What is the Internetnamesmcp MCP server?

Internetnamesmcp MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. An MCP server for checking availability of domain names, social media handles, and subreddits. Returns clean JSON responses suitable for programmatic use.

What you get

  • Domain names — - Check availability via RDAP (free) or NameSilo API (free, but requires API key - responses include domain prices too)
  • Social media handles — - Instagram, Twitter/X, Reddit, YouTube, TikTok, Twitch, Threads
  • Subreddits — - Check if subreddit names are available on Reddit
  • Comprehensive search — - Generate name combinations and check everything at once

Setting it up

@modelcontextprotocol/inspector on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration and credentials

You will need one environment variable: NAMESILO_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by drewster99; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the internetnamesmcp mcp server does with a few real requests.
