Claude

First-class support in Claude Desktop, Claude Code, and the API.

B2BLeads was built MCP-first with Claude in mind. Add the npm package to Claude Desktop's or Claude Code's config and Claude gets all five tools — search_leads, list_industries, list_saved_lists, get_saved_list, and find_email — as native capabilities in every conversation.

Because it's a local stdio server, Claude Code can also drive it from inside an agentic coding session — e.g. "find 20 roofing companies in Austin and save them to a list" — without you leaving the terminal.

The same server also works over the Claude API/Agent SDK for anyone building their own Claude-powered app that needs live B2B data instead of a static dataset.
