AI agents call get_followers 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.
The tool retrieves follower information from Weibo, which is a read operation with no side effects. However, severity is medium (not low) because mass scraping of social media user relationship data may enable harassment, stalking, or privacy violations if misused by an AI agent at scale.
From the tool's definition Tool name 'get_followers' indicates retrieval of follower list data. Server description emphasizes 'scraping' and 'retrieve' operations with sibling tools like 'get_profile', 'get_feeds', and 'search_users' all being read operations.

{
"version": "1",
"default": "deny",
"tools": {
"get_followers": {}
}
