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.

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: ATTESTIFY_BASE_URL (Base URL of the deployed Attestify app.), ATTESTIFY_API_KEY (Tenant API key issued via POST /api/keys, sent as X-API-Key on /api/run calls.), TRUST_AGENT_ID (Attestify Trust agent ID, from a one-time `npx attestify trust-init` run. 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.). The author declared them in the registry entry; get the values from the project itself.

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 57 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 with the file path 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 57 times in the last week. 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?
We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
