What the code does
We read the source, 3 d ago · rules 995398eba69f
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.
data, err := os.ReadFile(filepath.Join(root, compactionAttemptFile))
dimSelect = "coalesce(" + ref.stringSQL() + ",'') AS dim"
prefix = append(prefix, "dim")

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.
