# Hashtag Generator — MCP tool `findutils:hashtag_generator`

Generate relevant hashtags from keywords using a built-in, rule-based database (no AI): matches keywords against topic categories, scores popular and niche tags, adds compound and suffix variants, and caps the list at the platform limit (Instagram 30, Twitter 5, TikTok 20, LinkedIn 10, YouTube 15). Returns the hashtags, a space-joined string, and the tags grouped by source.
