An MCP server that lets Claude monitor and manage a TrueNAS box in plain English. It is deliberately read-only, providing tools to check alerts, storage pools, snapshots, services, and more.

Enables AI agents to classify IP addresses through the VPNDetection API with read-only tools that detect VPNs, residential and datacenter proxies, Tor nodes, relays, hosting providers and CDNs, in single or bulk lookups of up to 100 addresses. It also exposes which datasets an organisation is licensed for, along with their metadata and published checksums.

Provides read-only access to UniFi Network consoles for sites, devices, clients, vouchers, networks, Wi-Fi, and firewall configuration, with optional opt-in tools for controlled write operations and legacy controller support.

Enables AI assistants to check domain availability in real-time during brand naming conversations, using DNS and WHOIS queries to suggest available domains for brainstormed names.

MCP server that lets AI agents use the Online Cyber Tools catalogue as a set of native MCP tools.

Official Porkbun MCP server, maintained by Porkbun. Check availability and pricing, register, renew and transfer domains, and manage DNS, nameservers, URL forwarding, glue, DNSSEC, DNS restore points, static hosting, webhooks and Cloudflare-connected domains.
