What the code does

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a file or shell call exnos_tabs.tab → server/exnos-mcp.cjs:613

function saveControl(r) { try { fs.writeFileSync(recFile(r.id, '.json'), JSON.stringify(recInfo(r))); } catch {} }

Exnos — questions

Answers built from our own checks of this server.

Why is there no uptime for Exnos?

Exnos 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 @golproductions/exnos was installed 92 times last week.

How do I connect Exnos?

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 @golproductions/exnos straight from npm; nothing to host, nothing to sign up for.

How many people use Exnos?

The npm package @golproductions/exnos was installed 92 times in the last week. Week over week that is -81%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Exnos open source?

No, and the distinction matters: it ships its own licence file rather than a standard open-source licence. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
