Which integrations are available for this server?

Provides tools for analyzing PCAP files using Wireshark's tshark and capinfos, enabling network troubleshooting and packet analysis.

How do I use PacketMaster?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@PacketMaster run a quick network scan on the pcap at /tmp/capture.pcap" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

PacketMaster

MCP server for network-troubleshooting PCAP analysis via tshark. Pairs with Cursor skills pcap-troubleshooting (domain workflows) and packetmaster-mcp (MCP tool usage).

Prerequisites

Python 3.10+
uv (recommended) or pip
Wireshark with CLI tools: tshark, capinfos

brew install wireshark   # macOS

PacketMaster auto-detects `/Applications/Wireshark.app/Contents/MacOS/tshark` if not on PATH.

Related MCP server: Wireshark MCP

Install

cd "/Users/networkze/Documents/Claude Projects/PacketMaster"
uv sync --extra dev

Cursor MCP Configuration

Install the launcher (once), then add to ~/.cursor/mcp.json:

mkdir -p ~/.packetmaster-mcp
cp scripts/start-mcp.sh ~/.packetmaster-mcp/start-mcp.sh
chmod +x ~/.packetmaster-mcp/start-mcp.sh

{
  "mcpServers": {
    "packetmaster": {
      "command": "/Users/networkze/.packetmaster-mcp/start-mcp.sh",
      "env": {
        "FASTMCP_SHOW_SERVER_BANNER": "false"
      }
    }
  }
}

Uses a launcher script (like flipper-zero) because Cursor can break uv run paths that contain spaces.

PCAP paths must be absolute. By default any readable .pcap on disk is allowed. Set PM_ALLOWED_DIRS only if you want an opt-in sandbox.

Environment Variables

Variable	Default	Description
`PM_ALLOWED_DIRS`	(unset)	Optional colon-separated allowlist; when set, paths must stay inside
`PM_REQUIRE_ALLOWED_DIRS`	false	If true, `PM_ALLOWED_DIRS` must be set or startup validation fails
`PM_MAX_FILE_SIZE`	10GB	Max PCAP file size
`PM_MAX_PACKETS`	10000	Max packets per extraction request
`PM_MAX_STDOUT_BYTES`	10MB	Max subprocess stdout
`PM_TIMEOUT`	300	Subprocess timeout (seconds)
`PM_HASH_MAX_BYTES`	500MB	Skip SHA-256 above this size unless requested
`PM_REDACT_SENSITIVE`	true	Redact credentials in stream/field output
`TSHARK_PATH`	auto	Override tshark binary path

Tools

Tool	Description
`pm_check_install`	Verify tshark/capinfos installation
`pm_file_info`	capinfos + optional SHA-256
`pm_protocol_hierarchy`	Protocol distribution
`pm_conversations`	Top conversations by bytes
`pm_endpoints`	Top IP endpoints
`pm_expert_info`	Wireshark expert information
`pm_tcp_anomalies`	TCP retrans/dup ACK/zero window/OOO/RST
`pm_latency_summary`	Per-flow RTT statistics
`pm_io_stats`	Traffic over time
`pm_extract_fields`	Paginated field extraction
`pm_follow_stream`	Follow TCP/UDP/HTTP/TLS stream (redacted)
`pm_filter_packets`	Packet summaries by display filter
`pm_detect_capture_type`	Start here — wlan vs ethernet + tool routing
`pm_wired_quick_scan`	EPC/SPAN — DHCP, DNS, ICMP, VLAN, L2 infra, TCP
`pm_dhcp_analysis`	DHCP phases, stuck patterns, optional MAC filter
`pm_dns_analysis`	DNS queries/responses, NXDOMAIN, top names
`pm_asymmetric_hints`	One-sided capture / path asymmetry heuristics
`pm_troubleshoot_quick_scan`	L3 TCP-focused composite (alternate to wired scan)
`pm_troubleshoot_flow`	Deep dive between two IPs
`pm_wifi_quick_scan`	802.11 monitor — retries, mgmt, roaming, BSSIDs
`pm_wifi_client_analysis`	Deep dive on one STA by MAC
`pm_wifi_roaming_analysis`	802.11k/v roam timeline for one STA

Workflow with NetOps EPC

Capture via ios_xe_epc_capture_run (user-netops MCP) with pull_pcap=true
Run pm_troubleshoot_quick_scan on the returned local_path
Drill down with pm_troubleshoot_flow on suspect IPs

Development

uv run pytest -q
uv run packetmaster-mcp   # stdio MCP server

Security

PCAP paths must be absolute; optional PM_ALLOWED_DIRS sandbox for locked-down setups
Symlinks rejected
Stream/field output redacts Authorization, Bearer tokens, passwords by default
Confirm with user before pm_follow_stream on production captures
