This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: THREE_WS_BASE (Base URL of the three.ws API that serves POST /api/concierge, and the origin the generated embed snippets point at. Override only when self-hosting or targeting a preview deployment.), THREE_WS_TIMEOUT_MS (Per-request timeout in milliseconds for the concierge answer call. The answer streams over a free-first LLM chain that can fail over across providers, so the default leaves room for one slow rung.), CONCIERGE_PAGE_TIMEOUT_MS (Timeout in milliseconds for fetching a page that concierge_ask grounds its answer in. Separate from the answer timeout so a slow site cannot consume the whole call.). The author declared them in the registry entry; get the values from the project itself.

three.ws Concierge — questions

Answers built from our own checks of this server.

Why is there no uptime for three.ws Concierge?
three.ws Concierge 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/concierge-mcp was installed 204 times last week.
How do I connect three.ws Concierge?
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/concierge-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use three.ws Concierge?
The npm package @three-ws/concierge-mcp was installed 204 times in the last week. Week over week that is +1039%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is three.ws Concierge 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.
