An unofficial MCP server that connects AI assistants to Akamai APIs, providing tools for edge diagnostics, debugging, and network analysis.

Enables n8n AI agents to manage MikroTik routers via SSH/SSE, providing tools for firewall, DNS, DHCP, WireGuard, interfaces, queues, backup, users, logs, and routes.

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.

Manage a fleet of OPNsense firewalls from an AI agent, inside guardrails it can't drive around. MCP server for central management of OPNsense firewall fleets. 129 tools across devices, config sync, tasks, schedules, templates, backups and remote consoles - destructive actions confirmation-gated, MCP-issued tokens lifetime-bounded, backup and storage secrets excluded from the toolset entirely.

It lets users manage a pfSense firewall conversationally from Claude Desktop, Claude Code, or any MCP client — creating and reordering firewall rules, NAT, VPN tunnels, DNS, DHCP, certificates, and running diagnostics. Every configuration change passes through safety guardrails with confirmation prompts, rate limits, and rollback points.

Exposes Palo Alto Networks Strata Cloud Manager API via MCP, enabling AI assistants to manage addresses, security rules, and incidents through natural language.

Operate packet-radio digipeater nodes from Claude and other MCP clients.

Enables AI agents to invoke tools over a mutually authenticated TLS endpoint, with server-side certificate and identity checks plus fail-closed per-tool authorization through Open Policy Agent.

Enables querying an F5 BIG-IP lab through read-only iControl REST calls, letting Claude inspect system and HA status, virtual servers, pool member health, monitors, and other objects via natural language. All tools are GET-only and paired with a read-only BIG-IP user role so nothing on the device can be changed.

Enables recurring website maintenance checks — domain registration, SSL certificates, uptime, technical SEO and accessibility — across a portfolio of client sites, using publicly available information. Results are returned as structured data and can be sorted by urgency into a client-ready report.

Gives AI agents access to public internet interconnection data, letting them look up which networks connect to each other, at which internet exchanges and facilities they are present, under what peering policy, and who a given IP range or AS number is registered to. Responses are compact, sourced and aged, and it distinguishes missing records from genuinely absent networks rather than guessing.

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.

A Model Context Protocol (MCP) server that exposes the full WhoisFreaks API suite as AI-callable tools. Works with Claude Desktop, Cursor, Windsurf, VS Code, Continue, Zed, and any other MCP-compatible AI client.

Enables an LLM agent to investigate a Kong Gateway through fourteen read-only, schema-validated tools and a deterministic diagnostic engine, so it can trace routes, services, plugins and upstream health and explain faults such as why authentication is failing on a path. Every fact comes from the gateway itself, and the model only selects tools and writes the evidence-backed explanation.

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

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.

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

A read-only MCP server for the Logitech Sync Cloud API, providing tools to inspect rooms, desks, devices, health, occupancy, coverage, environmental readings, and network information.

Provides read-only network diagnostics for a target host, including DNS, TLS, HTTP, and registry data.

Exposes network-monitoring tools (query metrics, analyze windows, compare, logs, status, runbooks, speed tests) as an MCP server for agentic workflows. Designed with evaluation suites, cost-aware model routing, and semantic tool retrieval.

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

Enables AI agents to query and manage Cisco Crosswork Network Controller resources such as devices, credential profiles, providers, topology, tags, alarms, users, applications, and inventory jobs, with optional write operations for creating, updating, and deleting devices, credential profiles, and providers.

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 AI coding assistants to access the internet through VPN exit nodes to bypass geo-restrictions and avoid rate limits. It allows users to route HTTP requests through various global regions and manage VPN connections directly within MCP-compatible clients.

Checks and fixes a domain's email authentication (SPF, DKIM, DMARC), DNS health, propagation, blacklists and domain/SSL expiry, returning copy-paste fix records from a validating engine, never a model guess. Local stdio server (npx -y @dnsdoctor/mcp) with the same 27 tools as the hosted https://dnsdoctor.dev/mcp.

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.

Enables MCP clients to query a Twingate network in read-only fashion for users, groups, resources, remote networks, connectors, devices, and access relationships.

A Model Context Protocol server for performing WHOIS domain lookups directly via TCP port 43, supporting over 877 TLDs and parsing for 169 country-code TLDs.

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 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 assistants to check domain availability in real-time during brand naming conversations, using DNS and WHOIS queries to suggest available domains for brainstormed names.
