Overview

AI-generated overview

Lets an assistant find and verify B2B work email addresses and enrich contact records through a hosted remote endpoint.

What it does
LeadMagic is a remote MCP server for B2B contact data. According to its registry description, it finds and verifies work email addresses and enriches contacts, with live SMTP verification of addresses. No tool list is published in the manifest, so the exact tool names and parameters are not documented here.
When to use it
Worth considering when an assistant needs to look up or validate business email addresses or add detail to contact records during sales, recruiting, or outreach research. It is less relevant if you only work with personal email or already have verified contact data.
Requirements
It runs as a remote streamable HTTP endpoint at mcp.leadmagic.io, so no local runtime or package install is needed. The manifest declares no authentication, environment variables, or headers, but a hosted commercial data service of this kind normally requires an account or API credential; confirm the current access requirements with the provider before relying on it.
Before you install
The server sends the contact details you query to a third-party service, so consider whether that data may leave your environment. It is a commercial B2B data product, so usage may be metered or paid; check pricing and quotas. Because no authentication is declared in the manifest, verify how access is actually controlled before connecting it to any assistant that handles sensitive data.
