Nothing serious here today

Today is the operative word: we check Syncpen 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: SYNCPEN_API_KEY (Your Syncpen API key (starts with sp_). Create one at https://www.syncpen.io/settings/api-keys.). The author declared them in the registry entry; get the values from the project itself.

Syncpen — questions

Answers built from our own checks of this server.

Why is there no uptime for Syncpen?

Syncpen 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 syncpen-mcp was installed 64 times last week.

How do I connect Syncpen?

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

How many people use Syncpen?

The npm package syncpen-mcp was installed 64 times in the last week. Week over week that is -50%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Syncpen open source?

Yes — it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
