AI agents call wireshark_analyze_pcap 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_analyze_pcap is fundamentally a read operation—it queries and extracts information from network packet capture files. While it may reveal sensitive data (credentials in unencrypted protocols, IP addresses, traffic patterns), it does not modify PCAP files, execute code, delete data, or move funds.
From the tool's definition Tool performs 'analysis' and 'returns' data from PCAP files: 'protocol distribution, packet statistics, security findings, flow analysis, and sample packets'. No modification, deletion, or execution of external systems is described.
Attacks that exploit this kind of access
Comprehensive analysis of a locally synced PCAP file. Returns protocol distribution, packet statistics (top talkers, top ports, packet sizes), security findings (port scans, suspicious ports, unencrypted protocols), flow analysis (conversation tracking, significant flows), and sample packets for LLM inspection. Sync the PCAP first using wireshark_sync_pcap. Required: pcap_name. Optional: max_packets (default: 100), focus_protocols (list like [. 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_analyze_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 Wireshark MCP Server. Nothing to install.
wireshark_analyze_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 wireshark_analyze_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 wireshark_analyze_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.
wireshark_analyze_pcap 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.
