Subtitle Clean MCP tool
findutils:subtitle_clean Clean the text of a SubRip (.srt) or WebVTT (.vtt) caption file without touching its timing: strip HTML tags such as <i> and <font>, ASS/SSA override blocks such as {\an8} that leak into exported files, and optionally SDH descriptions in brackets ([music], (applause)) and speaker labels ("JOHN:"). Cues that end up empty are dropped and counted, never written as blank cues. Every start and end time is kept exactly. The output keeps the input format unless output_format is "srt".
