WHAT IT DOES

What remove_mapping_modifier does on Unreal-MCP

AI agents call remove_mapping_modifier to permanently remove resources in Unreal-MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why remove_mapping_modifier is rated Critical

Removing a modifier from a mapping is a destructive operation that deletes configuration data from the Input Mapping Context. While the Unreal Editor may have undo history, MCP-driven operations are often not easily reversible and the modifier configuration is deleted rather than just modified. Severity is medium as it affects editor asset configuration but not runtime data or financial systems.

From the tool's definition 'Remove a modifier from a mapping' — irreversibly removes a modifier configuration from an Input Mapping Context

RECOMMENDED RULE

The rule that runs remove_mapping_modifier safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unreal-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remove_mapping_modifier, this is the rule to start with:

remove_mapping_modifier Hidden

remove_mapping_modifier is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect Unreal-MCP, apply this rule, and every remove_mapping_modifier call is checked against it from then on.
