"Top 100 MCP Servers Ranked by Weekly Downloads" matching MCP servers:

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.

Infrastructure access broker for AI agents — SSH & Kubernetes. Per-operation ephemeral credentials minted by a separate signer; the model never touches one. MCP stdio / HTTP+OIDC.

The official remote Model Context Protocol (MCP) server for Muumuu Domain — a domain registration service operated by GMO Pepabo, Inc. Search and register domains, manage owned domains and contracts, and configure DNS records — all through natural language conversations with AI assistants.

Enables LLMs to configure Tencent Cloud resources such as DNSPod DNS records and CVM/Lighthouse security group rules by controlling a locally logged-in Edge browser over CDP, leveraging existing login state without needing API keys or credentials.

Enables Claude and other MCP clients to discover and call 425 Hitachi VSP One Block REST API operations for storage management, with read-only safety by default, session handling, asynchronous jobs, downloads/uploads, and configurable direct tools.

MCP server that exposes Avangenio's service status by fetching and parsing status.avangenio.com/data.txt into normalized JSON.

Read-only access to a local Hiberden backup catalog: list projects, archives, tapes, and jobs, check 3-2-1 coverage, and verify a stored copy by reading it back and re-hashing it. Runs against the catalog on your own machine, so nothing leaves it.

Diagnoses a domain's email authentication — SPF, DMARC, DKIM, MX, blacklists and domain or SSL expiry - and returns copy-paste fix records generated by a validating engine, never a language model. The MCP server is hosted remotely; this repository carries the plugin manifest, connector config and bundled skill.

Enables agents to discover, rank, live-test, and cache free HTTP/HTTPS/SOCKS proxies, optionally filtered by country or protocol, returning the fastest working proxy and backups for routing requests through specific regions.

Enables natural language orchestration of multi-vendor network infrastructure by combining NAPALM for structured data retrieval and Netmiko for CLI execution via Nornir.

Answers "what is this IP" by matching addresses against a synced local copy of Azure service tags and live reverse DNS lookups, including the reverse direction of listing every CIDR prefix for a given service-tag name. Every answer is honestly labeled with the source that produced it, a sync timestamp, and an explicit null/status when a source didn't resolve, so nothing is fabricated.

Checks email deliverability: audits a domain's SPF (including the 10-lookup limit), DKIM, DMARC and MX records with ranked fixes, checks a sending IP's reverse DNS and blocklist listings, and tests email headers against Gmail and Yahoo bulk sender requirements.

Enables Claude to run safe, read-only diagnostics against servers and websites — certificate chains and expiry, HTTP status/redirects/security headers, DNS records, email authentication (SPF, DKIM, DMARC, MTA-STS, TLS-RPT) and sitemaps. Every check returns severity-tagged findings with concrete fixes, plus a 0-100 score and A-F grade, without any ability to modify the target.

Enables AI assistants to perform network diagnostics by exposing ping and traceroute as callable MCP tools, allowing them to check host connectivity and trace network paths.

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 diagnosing web hosting and server issues by running live HTTP, SSL, DNS, and security-header checks alongside a searchable troubleshooting knowledge base.

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.

Domain security reconnaissance for AI agents — 13 tools (DNS+DNSSEC, SSL/TLS, HTTP security headers, SPF/DKIM/DMARC email auth, port scan, ASN, RDAP/WHOIS) plus a one-shot security_scan returning a 0–100 Health Score (A–F). Free, no API key.

An MCP server that enables AI assistants to diagnose network and service problems by walking a structured funnel of cURL timing metrics, identifying which hop is at fault, and providing targeted recommendations.

Enables AI assistants to generate brandable business names and verify each candidate across TLDs with real registry lookups, ranking results by availability. Also checks individual or bulk domains for registration status, expiry, DNS, email and TLS details via RDAP, WHOIS and DNS probes.

A local MCP server for safely managing Control D DNS by conversation, enabling inspection of profiles and endpoints, diagnosing blocked queries, and creating/deleting rules with confirmation and read-back checks.

Official Porkbun MCP server, maintained by Porkbun. Check availability and pricing, register, renew and transfer domains, and manage DNS, nameservers, URL forwarding, glue, DNSSEC, DNS restore points, static hosting, webhooks and Cloudflare-connected domains. Hosted at mcp.porkbun.com/mcp with Porkbun sign-in (no API key), or run locally with npx @porkbunllc/mcp-server. Docs: porkbun.com/mcp

Lets Claude or any MCP client inspect a TP-Link Deco mesh locally — nodes, backhaul, clients, WAN, firmware — and carefully change settings with graded, read-back-verified writes, secrets redacted by default and an optional read-only mode. No cloud or app involved.

Thin MCP server for Cisco CML2 that exposes the live OpenAPI specification and a generic API call tool, enabling models to interact with CML2 by reading the spec first.

Exposes the full Contabo API (all 157 operations) to OpenAI-compatible agents, enabling management of instances, snapshots, images, object storage, private networks, firewalls, DNS, domains, VIPs, secrets, tags, users, and audits. Operates read-only by default, with POST/PATCH/PUT/DELETE operations unlocked via an environment flag, while handling OAuth2 authentication and token caching automatically.

Provides a secure, job-oriented MCP connector for NetBox device lookup, enabling retrieval of device identity, status, site, role, and primary IP by name or ID without write access or bulk enumeration.

Enables read-only troubleshooting of JUNOS devices by running show commands over NETCONF, with dynamic device discovery from an orchestrator.

Provides MCP tools to query, compare, and analyze network device configurations managed by Oxidized, such as listing devices, viewing backup status, and generating diffs between configuration versions.

This MCP server helps debug legacy devices behind proxies in OT environments by analyzing web interfaces and generating custom rewrite rules to fix proxy-related issues.

Provides AI-aware failover for Mihomo proxy on macOS by validating real OpenAI paths and switching proxy groups after verified hard failures. It offers a local stdio MCP server for diagnostics, status, and safe management of the AI proxy group.
