AI agents call GOOGLEDOCS_LIST_SPREADSHEET_CHARTS_ACTION to retrieve information from Google Docs without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though GOOGLEDOCS_LIST_SPREADSHEET_CHARTS_ACTION only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.
