AI agents call get_feeds to retrieve information from Weibo MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user feed data from Weibo without creating, modifying, deleting, or executing operations. It is a simple read operation that queries existing public or authorized user content. The low severity reflects minimal risk if misused by an AI agent—it can only expose publicly available or user-accessible feed information.
From the tool's definition Tool name 'get_feeds' and description '获取指定微博用户的最新动态和帖子' (retrieve latest updates and posts from specified Weibo user) indicate data retrieval with no modification or deletion.

{
"version": "1",
"default": "deny",
"tools": {
"get_feeds": {}
}
}get_feeds is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
