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.
пакет threadline-mcp ссылается на jkheadley/instar
result = subprocess.run(
review_path = os.path.join(PENDING_REVIEW_DIR, f"{delta_id}.json")
const child = spawn(command, args, {
el.innerHTML = arr.map((p) => renderCard(p, opts)).join('');
const files = fs.readdirSync(this.compactedDir)
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.
