FAQ from NetForensicMCP

What are the runtime dependencies?

Requires Node.js v16+, Wireshark/tshark in PATH, and npm for dependency management. Works on Windows, macOS, and Linux.

How does NetForensicMCP handle large PCAP files?

It uses intelligent chunking with pagination support, content size estimation, and automated stream segmentation to prevent token overflow.

Where does threat intelligence data come from?

Built-in integration with URLhaus (abuse.ch) for comprehensive malware URL database checking.

Does NetForensicMCP support live traffic capture?

Legacy capture_packets tool is preserved for compatibility, but the focus is on offline forensic analysis.

How is the server configured for different MCP clients?

For Cursor IDE, edit mcp.json with the path to index.js. For Claude Desktop, edit the appropriate config file (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json).
