Config

Add this server to your MCP-compatible client using the configuration below.

{
  "mcpServers": {
    "fdp_basic": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "https://fdp.qianxin.com/mcp/v1/basic/mcp/"

Tools

查询 PassiveDNS 中的 flint rrset 数据。 flint rrset 是用于查询特定域名和记录类型的资源记录集（Resource Record Set，简称 RRset）。如果想要查询子域名的 rrset，可以使用通配符形式，比如：*.example.com，就会返回 examle.com 子域名的 flint rrset 记录。

查询 PassiveDNS 中的 flint rdata 数据。通过 rdata 反向查询 DNS 响应的 rrset 中的记录数据。

查询域名的 whois 注册信息

查询某些域名的证书信息

查询威胁指标（IoC）数据库，这些指标可用于检测和应对潜在的安全威胁。

Overview

What is Basic Network Data Query Tool?

A toolset by QiAnXin XLab that provides core network security data queries including PassiveDNS resolution records, historical WHOIS information, digital certificate details, and IOC (Indicators of Compromise) database lookups. It is designed for security researchers and analysts needing network infrastructure intelligence.

How to use Basic Network Data Query Tool?

Connect to the remote MCP service at https://fdp.qianxin.com/mcp/v1/basic/mcp/ using streamable-http transport. For the official version, include the fdp-access and fdp-secret HTTP headers (obtained from QiAnXin XLab). The README shows integration examples with smolagents and Claude Desktop via mcp-remote proxy.

FAQ from Basic Network Data Query Tool

What transport and authentication does Basic Network Data Query Tool use?

It uses streamable-http transport. Authentication requires two HTTP headers: fdp-access and fdp-secret, provided by QiAnXin XLab.

Is there a trial version?

Yes, a trial version is available. Under high-concurrency conditions, the backend may throttle network access. For production-level use, switch to the official version.
