What wireshark_dns_analysis does on Wireshark MCP Server

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.

Why wireshark_dns_analysis needs a policy

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.

Questions about wireshark_dns_analysis

What does the wireshark_dns_analysis tool do? +

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.

How do I enforce a policy on wireshark_dns_analysis? +

Can I rate-limit wireshark_dns_analysis? +

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.

How do I block wireshark_dns_analysis completely? +

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.

What MCP server provides wireshark_dns_analysis? +
