# Use West Kite in Claude and ChatGPT

West Kite is a remote MCP server for US commercial property ownership: owners of record, the people behind LLCs, and their phone numbers and emails. Sign-in is OAuth, so there's no API key, and the 7-day free trial needs no card.

The server is https://app.westkite.com/mcp. You need a West Kite account, and you can start a free trial if you don't have one. An agent without a browser can [start sign-up for its person](https://westkite.com/docs/agent-signup.md).

## Connect

- Claude or ChatGPT: choose Connect AI in West Kite and follow the steps. If your assistant asks for a server URL, use https://app.westkite.com/mcp.
- Coding agents such as Claude Code or Codex: read https://westkite.com/agent-quickstart.md and connect the MCP server. Then sign in to West Kite when asked and select Allow.

## What you can do

- Screen properties by place, type, size, sale date, value and owner, and read the evidence behind each one.
- Look up owners, sales, loans, permits, listings, businesses, brokers and market trends.
- Export a full result set as one file with an exact total and its sources. Export limits depend on your plan.
- See your Pipeline: deals, replies, call notes and what is waiting on you.
- Add owners to your Pipeline, save properties, draft outreach, start ownership research and write documents.

## Things to try

- What's waiting on me in my Pipeline today?
- Who owns 500 Howard St in San Francisco, and what did they pay?
- Find office buildings over 50,000 sq ft in Oakland held for more than 15 years.
- Export every retail property sold in the last 5 years in Fulton County, Georgia.

## Permissions

When your assistant wants to change something, it gives you a review link. Nothing changes until you approve it in West Kite, and nothing is ever sent from your assistant. To disconnect, open Connect AI in West Kite.

## What to expect

Coverage varies by county, and many states don't publish sale prices. West Kite shows what each source publishes and says when a field is missing. Each account can make 60 requests a minute.
