WHAT IT DOES

What apply_project_patch does on MCP SAPUI5 Server

AI agents use apply_project_patch 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 apply_project_patch needs a policy

This tool modifies files within the workspace (Write category) but includes rollback capability, making changes reversible rather than destructive. The emphasis on 'safe' changes and explicit rollback metadata creation mitigates severity to medium rather than high. While file modifications can impact project state, the reversibility and rollback mechanism prevent this from being Destructive.

From the tool's definition Tool description states it 'Apply[s] one or more safe workspace file changes and create[s] rollback metadata for later restore.' The keywords 'apply changes' and 'create rollback metadata' indicate file modification with reversibility.
