Feishu Im Read

Pulls messages from Feishu IM conversations with solid flexibility around what you need. You can fetch chat history by conversation or user ID, read threaded replies, search across multiple chats by keyword or sender, and download images and files from messages. It handles pagination properly when there are more results, supports time filtering with relative ranges like "last 3 days" or precise timestamps, and runs with user permissions so you only see what you're allowed to. The threading support is actually useful since it can auto-expand replies to give you full context. Main gotcha is you can't time-filter thread messages due to API limits, and there's a 100MB cap on file downloads.
