AI agents call get_comments to retrieve information from Notion without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing comment data from a Notion page without creating, modifying, or deleting any content. It is a straightforward read operation with minimal security risk, as it only exposes comments that are already visible within the workspace context.
From the tool's definition Tool name 'get_comments' and description 'Get all comments on a page' indicate data retrieval with no modification or side effects.
