Netease Yunxin IM MCP. Administer high-concurrency chatrooms and users.

The Netease Yunxin IM MCP Server gives your AI agent full admin control over live chat rooms and user accounts within the Netease network. You're running a high-concurrency messaging system, so this tool lets you manage everything—from basic text sends to complex moderation actions—without ever having to write server code.

It’s built for massive Asian chat environments.

When you need to handle users and accounts, the agent can generate a new IM user profile using create_im_user, or it'll update an existing account's details like display names with update_im_user. You've got full control over access levels; if someone screws up, the agent can block their entire IM account using block_im_user, and when they clean up their act, you can reverse that status with unblock_im_user.

For managing the chat environment itself, you'll find tools for the whole lifecycle of a room. You can spin up a brand-new, large-scale chatroom instance using create_chatroom, and when it's dead and gone, you destroy it completely with destroy_chatroom. Before moderation hits, you pull a list of everyone currently in a specific room by calling get_chatroom_members; this gives you the exact roster of active users.

If someone starts spamming or harassing people, the agent can mute them using mute_chatroom_member so they can't send another message.

Communication isn’t just about simple text. You can dispatch plain text messages between two specific users (P2P) using send_text_message. For richer interactions—like sending structured data or attaching complex payloads—the agent uses send_custom_message, which accepts a full JSON payload to ensure the recipient gets exactly what you send it. When misconduct happens, if a message needs to vanish from the history, the agent can remove it entirely using recall_message.

Your ability to control messages and users is comprehensive: besides sending text or structured data payloads, you've got administrative tools to keep the rooms clean. The entire system allows your AI client to operate like a moderator with access to every key function required for massive chat operations.
