Detect wlan vs ethernet capture and recommend entry-point tool.
AI agents call pm_detect_capture_type 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 information from PCAP files to determine network capture type—a read-only operation with no side effects. It does not modify data, execute commands, or trigger external operations. The blast radius if misused is minimal; an AI agent cannot cause damage by detecting capture types. This is a benign informational/diagnostic capability.
From the tool's definition Tool detects and analyzes PCAP file metadata to identify capture type (wlan vs ethernet) and recommend analysis entry points.
Attacks that exploit this kind of access
Detect wlan vs ethernet capture and recommend entry-point tool. 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_detect_capture_type: 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_detect_capture_type 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_detect_capture_type 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_detect_capture_type. 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_detect_capture_type 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.
