AI agents call romm_stats to retrieve information from Mcp Romm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns read-only statistical information about a ROM library. It performs no side effects, creates no data, executes no commands, and makes no destructive or financial transactions. It is a straightforward retrieval operation.
From the tool's definition Tool description states 'Get library statistics' — retrieves aggregated data (platform count, ROM count, saves, total size) with no modification capability.
Attacks that exploit this kind of access
Get library statistics — platform count, ROM count, saves, total size. It is categorised as a Read tool in the Mcp Romm MCP Server, which means it retrieves data without modifying state.
Register the Mcp Romm MCP server in PolicyLayer and add a rule for romm_stats: 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 Mcp Romm. Nothing to install.
romm_stats 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 romm_stats 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 romm_stats. 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.
romm_stats is provided by the Mcp Romm MCP server (lodordev/mcp-romm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
