Leadsapp is a Model Context Protocol (MCP) server: Search 136M+ US/CA B2B contacts free, verify emails free, get compliance verdicts. Pay per reveal. In practice that means any MCP-compatible AI assistant can call Leadsapp's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://leadsapp.com/api/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
Leadsapp is listed under Security on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
