Overview

What is sec-mcp?

sec-mcp is a Python toolkit providing security checks for domains, URLs, IP addresses, and more against multiple blacklist feeds. It can be integrated into Python applications, used via terminal CLI, or run as an MCP server to enrich LLM context with real-time threat insights. Developed by Montimage.

How to use sec-mcp?

Install via pip install sec-mcp, then use the CLI commands (sec-mcp status, sec-mcp update, sec-mcp check, sec-mcp batch) or import the SecMCP class in Python. To use it as an MCP server, configure your MCP client (e.g., Claude, Windsurf, Cursor) to run python -m sec_mcp.start_server from a virtual environment with the absolute path to the Python executable.

Key features of sec-mcp

  • Checks domains, URLs, IP addresses against multiple blacklist feeds
  • On-demand updates from OpenPhish, PhishStats, URLhaus and custom sources
  • Thread-safe SQLite storage with in-memory caching for fast lookups
  • Python API via the SecMCP class
  • Click-based CLI for interactive single or batch scans
  • Built-in MCP server support for LLM/AI integrations over JSON/STDIO

Use cases of sec-mcp

  • Real-time security checks for domains, URLs, or IPs in LLM workflows
  • Batch scanning of multiple indicators from a file
