MCP SERVERBring Bilibili video and post comments, including nested replies, into your assistant for reviewing audience discussions.
Bilibili-Comments-MCP lets your assistant read comment threads on Bilibili videos and posts. It retrieves comments in pages, with optional nested replies and Markdown or JSON output, so you can review discussions in your chat or work with the returned data. Its tools read comments without posting replies or changing content.
The server runs on your computer and requires a valid Bilibili session cookie. Access to comments depends on the signed-in account’s permissions.
When you want to understand how viewers responded to a video, ask your assistant to retrieve comments by time or popularity and include nested replies. You get comments and their follow-up discussions together for review, with pagination to examine more responses.

When a Bilibili post draws questions or discussion, top-level comments alone can miss the exchanges beneath them. Retrieve the post’s comments with nested replies so your assistant has those exchanges available when you ask it to review the conversation.
