Today is the operative word: we check three.ws Scenes every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: THREE_WS_BASE (Base URL of the three.ws API that serves /api/diorama. Override only when self-hosting or targeting a preview deployment.), THREE_WS_TIMEOUT_MS (Per-request timeout in milliseconds. compose_scene runs a server-side LLM chain, so the default is generous.). The author declared them in the registry entry; get the values from the project itself.

three.ws Scenes — questions

Answers built from our own checks of this server.

Why is there no uptime for three.ws Scenes?

three.ws Scenes 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/scene-mcp was installed 205 times last week.

How do I connect three.ws Scenes?

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/scene-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use three.ws Scenes?

The npm package @three-ws/scene-mcp was installed 205 times in the last week. Week over week that is +693%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is three.ws Scenes 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.
