WHAT IT DOES

What list_input_mapping_contexts does on Unreal-MCP

AI agents call list_input_mapping_contexts to retrieve information from Unreal-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_input_mapping_contexts is rated Low

This tool queries and enumerates existing input mapping context assets in the Unreal Engine editor. It performs read-only retrieval with optional filtering, has no side effects, and cannot modify, execute, or delete data. The blast radius of misuse is minimal — an AI agent could only enumerate input mappings, posing negligible security risk.

From the tool's definition Tool name contains 'list' and description states 'List all UInputMappingContext assets, optionally filtered' — this is a query operation that retrieves data without modification.

RECOMMENDED RULE

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

list_input_mapping_contexts Allowed

list_input_mapping_contexts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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