PeeringDB MCP — the peering ecosystem database.

OpenCellID MCP — cell tower geolocation database (free with key)

Provides capabilities that let LLM agents perform a range of infrastructure management tasks.

The internet's largest queryable infrastructure graph — 7.39 billion nodes, 39 billion edges, 5.6 million threat-intelligence relationships. Pivot from any IP, domain, or ASN across DNS, BGP, WHOIS, GeoIP, and threat intel in a single Cypher query. Most threat-intel and OSINT APIs are point lookups: you ask about one indicator, you get one record. Investigations don't work that way — you start from one suspicious domain and need to trace its hosting, its sibling domains, its registrar, its email

Live demo of Frisian-MCP, a Django/DRF package that exposes ViewSets as MCP tools through grouped dispatchers — ~1,800 endpoints collapsed into ~16 tools, with DRF permission classes enforced in-process before ORM access. Connect to try the dispatcher pattern against a realistic network-automation surface.

Gives AI agents a public IPv6 identity, hostname, port forwarding, web fetch, team mesh. Free tier.
