List all supported gaming systems/consoles you can search ROMs for.
AI agents call list_systems to retrieve information from Romulus 31780 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though list_systems only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access list_systems gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Romulus 31780, and nothing reaches the server without passing your rules. This is the rule we recommend for list_systems:
{
"version": "1",
"default": "deny",
"tools": {
"list_systems": {}
}
}list_systems is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all supported gaming systems/consoles you can search ROMs for. It is categorised as a Read tool in the Romulus 31780 MCP Server, which means it retrieves data without modifying state.
Register the Romulus 31780 MCP server in PolicyLayer and add a rule for list_systems: 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 Romulus 31780. Nothing to install.
list_systems 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 list_systems 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 list_systems. 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.
list_systems is provided by the Romulus 31780 MCP server (openclaw-hal9000/romulus-31780). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
