AI agents call analyze_pcap_file to retrieve information from Wireshark MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Wireshark analysis tools primarily read and interpret captured network packets without modifying them. While the description is empty (lowering confidence slightly), the tool name and server context strongly indicate this performs packet analysis rather than capture, modification, or deletion.
From the tool's definition Tool name 'analyze_pcap_file' combined with server context (Wireshark network analysis) indicates packet capture file analysis.
Documented attack patterns abuse exactly the kind of access analyze_pcap_file gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Wireshark MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_pcap_file:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_pcap_file": {}
}
}analyze_pcap_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
analyze_pcap_file. It is categorised as a Read tool in the Wireshark MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wireshark MCP Server MCP server in PolicyLayer and add a rule for analyze_pcap_file: 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 Wireshark MCP Server. Nothing to install.
analyze_pcap_file 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 analyze_pcap_file 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 analyze_pcap_file. 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.
analyze_pcap_file is provided by the Wireshark MCP Server MCP server (mixelpixx/wireshark-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Wireshark MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
