MCP connector
Nexa in ChatGPT and Claude
The Nexa connector gives Claude and ChatGPT access to your real estate agent workspace. Ask in the chat what is on your plate today, find a client, match listings to a buyer’s request or check deal prices in a neighbourhood — the assistant answers from your data in Nexa. For real estate agents and brokerages in Israel; Nexa has a free plan. To start, add Nexa as a connector, sign in to your Nexa account and press “Allow”.

“What’s on my plate today?”
Meetings, today’s and overdue tasks, clients due for a call and exclusives that are about to expire.
“Find listings for the Cohen project and put together a shortlist”
Listings matching the project’s criteria and a draft shortlist. Nothing goes to the client until you confirm sending.
“What did 4-room apartments in Be’er Sheva sell for last quarter?”
Median price, price per m² and number of deals from Tax Authority data, broken down by rooms.
“Note: David called, wants a viewing on Thursday at 5 pm”
A note on the client’s profile and a calendar meeting; the assistant checks for conflicts and asks permission before saving.
“Prepare a brokerage order form for Yael for the flat on HaRakevet St.”
A document draft in Nexa. It goes out for signature only after you confirm.
“How is the team doing this month?”
For a brokerage owner: deals and monthly goals by agent, who is behind, and the team’s open tasks.
How to connect
No API keys: you sign in with your Nexa account. Agent and brokerage accounts can connect.
Claude
- Press “Connect to Claude” above — the Add connector dialog opens with the name and URL filled in. Or manually: Settings → Connectors → “Add custom connector”, name — Nexa, URL — copy it from above.
- Press “Connect”, sign in to Nexa and press “Allow”.
- In a new chat turn on Nexa in the tools menu and ask: “What’s on my plate today?”
A connector added on claude.ai also appears in Claude Desktop and the mobile app. On Team and Enterprise the organisation owner adds it.
ChatGPT
- Settings → Apps & Connectors → Advanced → turn on Developer mode (on Business — the workspace admin).
- “Create”: name — Nexa, MCP server URL — copy it from above, authentication — OAuth.
- Press “Connect”, sign in to Nexa and press “Allow”. In a chat pick Nexa and ask: “What’s on my plate today?”
Until Nexa appears in the ChatGPT app directory, connecting works in Developer mode and on Business / Enterprise.
Security and control
- Only your data
- The assistant sees exactly what you see in your Nexa workspace and nothing beyond your permissions. Other agents’ data is not available to it.
- Changes need your permission
- Reading happens without prompts. Before each change Claude asks for permission, unless you chose “Always allow” yourself.
- Log and undo
- Every change is recorded in the connection log in Nexa. A note, task, meeting or stage can be undone within 24 hours.
- Nothing reaches a client without you
- Sends to clients, listing publication and invitations are created as drafts and go out only after you confirm in Nexa — or in the chat, if you enabled that right yourself.
- Permissions and disconnecting
- In Nexa: Settings → AI connections. Write and send rights are switched per connection, and you can disconnect at any time.
- What Nexa receives
- Nexa receives only the assistant’s tool requests — not your whole conversation with it. How Claude and ChatGPT store conversations is governed by their own policies.
Limitations
- Only agent and brokerage accounts can connect; client accounts cannot.
- Lists come back short — up to 25 rows. Narrow the request to find what you need.
- There are daily limits on changes and market questions to prevent bulk operations.
- Deal data covers Israel and comes from the Tax Authority register; the latest months are incomplete. This is market analysis, not a licensed appraisal (שמאות).
- The assistant does not permanently delete clients or listings and does not change billing settings.
Questions
How much does it cost?
The connector is part of Nexa, and Nexa has a free plan. Access to connectors in Claude and ChatGPT depends on your plan with them.

No. Only what is available to you in your workspace. A brokerage owner or manager sees brokerage data within their permissions.

In Nexa: Settings → AI connections → “Disconnect”. Access is closed immediately. You can also remove the connector in Claude or ChatGPT settings.
