AI agents call get_crypto_news to retrieve information from Agenti without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure read operation that fetches and returns data without modifying, executing code, deleting, or moving money. While the server enables financial operations (crypto transactions), this specific tool only retrieves news headlines. No data is modified, created, or destroyed. Low severity because misuse (e.g., an agent reading news excessively) has minimal security impact.
