AI agents call wireshark_sync_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_sync_pcap performs a fetch/download operation that retrieves data (PCAP files) from a remote repository to enable analysis. This is a read operation with no side effects on the source data, no irreversible changes, and no code execution. The tool is purely preparatory for analysis workflows.
From the tool's definition Tool description states it "Downloads the specified file from the configured GitHub repo" and "Sync a PCAP file from GitHub to the local workspace for analysis." The operation is retrieval-only with no modification, deletion, or code execution.

Required: pcap_name (filename 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_sync_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_sync_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_sync_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_sync_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_sync_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.
