WHAT IT DOES

What appflowy_upsert_row does on AppFlowy Cloud MCP Server

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

WHY IT NEEDS A POLICY

Why appflowy_upsert_row needs a policy

Upsert operations modify data reversibly: they can create new rows or update existing ones, but changes are not permanent deletions and can be undone or corrected through subsequent writes. This places it in the Write category rather than Execute (no arbitrary code execution), Destructive (not irreversible), or Financial (no monetary impact).

From the tool's definition Tool name 'appflowy_upsert_row' and description 'Update existing row or create if it doesn' indicate reversible row modification—either updating an existing row or creating a new one. The 'upsert' pattern (update or insert) is a standard write operation.
