Get tweets from your home timeline (Following)
AI agents call get_latest_timeline to retrieve information from X (Twitter) 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 tweets from a user's home feed without creating, modifying, or deleting any data. It has no side effects and falls squarely into the Read category. The severity is low because retrieving publicly available or user-accessible timeline data poses minimal security risk, even if exposed to an AI agent.
