Optional settings from the registry entry, left out of the block above: 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).

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 139 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 in the form 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 139 times in the last week. Week over week that is +136%. 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, 264 stars on GitHub and 6 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
