LayerCall is a Model Context Protocol (MCP) server: Score an IP, email, phone, domain or device for fraud in one call, with the signals behind it. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://www.layercall.com/api/mcp and you're connected, with nothing to install locally. The current release is v1.0.0, published under the MIT license, with source at LayerCall/layercall-sdk on GitHub.
You'll find LayerCall in the Communication category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
