WHAT IT DOES

What update_data_table_row does on Unreal-MCP

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

RISK

Why update_data_table_row is rated Medium

This tool modifies data within Unreal Engine's data tables—a reversible write operation that changes game configuration or asset data. It is not destructive (row is not deleted), not financial, and not arbitrary code execution. However, it carries medium severity because corrupting data tables could break game logic, rendering, or gameplay mechanics, affecting project stability.

From the tool's definition Tool name 'update_data_table_row' and description 'Update specific fields on an existing row (partial update)' indicate modification of existing game data structures.
