"Python runner with streamable HTTP support" matching MCP servers:

Exposes any stdio-based MCP server over the MCP Streamable HTTP transport so remote clients can reach it, spawning an isolated child process per session and gating access behind a secret URL path.

A reusable MCP server template for AI agents to operate SDN network controllers via tools, built on FastMCP with Streamable HTTP and stdio support.

Enables users to inspect local TCP and UDP listening sockets, identify which process owns a given port and whether it can be bound, find a port available to bind, and wait until a busy port frees up. Queries run through stdio without reading command lines, environments, or signaling other processes.

MCP server and CLI for UniFi Network controllers: clients, devices, WLANs, firewall, and health over stdio or streamable HTTP, with auth.

A local stdio MCP server that bridges remote Streamable HTTP MCP servers to MCP clients, enabling transport normalization and optional outbound HTTP proxy support for restricted networks.

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.

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.

Provides safe, read-only network diagnostics (ping, DNS, HTTP health, TLS expiry, port checks, traceroute, and fleet sweeps) for monitoring infrastructure.

Remote MCP server with 21 tools: 10 Domain Dossier checks (DNS, MX, SPF, DMARC, DKIM, TLS, redirects, headers, CORS, web-surface) plus 10 developer utilities (base64, JWT decode, DNS lookup, UUID v4/v7, URL encode/decode, JSON format, User-Agent parse, IP lookup) and a dossier_full aggregate. Served over Streamable HTTP.

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.

A domain security and privacy checker MCP server that runs locally, performing DNS, TLS, HTTP, and RDAP lookups to generate a scored report covering certificates, email authentication, DNS, and web security headers.

MCP server for ngsrv tunnels that exposes local HTTP ports on public HTTPS URLs, with tools for starting, listing, and stopping tunnels, and provisioning agent tokens.

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

Performs domain security posture checks including SPF, DKIM, DMARC, TLS, and HTTP security headers.

MCP server for managing VyOS routers via the VyOS HTTP API, allowing AI assistants to read config, set interfaces, firewall rules, VPNs, and more.

MCP server for discovering Kubernetes services and running kubectl port-forward sessions, optionally with separate log windows.

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 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.

Enables AI agents to interact with Charles Proxy for HTTP traffic analysis, supporting incremental harvest, checkpoint timelines, and rich filtering tools.

Provides read-only access to UniFi Network consoles for sites, devices, clients, vouchers, networks, Wi-Fi, and firewall configuration, with optional opt-in tools for controlled write operations and legacy controller support.
