Arc Security — questions

Answers built from our own checks of this server.

Why is there no uptime for Arc Security?
Arc Security 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 arc-security-mcp was installed 82 times last week.
Is Arc Security still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Arc Security?
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 arc-security-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Arc Security?
The npm package arc-security-mcp was installed 82 times in the last week. Week over week that is +14%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
