Leadmaps for ChatGPT — connect a European business database

ChatGPT supports MCP connectors on paid plans: point it at mcp.leadmaps.io with your API key and it gains six tools for counting, searching and exporting local businesses. On plans without connectors, the REST API works from Actions.

Setup

Create your API key at app.leadmaps.io/keys.
In ChatGPT, open Settings → Connectors → Add custom connector (MCP).
URL: https://mcp.leadmaps.io/mcp — header Authorization: Bearer lm_live_xxx.
Start with a free count: “count plumbers in Nantes rated 4.5+”.

    }
  }
}

3 copy-paste prompts

Count plumbers rated ≥ 4.5 in Nantes, then deliver the top 20 with phone and website.
Find 150 real-estate agencies in Lille rated ≥ 4.4 with a website, export to CSV.
List categories around “food”, then count pizzerias without a website in the Rhône department.

FAQ

Are MCP connectors available on my ChatGPT plan?

Custom MCP connectors require a paid ChatGPT plan. Without connectors, the Leadmaps REST API works through Actions (OpenAPI schema at docs.leadmaps.io).

Which API key should I use in ChatGPT?

A free lm_test_ key (sandbox of ~5,000 real listings, 0 credits) to try things out, an lm_live_ key in production — both created and revoked at app.leadmaps.io/keys.

What does a ChatGPT-initiated request cost?

Counting and facets are free; 1 credit = 1 delivered listing, and any listing already delivered can be re-delivered for free for 30 days.
