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.

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.

An MCP server that exposes WLAN Pi capabilities like device info, Wi-Fi scanning, service management, and VLANs to AI assistants via the wlanpi-core REST API.

Enables any MCP client to look up CVE intelligence — severity summaries, filtered searches, and full per-CVE detail fusing NVD, MITRE-CNA pre-NVD, CISA KEV, EPSS, and GitHub GHSA data — alongside a Shodan-derived internet-exposure footprint showing how many internet-facing services run a version mapping to a given CVE. It is free, keyless, and read-only, and distinguishes verified zeros from unassessed or failed lookups.

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

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

Enables managing Hostkey .ru cloud account resources via natural language, including servers, ordering, power control, OS reinstall, networking, DNS, snapshots, and billing.

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 MCP clients to query proxy sub-accounts, traffic, pricing, and inventory, and to place orders, renew, and modify configurations after user confirmation.

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

Enables AI assistants to view devices on a Portveil account and move, rotate, reconnect, or disconnect them across VPN locations, with verified successful moves.

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.

Uptime monitoring from your AI agent: create and diagnose checks (40 types: HTTP, TCP, DNS, SSL, ICMP, databases, message queues and more), read results and incidents, and manage status pages and maintenance windows. Built into the self-hostable SolidPing server, served over streamable HTTP at /api/v1/mcp.

Reviewed proxy documentation, tested configuration examples and structured error diagnostics for MCP clients.

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.

Enables AI to query live weather, domains, IPs, DNS, SSL, currency rates, and more via the APIFreaks API.

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.

Enables reading nginx configs, managing reverse proxy hosts, and handling SSL certificates via certbot, with read-only tools ready and mutating tools guarded as stubs.

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.
