"Understanding Prompts or Prompt Engineering" matching MCP servers:

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 an LLM to read and write NetBox data through its REST API, supporting listing endpoints, inspecting schemas, and creating, updating, or deleting objects.

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.

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

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.

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.

A read-only MCP server that lets an AI agent inspect a ROS2 graph, its underlying DDS participants, readers, writers and QoS mismatches, and recorded bag files, with twelve typed tools that behave the same against a live robot or built-in mock fixtures. It has no write path at all, so it can never publish to the bus or command a robot.

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 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 managing GoDaddy domains through MCP, including domain listing, DNS record administration, availability and pricing checks, and domain registration or renewal from any MCP client.

Enables AI agents to query Oracle WebLogic Server runtime state, health, and JVM metrics through the REST management API, and to start, shut down, or force-shut-down servers via Node Manager, all under a least-privilege account with allowlisting, read-only mode, and JSON audit logging for every call.

A modular MCP server for analyzing PCAP files using protocol-specific analysis tools, enabling LLMs to read and analyze network packet captures from local paths or remote URLs.

Enables MCP-speaking agents to claim and manage free subdomains under makes.fyi or agentdomains.co, including DNS records, HTTPS, URL forwarding, reverse proxying, and account management.

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

Enables Claude Desktop to control serial-port devices like network craft ports, radios, rotators, and microcontrollers by sending commands and reading responses until a prompt or available output.

Enables coding agents to perform network diagnostics and lookups, including subnet calculations, port and MAC vendor information, DNS and blocklist checks, TLS certificate inspection, and public IP discovery, all without needing an account or sending telemetry.

Provides read-only network engineering analysis by parsing configs and logs to explain config changes, check CIS/PCI compliance, diagnose 802.1X issues, find embedded certificates, infer topology, and assess proposed changes before pushing them.

MCP server for email deliverability: validate SPF/DKIM/DMARC/BIMI, check blacklists, test SMTP/IMAP, look up DNS, and generate ready-to-deploy records for any major email provider. Ships with two one-click prompts (audit-deliverability, setup-dns). Public, no auth.

Self-hosted webhook relay and tunnel with Noise NK encryption. Inspect requests, replay webhooks, trace AI pipelines, connect/disconnect tunnels — 13 MCP tools. No tokens or passwords needed.

Enables control of GNS3 network lab automation, including projects, nodes, consoles, and SSH, through Claude Desktop or any MCP-compatible client.
