AI agents call get_version to retrieve information from Things 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 version information without modifying, deleting, or executing any operations. It has no side effects and is purely informational. The low severity reflects that version metadata cannot be leveraged to cause harm even if misused by an AI agent.
From the tool's definition Tool name 'get_version' and description 'get Things app and URL Scheme version information' indicate a retrieval operation that returns metadata about the application.
