Wraps the Hunter.io API for email discovery and verification directly into your MCP client. Useful when you need to find professional email addresses associated with a domain, verify if an email exists, or enrich contact data during research and outreach workflows. Hosted through Pipeworx's gateway, so you can connect via a simple HTTP URL without running a local server. The source doesn't list specific tools, but Hunter.io typically offers domain search, email finder, and verification endpoints. You can either call tools directly or use the ask_pipeworx interface to query in natural language. If you're building lead lists, validating contacts, or doing any kind of B2B prospecting from Claude, this gives you programmatic access to Hunter's database without leaving your agent environment.
