What DescribeDiscoveryDevices does on Ioacloud
AI agents call DescribeDiscoveryDevices to retrieve information from Ioacloud without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why DescribeDiscoveryDevices is rated Low
Even though DescribeDiscoveryDevices 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.

The rule that runs DescribeDiscoveryDevices safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ioacloud, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For DescribeDiscoveryDevices, this is the rule to start with:
DescribeDiscoveryDevices is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ioacloud, apply this rule, and every DescribeDiscoveryDevices call is checked against it from then on.

DescribeDiscoveryDevices accepts 4 parameters: Condition, SourceType, TerminalType, IsClientInstalled. The full parameter table on this page comes from the server's own tool schema.
Register the Ioacloud MCP server in PolicyLayer and add a rule for DescribeDiscoveryDevices: 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 Ioacloud. Nothing to install.
DescribeDiscoveryDevices 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 DescribeDiscoveryDevices 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 DescribeDiscoveryDevices. 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.
DescribeDiscoveryDevices is provided by the Ioacloud MCP server (@ioacloud/ioacloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
