Nothing serious here today

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

Enables attestify_trust_submit_evidence and attestify_trust_verify), TRUST_PRIVATE_KEY (That agent's Ed25519 private key (base64url), from the same trust-init run. Never leaves this server except as a signature).

Attestify OS — questions

Answers built from our own checks of this server.

Why is there no uptime for Attestify OS?
Attestify OS 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 attestify-mcp was installed 67 times last week.
How do I connect Attestify OS?
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 attestify-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Attestify OS?
The npm package attestify-mcp was installed 67 times in the last week. Week over week that is +24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Attestify OS open source?
Yes — it is published under the MIT licence, written in JavaScript 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.
