"How to use Google Search" matching MCP servers:

Routes web requests from AI tools through Tor for anonymized fetching, with selective per-URL routing to bypass Tor-blocking sites.

Enables agents to run SEO and AI-search readiness audits (llms.txt, crawler access, sitemaps, structured data, redirects, indexability, and more), look up startup revenue listings and leaderboards, and check a domain's SPF, DKIM, DMARC, and MX records with concrete fixes. Runs locally over stdio with no account or API key, and frames all third-party responses as untrusted data.

Enables LLM agents to read 3x-ui panel data and perform full CRUD operations on inbounds and clients.

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.

See which process holds a local port and who started it, find free ports, wait for services, and stop a dev server safely. Fixes "port already in use" (EADDRINUSE) for AI coding assistants. Never stops system processes; Docker and WSL ports get the right stop command. Run with: npx -y portcheck-cli mcp

An MCP server for domain name availability checking, WHOIS lookups, and domain suggestions — no API key required.

An MCP server that gives an AI agent safe, high-level control over Namecheap domains – availability checks, registration, DNS, email forwarding, transfers, WhoisGuard privacy, and account balance via Namecheap's XML API. Designed for safe LLM interaction with built-in confirmation gates and read-modify-write DNS operations.

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.

Enables MCP clients to search, describe, and call roughly 180 undocumented UniFi OS/Network console API operations from a bundled OpenAPI spec, plus curated reads and typed configuration changes. Writes are off by default, require per-entity enablement, and use previews, verification, and rollback safeguards.

Provides DNS lookup and email authentication diagnostic tools (SPF, DKIM, DMARC, MX, etc.) for use with MCP-compatible clients. Enables natural language queries to check DNS records and email health.

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.

Enables AI agents to run privacy-first network diagnostics (egress IP, proxies, DNS, port checks, security-header audits), handle authentication primitives like TOTP and disposable inboxes, and use developer utilities such as URL-to-markdown reading, webhook inspection, hashing, file/paste sharing, and read-only EVM RPC calls. All tools are free, require no API keys, and operate under a zero-log policy with automatic expiry.

Enables AI agents to manage a UGREEN NAS through the official unc CLI, covering files, search, storage health, Docker containers and Compose projects, downloads, apps, users, network and performance monitoring. Access is gated by read/write/admin tiers, two-step dry-run confirmation for destructive actions, and configurable path allowlists.

A Model Context Protocol (MCP) server for the RIPE Atlas network measurement platform. Enables AI assistants to create network measurements, retrieve results, search probes, and manage credits.

Analyzes Telerik Fiddler SAZ session archives, enabling AI assistants to inspect, search, and filter HTTP sessions, plus performance and security auditing.

Use the MCP servers on your computer from a cloud AI agent: one authenticated Streamable HTTP endpoint, an outbound WebSocket from your computer (no inbound port), and stdio and HTTP servers aggregated under aliases with per-server tool allowlists.

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.

An MCP server exposing 72 tools across 26 homelab services, enabling LLMs to monitor and manage infrastructure, media, storage, and networking with a single endpoint.

Connect your agent to a live, P2P mesh of other agents and consumable mesh services.

Provides search and detail tools for YANG paths across network vendor models (Nokia, Cisco, Arista), enabling models to find correct gNMI paths without guessing. The server is offline and does not connect to any devices.

Enables an agent to administer a Linux host (with first-class Arch support) over SSH through 109 typed tools covering system state, systemd, journal, packages, network, disks, hardware, boot, sessions, users and security, all returning compact JSON. Reads are the default, while mutations require write mode plus a single-use confirmation token, with optional sudo for root-level operations.

A minimal MCP server for Shodan, enabling infrastructure reconnaissance through tools like host lookup, search, CVE lookup, and DNS queries.

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 AI agents to perform passive reconnaissance, vulnerability intelligence, DNS analysis, and device search using Shodan's database of internet-connected devices, all from within your IDE.

Provides tools to classify, test, and expand IPv4/IPv6 addresses using Node's built-in net module.

Enables AI agents and automation pipelines to enrich company domains, audit AI-search readiness, convert web pages to clean Markdown, inspect DNS/DMARC security, and batch-process up to 25 domains per request.

Enables agents to search and call the full OPNsense core and plugin API, perform model-validated CRUD and settings operations, and use curated firewall, service, and network tools with optional auto-revert writes.

Provides MCP servers for VPN control (NordVPN) and torrent lifecycle management via Jackett search and qBittorrent operations, plus a unified CLI.

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 read and manage NetBox network infrastructure data via MCP. Supports querying all object types, search, changelogs, GraphQL, IP/prefix/VLAN allocation, cable tracing, config rendering, and write operations with safety modes.

A hosted MCP server that enables AI agents to interact with the Starlink Enterprise API using service accounts, with transparent OAuth token management and 55 auto-generated tools.

Gives AI agents ten website and domain research tools, including full domain reports, readable page extraction, DNS lookups, feed and sitemap parsing, link and metadata extraction, site checks, and redirect tracing. Calls are paid per use in USDC on Base via x402 from a configured wallet, so no account, API key, or subscription is required.

AgentDomain MCP allows AI agents to register, buy, and manage internet domains via the Model Context Protocol. Features include domain search, availability check, purchase, DNS record management, and wallet operations.

Provides access to Shodan's IoT search engine API for device search, host intelligence, exploit database, network scanning, and security analysis through natural language.

MCP server that enables AI agents to search domain, IP, port, service, title, ICP, server header, and component assets via the SCANDOMAIN API using Quake-style DSL queries.

infomaniak-mcp-agent lets Claude (or any MCP client) drive a real Infomaniak account end-to-end through 54 tools — web hosting, mail, kDrive, domains, DNS, DNSSEC, FTP/SSH users, AI catalogue and more. Every destructive operation goes through a strict two-phase commit (plan + single-use confirmation token) so the agent can never silently mutate your account. Open Source
