"Building voice agents and controlling SIP phones" matching MCP servers:

Measure the network path quality to a voice/VoIP destination and get an estimated MOS (ITU-T G.107 E-model) plus live RTT, jitter, and packet loss. Agent-native: REST + MCP, free tier then pay-per-call via x402.

A Docker-based MCP server exposing a curated set of Kali Linux security tools for authorized, hands-on network scanning on private ranges, with enforced trustworthiness and honest output.

Enables AI agents to access curated SIP/VoIP documentation, troubleshoot traces, and analyze telecom configurations with 20+ read-only tools.

MCP server that gives Claude and other agents direct control over mobile proxies, enabling proxy management and rotation tasks.

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.

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

Enables AI agents to perform compensating-control lifecycle operations on Check Point firewalls, including adding access rules, publishing sessions, and installing policies.

MCP server for controlling PNETLab v6 network labs via natural language, enabling topology creation, node management, config push, console interaction, and link fault injection.

MCP server for monitoring and controlling WiFi routers (OpenWrt) via SSH, enabling device listing, status checks, WiFi configuration, rebooting, and more.

Exposes the Porkbun v3 API as MCP tools for AI agents to manage domains, DNS, SSL, URL forwarding, and account settings.

A production-ready MCP server that wraps Nmap to enable AI agents to perform automated network security assessments, including port scanning, host discovery, service detection, OS fingerprinting, and vulnerability scanning.

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.

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 autonomously manage network devices using Nornir, supporting inventory filtering, parallel command execution, and configuration deployment across SSH, REST API, and serial connections.

A Model Context Protocol (MCP) server that provides comprehensive WHOIS lookup capabilities using the IP2WHOIS API. This server allows AI agents to query domain registration details, including expiry dates, registrar information, and registrant data.

Enables LLM agents to query SecurityTrails for DNS history, subdomain enumeration, WHOIS (current and historical), SSL certificates, and IPv4 intelligence via 17 read-only tools.

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.

Network diagnostics tool for AI agents that provides DNS lookup, IP geolocation, SSL certificate inspection, WHOIS queries, and HTTP latency testing.

Provides tools for AI agents to audit websites, including stack detection, DNS snapshots, and security checks.

Enables AI agents to audit email and domain security (SPF, DKIM, DMARC, etc.) for any domain without requiring API keys.
