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

What you get

One plugin, three kinds of superpowers, zero configuration:

Just ask, in plain English:

What's the Zestimate on 17 Zelma Dr, Greenville SC?
Find 3-bed homes for sale under $600k in Greenville SC.
Run comps for https://www.zillow.com/homedetails/…_zpid/

Or use a command:

/zillow:comps 17 Zelma Dr, Greenville, SC 29617

…and the agent pulls the subject property, searches recently sold homes around it, and hands back a comp table with an indicated value.

Install

Cursor

• Marketplace: browse cursor.com/marketplace or search "zillow" in the Customize panel, or
• In the editor: type /add-plugin and enter this repo:

https://github.com/ZeroPointRepo/zillow-plugin

First property question you ask, Cursor prompts a Zillapi OAuth sign-in (create a free account if you don't have one — 100 credits, no card). Done.

Claude Code

/plugin marketplace add ZeroPointRepo/zillow-plugin
/plugin install zillow@zillapi

VS Code

Command Palette → Chat: Install Plugin From Source, then paste:

https://github.com/ZeroPointRepo/zillow-plugin

Or register a local clone in settings.json:

"chat.pluginLocations": { "/absolute/path/to/zillow-plugin": true }

This repository root is a conformant Agent Plugins 1.0.0 package (plugin.json, skills/, mcp.json). Install it with your client's plugin mechanism pointed at this repository, or at a local clone.

Agent Plugins 1.0.0 standardizes the package format, not installation — each client owns its own install flow.

Any client

The plugin is just a directory. Clone it wherever your client scans for plugins:

git clone https://github.com/ZeroPointRepo/zillow-plugin

Authentication — OAuth, not keys

The bundled MCP config is exactly this:

{
  "$schema": "https://agent-plugins.org/schemas/1.0.0/mcp.schema.json",
  "mcpServers": {
    "zillapi": {
      "type": "streamable-http",
      "url": "https://api.zillapi.com/mcp"
    }
  }
}

No token, no env var — Agent Plugins 1.0.0 forbids embedded credentials, and authorization is client-managed by design. The server implements MCP OAuth 2.1 with Dynamic Client Registration: on the first (unauthenticated) request it answers 401 with discovery metadata, your client opens the sign-in flow, and from then on calls run under your Zillapi account. Sign up free at zillapi.com/signup — 100 credits, no card.

Credits & pricing

Failed calls don't consume credits. The skill and commands are written to keep spend low (zpid over address, tight bounding boxes, confirm before broad searches).

plugin.json + mcp.json + skills/ at the repo root are the portable Agent Plugins 1.0.0 package. The dot-directories are retained so existing installs on older client-specific formats keep working; new clients should use the root manifests.

curl -sO https://agent-plugins.org/schemas/1.0.0/plugin.schema.json
curl -sO https://agent-plugins.org/schemas/1.0.0/mcp.schema.json
