AI agents call dd_system_info to retrieve information from Ppdm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves static system information (model, version, serial number, uptime) from a Data Domain storage system. It performs a query/get operation with no side effects, no data modification, no code execution, and no destructive capability. The information returned is factual metadata about the system itself.
From the tool's definition Tool name 'dd_system_info' and description 'Get Data Domain system information — model, version, serial number, and uptime' indicate retrieval of read-only system metadata with no modification or execution capabilities.
Attacks that exploit this kind of access
Get Data Domain system information — model, version, serial number, and uptime. It is categorised as a Read tool in the Ppdm MCP Server, which means it retrieves data without modifying state.
Register the Ppdm MCP server in PolicyLayer and add a rule for dd_system_info: 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 Ppdm. Nothing to install.
dd_system_info 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 dd_system_info 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 dd_system_info. 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.
dd_system_info is provided by the Ppdm MCP server (moodswing9/ppdm-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
