Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to 17nas.com. It runs from a package rather than a hosted endpoint, so there is no endpoint to match against that domain.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server offering free network diagnostics: public IP info, DNS record lookups, and IPv6 reachability checks.

What you can do: Look up public IP details: address, IPv4/IPv6 protocol, country, ASN and location
Query DNS records (A, AAAA, MX, TXT, NS, CNAME) over DNS-over-HTTPS
Check IPv6 reachability by resolving AAAA records and testing TCP connectivity over IPv6 versus IPv4
When to use it: Useful when you want an assistant to answer quick networking questions during a session — checking what IP a host resolves to, inspecting DNS records, or verifying whether a host is reachable over IPv6.
Requirements: Runs as a local process over stdio, installed from the npm package 17nas-mcp-server (Node.js runtime). No API key or environment variables are declared. Network access is needed for the IP info API and DNS-over-HTTPS queries. Desktop client only.

Before you install

Public IP lookups are sent to the 17NAS API, and DNS queries go to a DNS-over-HTTPS resolver, so queried hostnames and your public IP leave your machine. The tools are read-only diagnostics; no credentials are requested.

Installation

In SourceWeft

Open 17NAS Network Tools in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
