insertTable · Google Workspace MCP Server MCP: Risk & Policy

WHAT IT DOES

What insertTable does on Google Workspace MCP Server

AI agents use insertTable to create or update resources in Google Workspace MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Workspace MCP Server environment.

WHY IT NEEDS A POLICY

Why insertTable needs a policy

This tool creates new data structures (tables) within a Google Workspace document/sheet. It is reversible (tables can be deleted), so it falls under Write rather than Destructive. The severity is medium because inserting tables at incorrect indices or with large dimensions could disrupt document formatting or consume resources, but the operation is not inherently dangerous or financial in nature.

From the tool's definition Tool name 'insertTable' and description 'Inserts a new table with the specified dimensions at a given index' indicate creation of new structured content within a document or spreadsheet.

insertTable Rate-limited

insertTable stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
