"author:ekixuweqohef49-boop" matching MCP servers:

A zero-dependency stdio MCP server that lets a model set its own QQ avatar from an image the user just sent (by message ID, URL, local path, or base64) and update its nickname or signature, fetching, magic-number validating, and uploading the image entirely on the local host instead of pushing base64 into the model context. All calls are locked to the owner's private chat, with group-chat attempts rejected and no parameter able to override the owner.
