Почему webbrowser.open не работает с сервером mcp? [закрыто] ⇐ Python

[Anonymous]

• Краткий контекст: Я создаю локальный агент Python с использованием 3B-модели на основе llama.cpp и инструментов в стиле MCP. Один инструмент должен открывать поиск YouTube в браузере.
• Что работает

• Инструмент называется
• URL возвращается правильно.

• Что не так

• Код: Выделить всё

  webbrowser.open

  ничего не делает при вызове внутри инструмента/сервера.

• Среда

• ОС (например, Ubuntu 24.04)
• Среда рабочего стола (GNOME/KDE/WSL/headless/etc.)

• Конкретный вопрос: Плохая ли идея вызывать webbrowser.open изнутри серверного процесса? Должен ли я перенести логику открытия URL-адресов на сторону клиента? Есть какие-нибудь рекомендации для этого при локальной настройке?
• Код для контекста: Серверный метод для открытия браузера

"""Return a YouTube search URL for the given topic and *try* to open it."""
logger.debug(f"[TOOL] Searching YouTube for topic: {topic!r}")

query = quote_plus(topic)
url = f"https://www.youtube.com/results?search_query={query}"

try:
browser = web.get()
logger.debug("[TOOL] Using browser handler:", browser)
except web.Error as e:
logger.debug("[TOOL] webbrowser.get() failed:", e)

opened = web.open(url, new=2)

return url
