Target key domains directly within Claude Desktop

The `domain_search` tool lets your agent pull verified email lists for any company domain directly into your Claude Desktop chat window. You get immediate access to public contact data without switching tabs to a browser. Before pulling a massive list, use `email_count` to check how many addresses exist for a domain. This prevents your agent from burning your Hunter API credit budget on overly broad queries during a chat session.

Find and verify specific contacts in Claude Desktop

The `email_finder` tool locates the exact email address of a prospect using their name and company domain name directly from your Claude Desktop prompt. Your agent processes the raw data instantly, giving you a direct line to decision-makers. To protect your sender reputation from high bounce rates, run `email_verifier` on the found address before sending any outreach. Claude Desktop displays the deliverability status in the chat, keeping your domain off spam blocklists.

Manage your outreach lists using this MCP Server

The `list_leads` tool pulls your saved prospects directly into Claude Desktop so you can organize your sales pipeline. Your agent parses the lead details, allowing you to filter contacts by industry or job title on the fly. You can also run `list_campaigns` and `list_recipients` to monitor active outreach sequences without opening the Hunter dashboard. This turns Claude Desktop into a lightweight, local control center for your email campaigns.
