What you get

One plugin, three kinds of superpowers, zero configuration:

Component	What it does
MCP server (zillapi)	4 hosted tools — lookup_property_by_address, lookup_property_by_zpid, get_zestimate, search_listings — over streamable HTTP with OAuth 2.1. No key handling: your agent signs you in on first use.
Skill (zillow)	Teaches the agent when to reach for property data, which tool is cheapest, and how to build search bounding boxes — so plain-English questions just work.
Slash commands	/zillow:property · /zillow:zestimate · /zillow:search · /zillow:comps — one-line workflows for the things you do all day.

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

Any Open Plugins-compatible agent

This repo follows the Open Plugins standard (.plugin/plugin.json, skills/, commands/, .mcp.json) — install it with your tool's plugin mechanism, pointed at this repository.

Authentication — OAuth, not keys

The bundled MCP config is exactly this:

{
  "mcpServers": {
    "zillapi": {
      "url": "https://api.zillapi.com/mcp"
    }
  }
}

No token, no env var. 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

Tool	Cost
lookup_property_by_address	3 credits
lookup_property_by_zpid	1 credit (24 h cache)
get_zestimate	1 credit
search_listings	1 credit per listing returned

Plan	Price	Credits	Rate limit	Top-ups
Free	$0	100 (one-time)	20/min	not available
Monthly	$5/mo	1,000/month	200/min	$4 per 1,000
Annual	$54/yr	12,000 upfront	300/min	$3 per 1,000

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).
