AI agents call wireshark_top_talkers 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.
This tool reads and queries packet data to produce statistical summaries of network traffic. It has no side effects—it does not modify the PCAP, execute commands, delete data, or trigger external operations. The results are purely informational analysis of existing captured traffic, making it a straightforward Read category tool with low severity.
From the tool's definition The tool description states it 'Identify[s] highest-volume traffic sources' and 'Returns ranked lists' of network statistics.
Attacks that exploit this kind of access
Identify highest-volume traffic sources in a locally synced PCAP. Returns ranked lists of: top source IPs, top destination IPs, top conversations (src->dst pairs), top destination ports, top protocols, and top 5-tuple flows - each with packet count, byte count, and percentage of total. Use to quickly identify what is generating the most traffic. Sync the PCAP first using wireshark_sync_pcap. Required: pcap_name. Optional: top_n (entries per category, default: 15). 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 wireshark_top_talkers: 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.
wireshark_top_talkers 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 wireshark_top_talkers 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 wireshark_top_talkers. 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.
wireshark_top_talkers is provided by the Wireshark MCP Server MCP server (presidio-federal/wireshark-mcp-container). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
