Click on "Deploy 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., "@url-js-finderscan example.com for JS files, subdomains, and sensitive info"
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.
url-js-finder MCP Server
封装两个开源 URL/JS 信息提取工具为 MCP server,供 AI 全局调用(Reasonix [[plugins]] 注册)。
授权提醒:两个工具均为主动网络爬取工具,仅可用于自有或已授权目标(渗透测试、CTF、SRC)。
许可证
封装代码(server.py / SKILL.md / test_client.py 等):MIT,见 LICENSE
上游工具:
third_party/URLFinder(pingc0y/URLFinder,MIT)与third_party/JSFinder(Threezh1/JSFinder),各自 LICENSE 随源码保留。

urlfinder_scan — URLFinder 页面信息提取
扫描单个 URL 或批量 URL 文件,返回:域名列表、主域 URL、其他域 URL、JS 链接、敏感信息、fuzz 结果。
关键参数:url / batch_file(二选一)、status_codes(如 200,403 或 all)、
mode(1 正常 / 2 深入 / 3 安全深入)、domain_regex、cookie、user_agent、proxy、
timeout、threads、max_links、fuzz(1/2/3)、export_dir、run_timeout。
jsfinder_scan — JSFinder JS 提取
扫描页面 URL 或 URL/JS 列表文件,返回:URL 列表、子域名列表。
关键参数:url / file(二选一)、is_js_file、deep(深度爬取)、cookie、run_timeout。
使用注意
授权:两个工具均为主动网络爬取工具,仅可用于自有/已授权目标。
速度:
status_codes验证与deep深度爬取显著耗时;大目标先试mode=1。返回:所有工具返回 JSON 字符串(UTF-8,
ensure_ascii=False),可直接结构化解析。超时:
run_timeout控制整个扫描进程超时,超时返回明确 error 信息。
自测
python test_client.py重新编译 URLFinder(可选)
cd third_party/URLFinder
go build -ldflags "-s -w -X github.com/pingc0y/URLFinder/cmd.Update=dev" -o ../../bin/URLFinder.exe .配置注册(Reasonix config.toml)
