dashboard and mint a new one.

FAQ

Is there a public Zillow API in 2026? Not an open one — Zillow retired its public API (ZWSID) in 2021, and official access now runs through Bridge Interactive, which is MLS-gated. Zillow MCP provides same-day, self-serve access to Zillow-sourced property data through the Model Context Protocol, with a free tier and no approval process.

What is a Zillow MCP? A Zillow MCP is a Model Context Protocol server that exposes Zillow property data as tools an AI agent can call: property lookup by address or zpid, Zestimates, and listing search, so assistants like Claude, ChatGPT, and Cursor can fetch live U.S. property data mid-conversation, backed by Zillapi's hosted property data API.

How do I add it to Claude Desktop, Claude Code, or ChatGPT? Claude Desktop: Settings → Connectors → Add custom connector → paste https://api.zillapi.com/mcp. Claude Code: claude mcp add --transport http zillapi https://api.zillapi.com/mcp --header "Authorization: Bearer zk_YOUR_KEY". ChatGPT: enable Developer Mode, then Settings → Connectors → Add MCP server → paste the URL and complete the OAuth prompt. See Quick Install for every client.

Can it run comps or a quick CMA? Yes — that's the core workflow. Ask for recently sold homes near a subject property, then compare sale prices, Zestimates, and price per sqft. Agents use it for quick CMAs; investors run the same flow for flip margins and rental yield checks.

How much does it cost? 100 free credits at signup with no card. After that it's credit-based — monthly/annual plans or top-ups from $4 per 1,000 credits. Most calls are 1 credit per record; address lookups are 3 credits; failed calls are free.

Is this affiliated with Zillow? No. Zillapi is an independent service and is not affiliated with, endorsed by, or sponsored by Zillow Group, Inc. "Zillow" and "Zestimate" are trademarks of Zillow Group, Inc., used here descriptively to refer to those services.
