Today
AI agents call getTodayContext to retrieve information from Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries or retrieves data from the knowledge base without modifying, deleting, or executing external operations. It falls squarely into the Read category with low severity due to its informational, non-destructive nature.
From the tool's definition Tool name 'getTodayContext' and description 'Today' indicate retrieval of context or information about the current day's tasks, notes, or goals from the knowledge base. No modification, deletion, or external execution is implied.
