wireshark-mcp-win
Provides tools for interacting with Wireshark's command-line utilities (tshark, dumpcap, capinfos, editcap, mergecap) to perform live packet capture, offline pcap analysis, display filtering, protocol statistics, TCP/UDP stream reassembly, packet/object export, and opening captures in the Wireshark GUI.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@wireshark-mcp-winCapture 10 HTTP packets on Wi-Fi and save to pcapng"
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.
wireshark-mcp-win
基于 Model Context Protocol (MCP) 官方 Python SDK v2 的 Wireshark MCP 服务器(Windows 平台)。将 Wireshark 核心工作流暴露给 AI Agent:实时抓包、离线 pcap 分析、显示过滤器、统计、TCP/UDP 流重组、包导出与 Wireshark GUI 可视化展示。
功能
16 个 MCP 工具,底层封装 tshark / dumpcap / capinfos / editcap / mergecap:
工具 | 功能 |
| 列出可抓包网卡 |
| 实时抓包(限时/限量/BPF 过滤器),存 pcapng |
| 读 pcap:显示过滤、字段提取、text/fields/json/hex 输出、翻页、强制解码、TLS 密钥解密 |
| 查询协议字段表(进程内缓存) |
| 校验显示过滤器语法 |
| 列出 TCP/UDP 流,含端点、包数与字节数摘要 |
| 流重组(ascii/hex,支持显示过滤器限定范围) |
| 统计:io / conv / endpoints / phs / http / http_req / expert / hosts / ip_hosts / dns / sip |
| pcap 文件元信息(capinfos) |
| 多文件合并(mergecap) |
| 编辑:时间截取 / 分块 / 截断 / 去重(editcap) |
| 强制协议解码(tshark -d) |
| 在 Wireshark GUI 中打开 pcap(预置过滤器/跳转包号) |
| 启动 Wireshark GUI 实时抓包展示 |
| 导出:pcapng/pcap/csv/json/pdml/psml/ek/text |
| 导出协议对象(http/smb/tftp/icmp/imf 嵌入式文件) |
资源:wireshark://version、wireshark://interfaces、wireshark://file/{path}
提示模板:analyze_general / analyze_http / analyze_tls / analyze_dns / analyze_tcp
设计要点:
上下文安全:返回结果自动截断(默认 200 KB),大导出落盘只回传摘要与路径
路径白名单:写入类操作(抓包/导出/合并/编辑)限定在工作目录内;读取支持任意路径
性能优化:无过滤器单趟快速路径、翻页范围式过滤、过滤器校验缓存、字段表进程内缓存

环境要求
Windows 10/11(本机已验证 Windows 11)
已安装 Wireshark(含 tshark/dumpcap/capinfos/editcap/mergecap 与 Npcap 驱动)
Python 3.10+(开发环境 3.13)
安装
python -m venv .venv
.venv\Scripts\pip install -r requirements.txt启动
# stdio(默认,供 MCP 客户端拉起,如 opencode)
.venv\Scripts\python server.py
# Streamable HTTP 服务
.venv\Scripts\python server.py --transport streamable-http --host 127.0.0.1 --port 8000
# 客户端连接 http://127.0.0.1:8000/mcp
# SSE(旧版 HTTP 传输,兼容老客户端)
.venv\Scripts\python server.py --transport sse --port 8000常用参数(--help 查看全部):
参数 | 说明 | 默认值 |
| Wireshark 安装目录(缺省自动发现:注册表/PATH/常见路径) | 自动 |
| 抓包输出目录 |
|
| 导出文件目录 |
|
| 单次返回给模型的结果上限,防上下文爆炸 | 200000 |
| 调试日志 | 关 |
MCP 客户端配置
opencode(opencode.json)
{
"mcp": {
"wireshark-mcp-win": {
"type": "local",
"command": [
"D:\\path\\to\\wireshark-mcp-win\\.venv\\Scripts\\python.exe",
"D:\\path\\to\\wireshark-mcp-win\\server.py"
],
"enabled": true
}
}
}注意事项
抓包权限:实时抓包(
capture_packets/live_display_capture)依赖 Npcap 驱动,非提权进程能否抓包取决于 Npcap 安装时的 ACL 设置(默认仅限管理员)。抓包报权限错误时,请以管理员身份运行本服务。TLS 解密:
read_packets(keylog_file="...")传入 SSLKEYLOGFILE 即可解密 HTTPS 流量。大文件处理:先用
edit_pcap(去重/分块/时间截取)预处理,或用read_packets(limit=..., offset=...)翻页分析。
