Deep DNS traffic analysis of a locally synced PCAP. Returns: top queried domains, query type distribution (A, AAAA, MX, TXT, etc.), response code breakdown (NOERROR, NXDOMAIN, SERVFAIL), NXDOMAIN domains, DNS client/server IPs, resolved IPs, response time statistics (min/max/avg/median/p95), TTL ...
AI agents call wireshark_dns_analysis 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.
The tool analyzes network traffic captured in PCAP files to extract DNS metrics and statistics (domains, query types, response codes, response times, TTL stats, anomalies). All operations are read-only queries against pre-synced packet data. There is no execution of code, modification of data, deletion, or financial impact.
From the tool's definition Performs 'Deep DNS traffic analysis' and 'Returns: top queried domains, query type distribution, response code breakdown' — this is data retrieval and inspection of existing PCAP files with no modification or execution of external operations.
Attacks that exploit this kind of access
Deep DNS traffic analysis of a locally synced PCAP. Returns: top queried domains, query type distribution (A, AAAA, MX, TXT, etc.), response code breakdown (NOERROR, NXDOMAIN, SERVFAIL), NXDOMAIN domains, DNS client/server IPs, resolved IPs, response time statistics (min/max/avg/median/p95), TTL stats, and anomaly detection (high NXDOMAIN rates, long domain names suggesting tunneling, high subdomain variety, excessive TXT queries, slow resolution). Use after wireshark_pcap_triage flags DNS issues. Sync the PCAP first using wireshark_sync_pcap. Required: pcap_name. 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_dns_analysis: 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_dns_analysis 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_dns_analysis 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_dns_analysis. 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_dns_analysis 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.
