Summarize this week’s conversations and tell me which customers I should follow up with.

Nexlab Business

I found 12 important conversations. I have separated out leads, common questions and cases that need a human reply.

Next step

I can prepare a campaign, update a page, or leave notes on the contacts so the team can pick it up.

01 — How it connects

Setup takes a few minutes. The technical part stays hidden.

You only need to copy the connection URL, add it in your AI client, and authorize access with your Nexlab account.

01

Copy the connection URL

This is the address of the Nexlab Business MCP server. It is the same for every client:

https://business.nexlab.dev/mcp
02

Add it in your AI client

In Claude, ChatGPT, Cursor or your terminal, add a custom connector or MCP server with that URL. The exact steps for each client are below.

03

Authorize access

Nexlab will ask you to sign in and choose which business that connector can use.

04

Start with a real task

Try something simple: summarize conversations, review reports, or prepare content.

02 — Connect your client

Choose your client. The exact steps for each one.

03 — What it is for

Your AI stops answering in the abstract. Now it understands your business.

01

Serve customers better

Summarize conversations, spot hot leads and find common questions without going through chat after chat.

02

Update content

Ask for changes to pages, products, blog or messages, and review the result before publishing it.

03

Understand results

Ask for reports in plain words: what changed, what is going well and what you should do next.

04 — Examples

Things you can ask it for.

  • Summarize yesterday’s conversations and tell me who needs following up.
  • Create a promotion for the customers interested in booking.
  • Find free slots this week and draft a reply for the customer.
  • Update the main text on my page with a clearer version.
  • Show me what changed in sales, messages and expenses since last week.
05 — Connection URL

Use this URL when your AI client asks for the MCP server.

After you authorize access, your assistant will be able to work with the information for the business you selected in Nexlab Business.
