WHAT IT DOES

What latest_notification does on Open Stocks MCP

AI agents call latest_notification to retrieve information from Open Stocks MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

From the tool's definition Tool name is 'latest_notification' and description states 'Gets the most recent notification' — a pure retrieval operation with no mutation, execution, or financial transaction.
