Sketchdex runs on your own machine — the client starts it, so there is no endpoint to ping. 53 installs a week from npm. Last commit 4 Sep 2026.

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.
spawn(cmd, cmdArgs, { stdio: "ignore", detached: true }).unref();
return fs.readFile(path.join(root, topic.file), "utf8");
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
SKETCHDEX_VAULT (Folder where scenes are stored. Default: ~/Documents/sketchdex), SKETCHDEX_BROWSER (Path to a Chromium-based browser binary used for render_scene. Default: the first of Chrome, Chromium, Edge or Brave found on the machine).
The author declared them in the registry entry; get the values from the project itself.
