WHAT IT DOES

What generate_ui5_fragment does on MCP SAPUI5 Server

AI agents use generate_ui5_fragment to create or update resources in MCP SAPUI5 Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP SAPUI5 Server environment.

WHY IT NEEDS A POLICY

Why generate_ui5_fragment needs a policy

This tool creates new SAPUI5 fragment code artifacts. While it produces output, it is a reversible operation (generated files can be modified or deleted), making it a Write action rather than Destructive. The severity is low because fragment generation is a standard development task with no data deletion, side effects, or external system modifications.

From the tool's definition Tool generates an XML SAPUI5 fragment skeleton—a template creation operation that creates new file content. The verb 'generate' combined with 'skeleton' indicates code artifact creation without destructive implications.
