Search recent public tweets (read-only)
AI agents call search_tweets to retrieve information from 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 performs a query operation on publicly available tweet data and returns results without modifying, creating, or deleting anything. The read-only designation confirms no state changes occur. The low severity reflects minimal risk—an AI agent misusing this could at worst generate numerous search requests, which is rate-limited by the Twitter API itself.
From the tool's definition Tool explicitly described as 'Search recent public tweets (read-only)', which retrieves data without side effects.
