"Tools and Methods for Performing OSINT on an IP or Domain" matching MCP servers:

MCP server for live IP and domain reputation checks via DNS lookups, providing abuse scores and network type without requiring an API key.

Enables domain investors, webmasters, and autonomous agents to perform comprehensive domain audits including brand scoring, TLD tier analysis, and DNS connectivity checks, and to generate strategic brand suffixes and industry compound variations for portfolio expansion.

Provides tools to classify, test, and expand IPv4/IPv6 addresses using Node's built-in net module.

An MCP server for domain name availability checking, WHOIS lookups, and domain suggestions — no API key required.

Answers "what is this IP" by matching addresses against a synced local copy of Azure service tags and live reverse DNS lookups, including the reverse direction of listing every CIDR prefix for a given service-tag name. Every answer is honestly labeled with the source that produced it, a sync timestamp, and an explicit null/status when a source didn't resolve, so nothing is fabricated.
