The address to paste
https://keighbor.com/mcp
MCP, the Model Context Protocol, is a standard way for an AI assistant to use outside tools. Ours is public and needs no sign-in. It only reads what this site already publishes, and it changes nothing anywhere.
Claude (claude.ai and the desktop app)
- Open Customize, then Connectors, and choose Add custom connector.
- Paste https://keighbor.com/mcp as the address, choose No sign-in, and press Add.
- In a chat, press + and switch Keighbor on under Connectors.
- On a Team or Enterprise plan, an owner adds it once under Organization settings, then Connectors, and everyone else presses Connect. The Free plan allows one custom connector.
Menus move around. If a step looks different, Anthropic's page on adding a custom connector has the current path.
ChatGPT (Plus, Pro, Business, Enterprise and Education)
- In Settings, turn on Developer mode.
- Create a new app or connector with https://keighbor.com/mcp as the address and No authentication.
- In a chat, add Keighbor from the tools menu and ask your question.
Menus move around. If a step looks different, OpenAI's page on developer mode has the current path.

}
}VS Code
- Add one entry to .vscode/mcp.json:
{
"servers": {

What it can answer
- Seller closing costs by state. Seller closing costs in any state: the transfer tax and who usually pays it, title custom, who runs the closing, and the property-tax proration.
- Estimate net proceeds from a home sale. A rough estimate of what you keep, the same arithmetic as our proceeds calculator.
- Home sale paperwork for a state. The documents a sale in your state commonly involves, and who usually produces each one.
- What catches sellers out in a state. The rules that surprise sellers in a state, each with its citation.
- Real estate glossary lookup. What a real estate word means, with an example.
- Home selling timeline. The stretches of a sale laid out as dates, from the day you want to close or to list.
- Home selling checklist. Every step of a sale in order, each linked to its guide.
- Search Keighbor's guides. Our guides, articles and tools on a topic, with links.
Every answer comes from the same research as our pages: closing costs by state, paperwork by state, what catches sellers out, the glossary, the timeline and the guides. Each one names its page so you can read the whole thing.
What it is not
It describes what is typical and what the research says. It does not look up your home, see your Room, or tell you what to do about your sale. Keighbor is a software company, not a law firm, brokerage, or tax adviser. This is general information, not legal, tax, financial, or real estate advice about your sale. Your situation may differ. Before acting on a contract, disclosure, title, tax, or pricing question, ask an appropriately licensed professional in your state.
What we receive
Only what your assistant sends to run a tool: a state, a price, a date or a word. We use it to work out the answer and keep none of it, and each network address can only call it so often. The privacy policy says the same thing formally.
