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, OpenClaw, Hermes Agent, 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

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.

Install in Claude (Desktop & Web), Recommended

Zillow MCP works with Claude Desktop and Claude Web.

Settings → Connectors → Add custom connector → paste:

https://api.zillapi.com/mcp

Claude runs the OAuth sign-in for you, no API key needed.

Prefer a key, or running headless? Add to claude_desktop_config.json instead:

{

"mcpServers": { "zillapi": { "transport": "streamable-http", "url": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in Claude Code (CLI)

Zillow MCP works with Claude Code.

claude mcp add --transport http zillapi https://api.zillapi.com/mcp \

--header "Authorization: Bearer zk_YOUR_KEY_HERE"

Install in ChatGPT

Zillow MCP works with ChatGPT (Developer Mode).

1. Enable Developer Mode: Settings → Apps & Connectors → Advanced settings.
2. Go to Settings → Connectors → Add MCP server (Create in the Connectors panel).
3. Paste the server URL:

https://api.zillapi.com/mcp

1. Complete the OAuth sign-in when prompted, no API key needed.

Install in Hermes Agent

Zillow MCP works with Hermes Agent.

Add to ~/.hermes/config.yaml under mcp_servers, with OAuth (no key handling):

mcp_servers:

zillapi: url: "https://api.zillapi.com/mcp" auth: oauth

Or with an API key:

mcp_servers:

zillapi: url: "https://api.zillapi.com/mcp" headers: Authorization: "Bearer zk_YOUR_KEY_HERE"

With auth: oauth, Hermes runs the MCP OAuth 2.1 flow (metadata discovery + dynamic client registration) automatically, this server supports it out of the box.

Install in OpenClaw

Zillow MCP works with OpenClaw.

With OAuth (no key handling):

openclaw mcp add zillapi --url https://api.zillapi.com/mcp --transport streamable-http --auth oauth

openclaw mcp login zillapi

Or with an API key:

openclaw mcp set zillapi '{"url":"https://api.zillapi.com/mcp","transport":"streamable-http","headers":{"Authorization":"Bearer zk_YOUR_KEY"}}'

Both write to ~/.openclaw/openclaw.json under mcp.servers:

{

"mcp": { "servers": { "zillapi": { "url": "https://api.zillapi.com/mcp", "transport": "streamable-http", "auth": "oauth" } } } }

Prefer skills over MCP? Zillapi is also available as an OpenClaw-ready agent skill, grab it at ZeroPointRepo/zillow-skills.

Install in Cursor (One-Click / Manual)

Or manually, add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{

"mcpServers": { "zillapi": { "url": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in VS Code (GitHub Copilot agent mode)

Or from the command line:

code --add-mcp '{"name":"zillapi","type":"http","url":"https://api.zillapi.com/mcp","headers":{"Authorization":"Bearer zk_YOUR_KEY_HERE"}}'

Install in Cline

{

"mcpServers": { "zillapi": { "url": "https://api.zillapi.com/mcp", "type": "streamableHttp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{

"mcpServers": { "zillapi": { "serverUrl": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in Zed

In Zed settings.json:

{

"context_servers": { "zillapi": { "source": "remote", "url": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in Roo Code

{

"mcpServers": { "zillapi": { "type": "streamable-http", "url": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

In ~/.gemini/settings.json:

{

"mcpServers": { "zillapi": { "httpUrl": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in JetBrains AI Assistant

In Settings → Tools → AI Assistant → MCP:

{

"mcpServers": { "zillapi": { "url": "https://api.zillapi.com/mcp", "headers": { "Authorization": "Bearer zk_YOUR_KEY_HERE" } } } }

Install in OpenAI Agent Builder / Agents SDK

Add the server as a hosted MCP tool with the URL https://api.zillapi.com/mcp and an Authorization: Bearer zk_YOUR_KEY_HERE header (or let end users OAuth). Any framework that speaks streamable-HTTP MCP works the same way.

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.
