WHOIS
Provides network information lookup through WHOIS and RIR database queries across RIPE NCC and ARIN regions, enabling contact card lookups, AS-SET expansion, route object validation, and BGP security analysis with TTL-based caching and async processing.
About
This MCP server provides network information lookup tools through WHOIS and RIR (Regional Internet Registry) database queries, supporting both RIPE NCC (Europe/Middle East/Central Asia) and ARIN (North America) regions with configurable RIR support. Built with Python using FastMCP, httpx, and aiohttp, it offers tools for raw WHOIS queries, contact card lookups for abuse/NOC/admin contacts, AS-SET expansion into concrete ASN lists with configurable recursion depth, and route object validation for BGP security workflows. The implementation includes TTL-based caching, async processing with proper timeout handling, and modular architecture separating RIR-specific functionality, making it valuable for network administrators conducting incident response, security researchers validating route objects, and network engineers analyzing AS-SET hierarchies and contact information across multiple RIR databases.
