"address validation" matching MCP servers:

MAC-address (OUI) vendor lookup and router default-login directory for AI agents, backed by ssid.ai. Identify a device manufacturer from its MAC address, detect randomized/private addresses instead of reporting unknown, or fetch a router's default login IP and admin credentials — every field cited to the manufacturer's own documentation

Enables querying IP address intelligence through the IPinfo API, including geolocation, ASN, and network details, via natural language to MCP clients.

An MCP server for domain intelligence — WHOIS, DNS records, SSL certificate inspection, SPF/DMARC validation, security-header audits, and blacklist/reputation checks, callable by AI agents. Powered by domainintel.app; runs server-side, no local setup.

Model Context Protocol (MCP) server for deep DNS resolution, nameserver propagation, and DNSSEC validation

Enables AI agents to explore licensed IP intelligence databases through four read-only tools: listing the databases an organization is licensed for, inspecting a database's columns, sample rows, row count and build date, fetching published checksums for verifying a local copy, and reviewing recent download attempts. It covers VPN, proxy, hosting, CDN and relay address space data without transferring the multi-gigabyte files themselves.

Check whether a URL is allowed under a network-egress policy before any fetch, with tools for single URL, batch checks, and policy validation.

Enables conversion of Nginx Ingress resources to AWS Gateway API (ALB/NLB) YAML through a conversational interface, with validation and migration reporting.

Enables building Huawei eNSP network topologies and configuring lab devices through console ports, including device creation, wiring, layout, validation, and batch configuration.

An MCP server for network engineering that provides comprehensive tools for BGP analysis, RPKI validation, and DNSSEC-aware DNS queries. It integrates public data sources like RIPE and Cloudflare Radar with local diagnostic tools to give LLMs structured access to real-time and historical network states.

Enables interaction with phpIPAM IP address management (IPAM) system, providing tools to manage IP sections, subnets, addresses, VLANs, and more through natural language.

Comprehensive DNS security toolkit for AI agents: 103 tools across 13 categories including DNSSEC validation, subdomain takeover detection, email security audit, and more, all running locally with no external API calls required.

MCP server for phpIPAM IP address management, enabling subnet, VLAN, VRF, and address operations via natural language.

Enables IPv4 subnet planning and validation, including CIDR prefix calculation, wildcard mask generation, and host position lookup for network engineers.

Domain Name System Security Extensions (DNSSEC) Validation & Cryptographic Auditing MCP Server

Give each local app its own private HTTPS address on your Tailscale network, and control who can reach it, from your AI agent through MCP.

MCP server for network diagnostics providing tools like ping, DNS lookup, port check, traceroute, speed test, Wake-on-LAN, SSL certificate check, and MAC address lookup.

Enables AI clients to call a broad set of Dutch data and validation API endpoints as tools, including address, postcode, IP, DNS, IBAN/VAT, vehicle, and property lookups, with secure API-key handling and automatic tool-list updates.

Gives Claude 8 real-world tools via a single free API key: SSL certificate inspection, WHOIS lookup, email validation (syntax + MX + disposable detection), webpage screenshots, IP geolocation, currency conversion, schema markup generation, and UK business-day calculations. Python, pip install forevertools-mcp, MIT licensed.

Look up any IP address with FindIP: geolocation, network and ASN, and VPN, proxy, Tor and datacenter detection. For websites that use FindIP Shield, list the recent risky visitor events and explain the reasons behind one event.

Enables AI assistants to operate Juniper Junos and SRX network devices over NETCONF and SCP, running operational CLI and PFE commands, inspecting and diffing configuration, validating and committing changes with confirmed auto-rollback, and managing SRX security workflows such as signature-package updates, chassis-cluster health, and read-only policy and address-book inspection.
