WHAT IT DOES

What appflowy_save_page does on AppFlowy MCP

WHY IT NEEDS A POLICY

Why appflowy_save_page needs a policy

This tool creates new pages in AppFlowy, which modifies the workspace state by adding content. It is not destructive (pages can be deleted/restored), not Execute (no arbitrary code/commands), not Financial, and not merely Read. Write category is appropriate. Severity is medium because creating unwanted pages could clutter workspaces or consume quota, but the impact is easily reversible and limited in scope.

From the tool's definition Tool description states 'Save generated content as a new AppFlowy page' — this creates new data in the workspace. The term 'Save' and 'new' indicate a Write operation that creates a reversible resource.
