AI agents call gmail.getLabelInfo to retrieve information from Gmail 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 label metadata and message counts, which are read-only operations. There is no data modification, deletion, financial impact, or code execution. The blast radius of misuse is minimal—an agent could only retrieve information about label statistics, not access sensitive email content, modify messages, or perform destructive actions. It falls clearly within the Read category.
From the tool's definition Tool name 'getLabelInfo' and description 'Get information about a label including message counts' indicate a retrieval operation with no modification or deletion of data.
