What the code does

We read the source, 1 d ago · rules 995398eba69f

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Deletes files or strips permissions src/Draughtsman.Server/Hardening/DataFolderPermissions.cs:100

                ? " Other users can also add, rename and delete files in it (the README used to suggest chmod 777 for Docker; use chown to the container's uid, 10001, instead)."

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.

Checks whether it runs in a sandbox src/Draughtsman.Server/Hosting/HostKind.cs:38

        if (string.Equals(environment("DOTNET_RUNNING_IN_CONTAINER"), "true", StringComparison.OrdinalIgnoreCase) || fileExists("/.dockerenv"))

Runs an external command src/Draughtsman.Server/Cli/ServiceExecutor.cs:147, src/Draughtsman.Server/Export/ProcessTable.cs:96, src/Draughtsman.Server/KeyRing/KeyEncryptionKeySources.cs:163 и ещё 2

        var start = new ProcessStartInfo(fileName) { RedirectStandardOutput = true, RedirectStandardError = true };

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

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Draughtsman and you get told the day something new turns up.

Draughtsman — questions

Answers built from our own checks of this server.

Why is there no uptime for Draughtsman?

Draughtsman runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is Draughtsman open source?

Yes — it is published under the AGPL-3.0 licence, written in C# and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
