WHAT IT DOES

What remove_key_mapping does on Unreal-MCP

AI agents call remove_key_mapping 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_key_mapping is rated Critical

The tool removes key mappings, which are configuration data in Unreal Engine. Removal of mappings is irreversible and cannot be easily undone within the tool's scope—an AI agent misusing this could delete critical input bindings needed for game functionality.

From the tool's definition Tool name 'remove_key_mapping' indicates deletion/removal of input key mappings. Sibling tools like 'add_key_mapping' suggest this modifies Unreal Engine input configuration. The 'remove' verb indicates irreversible deletion of configuration data.

RECOMMENDED RULE

The rule that runs remove_key_mapping 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_key_mapping, this is the rule to start with:

remove_key_mapping Hidden

remove_key_mapping 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_key_mapping call is checked against it from then on.
