AI agents call describe_vswitches to retrieve information from Alibaba Cloud RDS OpenAPI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite the empty description limiting confidence slightly, the naming convention is clear: 'describe_' prefixed tools in cloud management APIs universally perform read-only queries without side effects. VSwitch information retrieval poses minimal risk even if misused by an agent—it returns network topology data but cannot modify or delete resources.
From the tool's definition Tool name 'describe_vswitches' indicates a query/description operation that retrieves information about virtual switches (network infrastructure) in Alibaba Cloud.
Documented attack patterns abuse exactly the kind of access describe_vswitches gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Alibaba Cloud RDS OpenAPI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for describe_vswitches:
{
"version": "1",
"default": "deny",
"tools": {
"describe_vswitches": {}
}
}describe_vswitches is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

describe_vswitches. It is categorised as a Read tool in the Alibaba Cloud RDS OpenAPI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Alibaba Cloud RDS OpenAPI MCP Server MCP server in PolicyLayer and add a rule for describe_vswitches: 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 Alibaba Cloud RDS OpenAPI MCP Server. Nothing to install.
describe_vswitches 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 describe_vswitches 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 describe_vswitches. 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.
describe_vswitches is provided by the Alibaba Cloud RDS OpenAPI MCP Server MCP server (aliyun/alibabacloud-rds-openapi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
