Cypher and MCP

Reproduce the resolution chain directly against graph.whisper.security:

MATCH (h:HOSTNAME {name: "docker.com"})-[:RESOLVES_TO]->(ip:IPV4)
      -[:ANNOUNCED_BY]->(ap:ANNOUNCED_PREFIX)
      -[:ROUTES]->(asn:ASN)-[:HAS_NAME]->(n:ASN_NAME)
RETURN ip.name AS ip, ap.name AS prefix, asn.name AS asn, n.name AS operator
LIMIT 20
