batch_update_doc · Google Connections MCP: Risk & Policy

WHAT IT DOES

What batch_update_doc does on Google Connections

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

WHY IT NEEDS A POLICY

Why batch_update_doc needs a policy

batch_update_doc modifies document content (reversible operation), placing it in the Write category. Severity is high because batch updates to shared documents could affect multiple users and data integrity, though effects are reversible. Confidence is 0.85 rather than higher because the tool description is empty, requiring inference from context and naming convention.

From the tool's definition Tool name 'batch_update_doc' indicates batch modification of documents. Sibling tools like 'append_to_doc' and 'add_row' show this server performs Write operations on Google Workspace documents.
