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.
const kindDir = path.join(base, kind);
const child = spawn(process.execPath, [entry, "--broker"], {
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 one needs environment variables set before it will start:
SWEBSY_AGENT_PORT (Port the local relay listens on (default 37373)), SWEBSY_AGENT_DIR (Where screenshots and exports land (default: .swebsy-agent in the workspace)), SWEBSY_APP_URL (Studio origin used for the pairing link (default https://studio.swebsy.com; set this for local or self-hosted Studio)), SWEBSY_NO_OPEN (Set to skip auto-opening the pairing link in the browser).
The author declared them in the registry entry; get the values from the project itself.
