ASN Lookup

IR Toolshed MCP Server provides network analysis tools for security professionals, enabling AI models like Claude to perform lookups and analyses during security investigations. The server currently implements an ASN lookup tool that returns information about IP addresses including AS number and organization name, using the whois.cymru.com service. Future plans include adding DNS lookups, WHOIS record retrieval, IP geolocation, and other network analysis capabilities to create a general-purpose service for network incident responders.
