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.
execFile(this.adb, ['devices'], { signal, env, timeout: 10000, maxBuffer: 1_000_000 }, (error, stdout) => error ? reject(new Stop('adb_unavailable')) : resolve(stdout));
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.
