Whisper Graph

Gives Claude direct access to WhisperGraph, a 46 billion node graph database mapping DNS records, IP addresses, ASNs, BGP routes, WHOIS data, and threat intelligence across the entire internet. You can run Cypher queries to trace infrastructure relationships, pivot through domain ownership, check threat scores across 40 feeds, analyze BGP hijacks, or hunt typosquatting domains. Ships with six tools including query execution, label inspection, and threat assessment, plus eight investigation prompt templates for common security workflows. Supports both stdio for local use and a hosted remote server at mcp.whisper.security. Agents can sign up programmatically in two API calls without touching a browser. Useful for incident response, infrastructure forensics, brand protection, or any investigation that needs to map how domains, IPs, and organizations connect across the internet's routing and naming layers.
