Overview

What is Leadenrich Mcp?

Leadenrich Mcp is a waterfall lead enrichment server that implements the Model Context Protocol (MCP). It cascades through Apollo, Clearbit, and Hunter to build the most complete lead profile in a single call, returning merged profiles with per-field attribution. It is designed for AI agents like Claude and Cursor to run enrichment workflows directly.

How to use Leadenrich Mcp?

Install via pip install leadenrich-mcp and start the server with leadenrich-mcp (defaults to http://localhost:8300/mcp). Connect from Claude Desktop by adding the server URL to claude_desktop_config.json, or from Claude Code using claude mcp add leadenrich --transport http http://localhost:8300/mcp. Provider API keys (Apollo, Clearbit, Hunter) are set as environment variables; all are optional.
