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.

Enables AI assistants to manage DNS filtering accounts by blocking or allowing domains, checking policies, reviewing blocked queries, and managing filter categories, schedules, and devices through natural language.

Enables AI assistants to explore a company's external attack surface and its findings through read-only tools that list and filter assets (domains, IPs, ranges, certificates, software) and vulnerabilities with pagination, summaries, evidence, and safe access to additional read-only API endpoints. It also handles rate limits, large-company summaries in the background, and quirks of the Attack Surface Management API so results stay complete and consistent.

Exposes FFraud's fraud-detection tools so assistants can score a website's security, rate any IP for fraud and VPN/proxy/Tor use, and flag disposable emails, throwaway-mailbox domains, and community IP reports. It runs as a remote MCP endpoint or locally over stdio with no API key required.

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.

NexaLayer MCP Server — a Model Context Protocol server that lets AI agents create and manage dynamic and static proxy sessions with budget guardrails.

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.

Official MCP server for the BunkerWeb web application firewall. Manage services, instances, IP bans, configuration, plugins, and scheduler jobs over stdio or streamable HTTP.

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.

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.

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.

Website monitoring for AI assistants. Visual Sentinel catches pages that look broken even when the site is up. DNS, SSL, speed and website checks need no account; monitors, incidents and alerts need an API key (Business and Agency plans).

Provides a security proxy that sits between MCP clients and servers to inspect and filter traffic. Guards MCP sessions against leaked secrets, vulnerable dependencies, misconfigured DNS/TLS, and non-compliant data exposure.

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.

A local stdio MCP server that lets AI clients inspect and control a Lemon-enabled iPhone over the local WebControl API, discovering the device via Bonjour. It exposes tools and resources for VPN toggling, embedded web pages, scheduled JavaScript tasks, captured traffic, logs, files, SQLite queries, DNS hosts, HTTP replay, rewrite scripts and rules, and UI modules.

The network-change verifier for AI agents: validate a BGP or routing change in a real containerlab lab before it reaches production, and get a pass, fail or inconclusive verdict with evidence. Runs on FRR, Nokia SR Linux, SONiC and Arista cEOS.

Read-only MCP server for CometBFT/Cosmos validator operators: checks signing liveness and downtime-jail risk, diagnoses chain halts (who isn't voting), and reports peer topology and upgrade readiness. Keyless and GET-only, with node IPs masked by default.

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.

Enables MCP-compatible clients to list verified free HTTP, SOCKS4, and SOCKS5 proxies, pick top-ranked ones, and summarize the current proxy snapshot through three read-only tools, without forwarding traffic or accepting arbitrary URLs.

A Model Context Protocol server for the AVEQ Surfmeter management API. It exposes typed tools for clients, measurements, anomalies, groups, ISPs, users, keys, capabilities, settings, license usage, and the built-in AI assistant.

Enables AI agents to manage EMQX Cloud through separate Platform and Deployment API connections, covering project and deployment lifecycle, MQTT client, subscription and metric inspection, built-in authentication users and ACL rules, banned lists, retained messages, publishing, and data integration. It is read-only by default, with opt-in flags for write, destructive, and integration operations.

Enables AI assistants to bulk-check hundreds of brainstormed domain names in a single call, reporting which are available, taken, or reserved along with buy links and prices from multiple registrars. It runs locally via DNS, RDAP, and WHOIS lookups, with optional registrar API keys for confirming availability and premium pricing.

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.

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

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).

Read-only help with SSH, tmux and Tailscale setup for running AI agents from an iPhone or iPad.

Read-only MCP server for NodeMaven residential proxies: builds proxy URLs with country, city and ISP targeting and sticky sessions, checks a proxy and reports its exit IP, lists available locations, and shows traffic usage.

Enables AI agents to securely inspect and manage DNS zones, DNS records, DNSSEC settings, and TSIG keys through an authenticated account API.

Lets AI agents and assistants check domains or links for safety before opening them, returning verdicts, risk scores, advice, and DNS resolution details through DNS-over-HTTPS.
