Dump entity/actor data from WRAM - useful for analyzing game objects
AI agents call mgba_dump_entities to retrieve information from mGBA MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and extracts data from the emulator's working memory (WRAM) to analyze game entities and actors. It performs memory inspection without side effects, making it a Read operation. The blast radius is minimal as it only observes game state without modifying or executing anything. Confidence is high due to clear read-only semantics in the description.
From the tool's definition Tool name includes 'dump' and description states 'dump entity/actor data from WRAM' - a read-only memory inspection operation. No modification, deletion, or execution capabilities are indicated.
Attacks that exploit this kind of access
Dump entity/actor data from WRAM - useful for analyzing game objects. It is categorised as a Read tool in the mGBA MCP Server MCP Server, which means it retrieves data without modifying state.
Register the mGBA MCP Server MCP server in PolicyLayer and add a rule for mgba_dump_entities: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches mGBA MCP Server. Nothing to install.
mgba_dump_entities is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mgba_dump_entities rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mgba_dump_entities. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mgba_dump_entities is provided by the mGBA MCP Server MCP server (struktured-labs/mgba-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
