Read and write Slack with session tokens — no OAuth, no bot, no admin approval.
What the code does
We read the source, 18 h ago · rules 3dff92dd89df
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
этот файл ставится пользователю, но в репозитории его нет
childProcess.execFileSync(resolveBinaryPath(), process.argv.slice(2), {
path := filepath.Join(s.dir, filename)

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
