Popular MCP Servers

Local-first MCP server that lets AI agents design Cisco-style networks and generate L1/L2/L3 topology diagrams, device tables, and AI-ready context files.

Official HostTracker MCP server: run uptime, SSL, DNS, blacklist and page-speed checks from 300+ global locations, and manage monitors, alerts, incidents and status pages. The repo packages the hosted endpoint as a stdio bridge (Dockerfile).

Provides 28 tools for mobile proxies, non-VoIP SMS verifications, dedicated numbers, and global eSIMs, enabling AI agents to perform phone-related tasks.

Self-hostable MCP server for WhisperGraph — a graph of 7.39B nodes / 39B edges mapping DNS, BGP, GeoIP, WHOIS, and threat intelligence. Six read-only tools (Cypher query + schema introspection + threat assessment), six resources, eight investigation prompts. stdio and Streamable HTTP transports.

MCP server that gives Claude and other agents direct control over mobile proxies, enabling proxy management and rotation tasks.

Visual network topology editor with AI agent integration via MCP. One-click SSH + web-service access from any node, nmap/CSV import, smart auto-layout, multi-sheet, local-first. Open-source successor to netViz (CA Technologies 1990-2012)

MCP server for deploying and managing Erebrus decentralized VPN nodes, API keys, and file uploads.

MCP server for Openprovider.com that enables domain management actions such as checking availability, registering domains, listing domains, and managing contacts through natural language.

Enables AI assistants to perform WHOIS, DNS, SSL, and domain availability lookups via the WhoisJSON API.

A read-only MCP server for Akamai Cloud (Linode) that lets users ask plain-language questions about their account, including inventory, pricing, GPU availability, and account limits.

Enables secure, governed interaction with DMTF Redfish-compliant BMCs (iDRAC, iLO, etc.) via MCP, with read-only default and write operations gated behind explicit write-mode elevation and dry-run confirmations.

A Model Context Protocol (MCP) server that provides comprehensive WHOIS lookup capabilities using the IP2WHOIS API. This server allows AI agents to query domain registration details, including expiry dates, registrar information, and registrant data.

Six-layer website monitoring (uptime, performance, SSL, DNS, visual regression, content change) from Claude, Cline, and Cursor. Free tools (DNS lookup, SSL check, speed test, website checker) work without an account; monitor, incident, alert, and status-page tools use a personal API key.

Read-only MCP server for NetBox that enables LLMs to query NetBox objects (devices, IPAM, etc.) and change logs through natural language, with field filtering for token optimization.

Enables AI assistants to query, create, update, and propose changes to Infrahub infrastructure data through the Model Context Protocol, with branch isolation and human approval for changes.

Enables management of 4G/5G mobile proxies from Coronium.io, allowing users to list, rotate, replace, set rotation intervals, buy, renew, and manage subscriptions directly from MCP-compatible AI tools.

Bridges LLMs with Uyuni infrastructure management, enabling natural language system administration such as inspecting systems, managing updates, and scheduling actions.

MCP server that parses 3GPP .docx specifications into structured sections with full-text search, letting LLMs browse, search, and follow cross-references without a vector database.

Enables AI assistants to manage VPS servers, domains, DNS records, and SSH keys through the VPS.org API via natural language.

Uptime monitoring for websites, APIs, SSL certificates, domain expiry, ping and TCP/UDP ports. 15 tools to list, create, pause and delete monitors, pull incident timelines with error codes, and read hourly or daily uptime and response-time statistics.
