Why pcap_get_conversations needs a policy

This tool passively reads and parses already-captured PCAP files to extract network flow information. It performs forensic analysis (query and retrieval) without side effects, state changes, or external operations. The context of a Windows Forensics MCP Server confirms this is investigative/analytical work.

From the tool's definition Tool name 'pcap_get_conversations' and description 'Extract network conversations (TCP/UDP flows) from PCAP' indicate retrieval and analysis of existing packet capture data. No modification, deletion, or command execution occurs.

POLICY

How to control pcap_get_conversations

PolicyLayer is an MCP gateway — it sits between your AI agents and Windows Forensics MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for pcap_get_conversations:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "pcap_get_conversations": {}
  }
}

pcap_get_conversations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Windows Forensics MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
