Naming stalls on the checking, not the ideas: the domain is free but the handle is gone, or the reverse. Doing every surface in one call — and generating variations to check alongside — is what lets a shortlist survive contact with reality.
A Python MCP server that checks availability of domain names, social media handles and subreddit names, returning clean JSON.
- Domains checked over RDAP with no key, or through NameSilo for prices alongside availability
- Handles checked on Instagram, Twitter/X, Reddit, YouTube, TikTok, Twitch and Threads
- Subreddit names checked against Reddit
- Name combinations generated and everything checked at once
- Results as clean JSON, meant to be consumed by a program rather than read off a page
Add it to your client as a user-level server running `uvx internet-names-mcp`, and it works immediately over RDAP with nothing else. Domain pricing needs a free NameSilo key: the package ships a setup command that stores it for you, in the macOS keychain or in a config file under your home directory, and an environment variable works instead.
One command — claude mcp add --scope user internet-names-mcp uvx internet-names-mcp
