Bilibili Subtitle Fetch

一个用于获取 Bilibili 视频字幕的 MCP Server，支持语言和输出格式选项。

uv tool install --python 3.13 bilibili-subtitle-fetch

支持以下输入：

  • BV 号，例如 BV1fz4y1j7Mf
  • 标准视频链接，例如 https://www.bilibili.com/video/BV1fz4y1j7Mf?p=2
  • 短链，例如 https://b23.tv/FAm7Xn4

配置

凭据配置文件

首次使用时执行 bilibili-subtitle-fetch init，然后粘贴你的 Bilibili Cookie。

默认配置文件路径：

  • Windows: %APPDATA%\bilibili-subtitle-fetch\config.toml
  • Linux/macOS: ~/.config/bilibili-subtitle-fetch/config.toml

也可以通过 --config /path/to/config.toml 指定自定义路径。

配置文件会在 [credential] 下保存这些字段：

  • sessdata - 访问需要登录态的字幕接口时必需
  • bili_jct - 自动刷新时必需
  • ac_time_value - 自动刷新时必需
  • buvid3、buvid4、dedeuserid - 可选，但建议一并保存

当 sessdata、bili_jct 和 ac_time_value 都存在时，服务会在发起需要登录态的请求前自动检查是否需要刷新 Cookie，并将新值回写到 config.toml，不需要手动执行刷新命令。

ASR 配置 (可选)

配置文件同样支持 [asr] 段落配置默认的音频转写行为：

  • enable_asr - 是否开启 ASR 回退 (true/false)。开启后，如果视频未提供自带字幕，程序会自动下载音频并生成字幕。
  • model_size - Whisper 模型大小，默认为 base。也可以选用 tiny、small 等。

运行参数

  • --preferred-lang - 覆盖默认字幕语言
  • --output-format - 覆盖默认输出格式
  • --config - 使用自定义配置文件路径

CLI 用法

先执行 bilibili-subtitle-fetch init 配置 Cookie，然后可以直接在终端获取字幕：

bilibili-subtitle-fetch fetch BV1fz4y1j7Mf
bilibili-subtitle-fetch fetch "https://www.bilibili.com/video/BV1fz4y1j7Mf?p=2"

命令会把字幕输出到标准输出，并在成功后自动复制到剪贴板。

可选参数：

  • --preferred-lang - 指定优先字幕语言
  • --output-format text|timestamped - 指定输出格式
  • --no-clipboard - 只输出，不复制到剪贴板
  • --asr - 强制启用 ASR 语音识别回退
  • --no-asr - 强制关闭 ASR 语音识别回退
