What is CUFinder MCP

CUFinder MCP lets AI agents securely access the CUFinder API and enrich their answers with real B2B data. MCP (Model Context Protocol) is a standard that allows AI tools to connect with third-party APIs in a secure, consistent way.

In our case, it connects AI tools with CUFinder, enabling things like finding verified business emails, enriching company profiles, discovering decision-makers, and accessing real-time B2B intelligence directly within your AI workflows, like this:

With the CUFinder MCP server, your AI assistant can tap into over 1 billion enriched people profiles and 85 million company records—refreshed daily—without leaving your conversation. Whether you're prospecting for leads, validating contact information, or building targeted outreach lists, the MCP integration brings CUFinder directly to your AI environment.
