AI agents call get_router_list to retrieve information from Sacloud without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'get_router_list' clearly denotes a retrieval/query operation with no side effects. The tool is intended to list routers in the user's Sakura Cloud infrastructure, which is a read-only action. No modification, deletion, or execution of arbitrary operations occurs.
From the tool's definition Tool name 'get_router_list' indicates a retrieval operation; no description provided, but the pattern matches sibling tools (get_archive_list) that are clearly read-only queries. Sakura Cloud router listing is non-destructive enumeration.
Documented attack patterns abuse exactly the kind of access get_router_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sacloud, and nothing reaches the server without passing your rules. This is the rule we recommend for get_router_list:
{
"version": "1",
"default": "deny",
"tools": {
"get_router_list": {}
}
}get_router_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_router_list. It is categorised as a Read tool in the Sacloud MCP Server, which means it retrieves data without modifying state.
Register the Sacloud MCP server in PolicyLayer and add a rule for get_router_list: 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 Sacloud. Nothing to install.
get_router_list 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 get_router_list 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 get_router_list. 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.
get_router_list is provided by the Sacloud MCP server (sacloud/sacloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sacloud, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
