Nothing serious here today

Today is the operative word: we check Excaliwow 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: EXCALIWOW_TOKEN (Excaliwow Personal Access Token with read and write capabilities. Add delete only for trash and restore tools.), EXCALIWOW_API_URL (Optional Excaliwow API origin. Leave unset to use https://excaliwow.com.). The author declared them in the registry entry; get the values from the project itself.

Excaliwow — questions

Answers built from our own checks of this server.

Why is there no uptime for Excaliwow?

Excaliwow 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 @excaliwow/mcp was installed 40 times last week.

How do I connect Excaliwow?

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 @excaliwow/mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Excaliwow?

The npm package @excaliwow/mcp was installed 40 times in the last week. Week over week that is +56%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Excaliwow open source?

Yes — it is published under the Apache-2.0 licence and 0 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.
