Traffic volume over time intervals.
AI agents call pm_io_stats to retrieve information from PacketMaster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes packet capture statistics (input/output traffic metrics over time intervals) from already-captured network data. It performs read-only querying of PCAP file contents to compute and return traffic volume analytics. No side effects, data modification, code execution, or destructive operations are possible.
From the tool's definition Tool name 'pm_io_stats' and description 'Traffic volume over time intervals' indicate passive retrieval of statistical metrics from PCAP files. The server is explicitly designed for 'analysis' and 'troubleshooting' rather than modification.
Attacks that exploit this kind of access
Traffic volume over time intervals. It is categorised as a Read tool in the PacketMaster MCP Server, which means it retrieves data without modifying state.
Register the PacketMaster MCP server in PolicyLayer and add a rule for pm_io_stats: 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 PacketMaster. Nothing to install.
pm_io_stats 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 pm_io_stats 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 pm_io_stats. 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.
pm_io_stats is provided by the PacketMaster MCP server (jctechbr/packetmaster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
