Capabilities

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.

        err = os.WriteFile(filepath.Join(logPath, filename), []byte(log.String()), 0644)
Touches key and credential files src/segments/docker.go:51
        filepath.Join(d.env.Home(), ".docker/config.json"),
Touches key and credential files src/segments/docker.go:51
        filepath.Join(d.env.Home(), ".docker/config.json"),

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

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.
