CyberSPF

Overview

CyberSPF is an MCP server that assesses domains, IP addresses, and ASNs to evaluate mail and DNS security, certificates, routing, and provide detailed report cards. It integrates directly into AI assistants as callable tools, letting Claude and other models run security assessments on your behalf.

The server runs locally via the cyberspf-mcp Python package, installed through uvx. You'll need to provide a CYBERSPF_API_KEY environment variable to authenticate with the service. The latest release is v0.2.0.

CyberSPF appears in the Security category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you're the maintainer at cyberspf.com, claim this listing to verify ownership and keep the information accurate.
