Get information about a Google Spreadsheet including sheets and properties
AI agents call get_sheet_metadata to retrieve information from Sheeter MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves spreadsheet metadata (sheets list, properties) with no side effects. It is purely informational and read-only, making it a Read category risk with low severity. The blast radius of misuse is minimal—an attacker gains visibility into spreadsheet structure but cannot modify, delete, or execute operations.
