API & MCP Analysis
For AI-native operators choosing between Hunter.io and LeadLeap, the decision comes down to API accessibility and how easily your agent can interface with each tool.
Hunter.io has the edge here with an official MCP server, letting you connect it directly to Claude or Cursor. LeadLeap requires a REST API integration, which means your agent needs the API docs to build the connection.
"Claude, use Hunter API to find the professional email for the CEO of Stripe."
"Claude, use LeadLeap to find all Series A SaaS companies in fintech that recently posted job openings for VP of Sales."
