This one needs environment variables set before it will start: THREE_WS_BASE (Base URL of the three.ws API that serves /api/sns and /api/threews/subdomain. Override only when self-hosting or targeting a preview deployment.), THREE_WS_TIMEOUT_MS (Per-request timeout in milliseconds. Resolution and availability checks hit a Solana RPC pool, so the default leaves room for a cold lookup.). The author declared them in the registry entry; get the values from the project itself.

three.ws Naming — questions

Answers built from our own checks of this server.

Why is there no uptime for three.ws Naming?

three.ws Naming runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @three-ws/naming-mcp was installed 203 times last week.

How do I connect three.ws Naming?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @three-ws/naming-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use three.ws Naming?

The npm package @three-ws/naming-mcp was installed 203 times in the last week. Week over week that is +368%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is three.ws Naming open source?

Yes — it is published under the Apache-2.0 licence, written in JavaScript and 194 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
