Get a high-level summary of a pcap file: I/O stats, protocol
AI agents call summarize_pcap to retrieve information from Mcp Wireshark without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only summarizes and analyzes existing packet capture data. It has no side effects—it does not modify network state, execute code, delete files, or trigger financial transactions. The summarization and statistical analysis of pcap files is a passive read operation similar to inspecting logs or querying a database for information.
From the tool's definition Tool performs read-only analysis: 'Get a high-level summary of a pcap file: I/O stats, protocol'. It retrieves and queries network traffic data without modifying, deleting, or executing external operations.
Documented attack patterns abuse exactly the kind of access summarize_pcap gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Wireshark, and nothing reaches the server without passing your rules. This is the rule we recommend for summarize_pcap:
{
"version": "1",
"default": "deny",
"tools": {
"summarize_pcap": {}
}
}summarize_pcap is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a high-level summary of a pcap file: I/O stats, protocol. It is categorised as a Read tool in the Mcp Wireshark MCP Server, which means it retrieves data without modifying state.
Register the Mcp Wireshark MCP server in PolicyLayer and add a rule for summarize_pcap: 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 Mcp Wireshark. Nothing to install.
summarize_pcap 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 summarize_pcap 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 summarize_pcap. 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.
summarize_pcap is provided by the Mcp Wireshark MCP server (khuynh22/mcp-wireshark). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Wireshark, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
