"Categorizing messages such as emails or system logs" matching MCP servers:

Enables AI agents to manage VPN infrastructure through provisioning, lifecycle control, traffic routing, and health monitoring.

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.

OPNsense firewall operations via API & mcp. Query ARP, DHCP, firewall rules, logs, interfaces, system status, and packet capture via STDIO or SSE.

Enables MCP clients to query homelab infrastructure such as Proxmox VE, NetBox, systemd services, Grafana, InfluxDB, AdGuard Home, ping logs, and configured HTTP JSON endpoints through read-only tools.

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.

A read-only MCP server that enables Claude to audit Firewalla network security configurations and monitor network activity. It provides tools to inspect devices, rules, alarms, and traffic flows without making any changes to the Firewalla system.

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 interaction with OPNsense firewalls through MCP tools for managing firewall rules, interfaces, DHCP leases, and system monitoring.

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 AI apps to inspect and manage a NextDNS account in plain language — profiles, analytics, query logs, blocklists, security and parental control settings — with every change saved and reversible via undo. It runs self-hosted on your own computer or server, keeps per-profile read/write/hidden permissions, and requires double confirmation for deletions or overwrites.

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.

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.

Enables looking up registration details for domains, URLs, or email addresses, returning registrar, creation and expiry dates, domain age, status codes, nameservers, DNSSEC, and registrant organization and country per domain. Queries registries directly via RDAP or WHOIS with no API key, running on Apify.

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

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.

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 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.

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 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.

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 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 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.

Enables AI agents to perform real-time email verification, bulk address checks, and domain deliverability diagnostics such as MX, SPF, DKIM, and DMARC through MCP tools.

MCP server that lets AI agents use the Online Cyber Tools catalogue as a set of native MCP tools.
