Get help on using reminders
AI agents call help to retrieve information from MCP Reminders without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only tool that returns usage information or documentation. It neither modifies state, executes operations, nor has any destructive or financial implications. The minimal blast radius if misused (an agent might retrieve unhelpful documentation) makes this low severity.
From the tool's definition Tool name 'help' and description 'Get help on using reminders' indicate a documentation/informational retrieval function with no side effects on data or operations.
