Getting started
Connect your agent
Using Breaknorm from Claude, ChatGPT, Claude Code or Cursor — the short version.
Breaknorm is a hosted MCP server. Any AI client that speaks MCP can search companies, size a market, find lookalikes, keep your customers out of the results, export full lists and find or verify e-mail addresses — inside the conversation. Nothing to install.
The short version
The server URL is:
https://mcp.breaknorm.co/mcp- Claude (web and Desktop), ChatGPT — add it as a custom connector. A browser window opens on app.breaknorm.co: sign in, pick the organization, click Allow. No key to paste.
- Claude Code, Cursor, your own code — create an API key in the dashboard (API keys) and send it as
Authorization: Bearer bnk_live_…. Claude Code can also use the browser sign-in instead.
Step-by-step for every client is in the connect guide.
Did it work?
Ask something that needs real data:
How many industrial pump manufacturers are there in Germany? Break it down by company size.
You should get a number and a breakdown. If you get a hedge or a web search instead, the connector is not active — see my agent isn’t connecting.
What your agent can do
| Ask for | The agent uses |
|---|---|
| “How many … are there?” | count_companies |
| “Find …” | search_companies |
| “More like these three customers” | find_similar |
| “…whose website mentions ATEX” | search_companies with site_text |
| “Read their about page” | get_company_pages, get_page |
| “Split them into groups I can write to differently” | segment_companies |
| “Never show me our existing customers” (per client, for agencies) | create_list with always exclude |
| “Give me the whole list as a CSV” | start_export |
| “Find Anna Schmidt’s e-mail at acme.de” / “Is this address real?” | find_email, verify_email |
| “How much do I have left?” | get_usage |
It cannot search people yet — people search is on its way (see people and contact data).
Your agent sees what every tool costs and how much of your allowance is left (get_usage), so it can
size a segment with a free count before it exports anything.
Keeping it under control
- Ask for the count first. It is quick and tells the agent whether it is looking at 300 companies or 300,000 before it pulls anything.
- Say when not to spend. “Don’t export yet, show me the top 20” works.
- Revoke per client. Connected apps in the dashboard lists every app you approved; API keys lists every key. Revoking one leaves the others alone, and takes effect immediately.
