Wireshark expert information (errors, warnings, notes, chats).
AI agents call pm_expert_info 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 queries and returns analytical information from PCAP files. It retrieves expert-level diagnostic insights (errors, warnings, notes) generated by Wireshark analysis without modifying captured data, executing code, or triggering external operations. The output is informational and read-only, making it a Read category tool with low severity.
From the tool's definition pm_expert_info provides 'Wireshark expert information (errors, warnings, notes, chats)' from PCAP analysis—a retrieval of diagnostic metadata from already-captured network data with no modifications or side effects.
Attacks that exploit this kind of access
Wireshark expert information (errors, warnings, notes, chats). 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_expert_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 PacketMaster. Nothing to install.
pm_expert_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 pm_expert_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 pm_expert_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.
pm_expert_info 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.
