merge_paragraphs · Google Connections MCP: Risk & Policy

WHAT IT DOES

What merge_paragraphs does on Google Connections

AI agents use merge_paragraphs 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 merge_paragraphs needs a policy

The tool modifies document content by combining paragraphs, which is a reversible write operation. Without a description, confidence is reduced, but the naming pattern and server context strongly indicate document modification. Severity is medium because unintended merges could alter document structure, though changes can typically be undone via version history.

From the tool's definition Tool name 'merge_paragraphs' suggests modifying document content (Docs API). Sibling tools like 'append_to_doc' and 'batch_update_doc' confirm this server performs write operations on Google Workspace data.
