Overview

The bilibili-mcp-server MCP server connects AI agents to Bilibili through 31 tools for video search, metadata, subtitles, danmaku, comments, users, articles, notifications, live rooms, authentication, and downloads. It runs through npx or a global npm installation and supports Cookie-based authentication or QR-code login. Use it to research Bilibili content, monitor creators, manage account interactions, inspect live streams, or save videos and articles locally. Authenticated actions such as commenting, following, sending danmaku, and downloading require appropriate account or system configuration.

Use cases

  • Search Bilibili videos and compare engagement metrics
  • Inspect a creator’s latest videos, dynamics, and articles
  • Review comments, danmaku, subtitles, and unread notifications
  • Monitor live rooms and return screenshots for visual analysis
  • Download Bilibili videos or articles for personal backup

Key features

  • Video search, metadata, subtitles, comments, danmaku, and hot lists
  • Bilibili user profiles, creator content, favorites, and social graphs
  • Comment, follow, unfollow, and danmaku actions
  • QR-code login, Cookie refresh, reply detection, and notifications
  • Live-room metadata and screenshot capture
  • Video and Markdown article downloads

How Bilibili MCP Server works

What bilibili-mcp-server does

bilibili-mcp-server exposes Bilibili functions through the Model Context Protocol. Its 31 tools cover public content discovery, account-aware actions, creator activity, live rooms, notifications, authentication, and local downloads.

For video workflows, it can search Bilibili, inspect video statistics and metadata, retrieve comments and danmaku, and return AI-generated subtitle text with timestamps. Search results use Bilibili’s ranking behavior rather than a strict publication-time order, so finding a creator’s newest uploads is better handled by locating the creator’s UID first and then calling the creator video-list tool.

Creator and account tools provide user profiles, uploaded videos, favorites, dynamics, articles, following lists, followers, notifications, and new-reply detection. Write operations include publishing or deleting comments, liking comments, following or unfollowing creators, and sending danmaku.

How it works

The package starts as an MCP process over the command line. An MCP client launches it with npx -y bilibili-mcp-server or invokes the globally installed command, then calls individual tools with their documented parameters.

Authentication can use Bilibili Cookie values supplied through environment variables or a .env file. Alternatively, an agent can call bilibili_login to obtain a QR-code image and login key, have the account scan the code in the Bilibili mobile app, and poll with bilibili_login_check. Successful QR login saves the resulting Cookie. Cookie refresh can be triggered with bilibili_refresh_cookie when a refresh token is configured.

The live screenshot tool returns room metadata and a keyframe for models that can process images. Text-only models can use the accompanying metadata but cannot interpret the picture. Video downloads retrieve separate video and audio streams and use ffmpeg to combine them into an MP4; article downloads save content as Markdown and can optionally include images.

Setup and configuration

Node.js 22 or newer is required. Install ffmpeg separately if video downloads are needed. The package can be run directly:

Terminal
npx bilibili-mcp-server

Or install it globally with npm and run bilibili-mcp-server.

Set these required values using the shell environment or a project-level .env file:

  • BILIBILI_SESSDATA
  • BILIBILI_BILI_JCT
  • BILIBILI_DEDE_USER_ID

Optional settings include BILIBILI_REFRESH_TOKEN for automatic Cookie renewal, BILIBILI_FULL_COOKIE for functions such as hot-search access, BILIBILI_AUTO_REFRESH, BILIBILI_COOKIE_FILE, and BILIBILI_DETECT_FILE. The Cookie fields can be obtained from Bilibili’s browser developer tools. The refresh token is available from the Bilibili site’s stored ac_time_value value.

A client configuration passes the command and credentials in the MCP server’s env object. QR login is available when manually copying Cookie values is undesirable.

Tools and capabilities

  • Search videos and hot-search terms; inspect popular videos.
  • Read video details, comments, subtitles, and danmaku.
  • Publish, delete, and like comments.
  • Read user profiles, videos, favorites, dynamics, articles, followings, and followers.
  • Follow or unfollow creators and monitor replies or unread notifications.
  • Query live-room status and return a current screenshot.
  • Send danmaku, refresh authentication, and perform QR login.
  • Download videos, articles, and a list of completed downloads.

Limitations and notes

Bilibili may apply strict risk controls to account actions. The project advises limiting danmaku sending to five messages per day and avoiding bursts of follow or unfollow operations. Downloaded content is intended for personal backup and should not be redistributed. The live-room popularity value represents a heat metric rather than verified viewer count. Video downloads require ffmpeg, and image interpretation from live screenshots requires a vision-capable model.
