Nothing serious here today

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

Security Engineer — questions

Answers built from our own checks of this server.

Why is there no uptime for Security Engineer?
Security Engineer 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 @guardbee/mcp-security-engineer.
How do I connect Security Engineer?
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 @guardbee/mcp-security-engineer straight from npm; nothing to host, nothing to sign up for.
Is Security Engineer open source?
Yes — it is published under the MIT licence, written in TypeScript, 2 stars on GitHub and 11 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
