WHAT IT DOES

What appflowy_invite_members does on AppFlowy MCP

WHY IT NEEDS A POLICY

Why appflowy_invite_members needs a policy

The tool creates new member records in the workspace and assigns roles, which are data modifications. While this affects permissions and access control, it is reversible (members can be removed or roles changed). This does not delete data (not Destructive), execute arbitrary code (not Execute), or move money (not Financial).

From the tool's definition Tool description states 'Invite people to a workspace by email with a role' — this creates new workspace memberships and modifies access control lists, which are reversible write operations.
