WHAT IT DOES

What google_docs_append_text does on Sage MCP

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

RISK

Why google_docs_append_text is rated Medium

This tool modifies an existing Google Doc by adding content to it. This is a reversible write operation (appended text can be removed), placing it in the Write category. Misuse could result in unwanted content being added to documents, but it does not delete or irreversibly destroy data.

RECOMMENDED RULE

The rule that runs google_docs_append_text safely

google_docs_append_text Rate-limited

google_docs_append_text 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.
