中文说明：.

QiAnXin XLab provides MCP tools for accessing foundational network security data.

About XLab

XLab is a research team under QiAnXin dedicated to large-scale network security research, threat analysis and attribution, and the construction of multidimensional security data platforms.

XLab is one of the earliest teams in China to leverage large-scale data for cybersecurity research, security applications, and threat intelligence generation. It built the country’s first PassiveDNS system, along with several industry-leading foundational data systems covering NetFlow, Whois, digital certificates, IPs, and malware samples.

Execution Methods

Overview

This application functions as a proxy that translates remote MCP tool calls into local Stdio-based interactions. Therefore, tools can be used either locally or by directly accessing the remote MCP server via its URL.
The remote MCP server currently supports only streamable HTTP access.
This toolset is a trial version intended for basic use. Under high concurrency, the backend may restrict access frequency. For production or high-frequency scenarios, please use the official version.
For official access, use the corresponding tool URL and include two HTTP headers: fdp-access and fdp-secret.
- To obtain credentials, please contact QiAnXin XLab.
The following examples are based on the Basic Network Security Data Query tool.

Trial Version Usage

Run Locally from Source Code

Clone the repository.

Use uv to run and configure Claude Desktop:

{
    "mcpServers": {
        "fdp-mcp-server": {
            "command": "uv",
            "args": [
                "run",
                "--project",
                "/PATH/TO/fdp-mcp-server",
                "fdp-mcp-server",
                "--url",
                "https://fdp.qianxin.com/mcp/v1/basic/mcp/"
            ]
        }
    }
}

Run with Docker

Clone the repository.
Build the Docker image: docker build . fdp-mcp-server:vxx.xx.xx

Configure Claude Desktop:

{
    "mcpServers": {
        "fdp-mcp-server": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "fdp-mcp-server:vxx.xx.xx"
            ]
        }
    }
}

Run via PyPI Package

Use uvx and configure Claude Desktop as follows:

    {
    "mcpServers": {
        "fdp-mcp-server": {
            "command": "uvx",
            "args": [
                "fdp-mcp-server",
                "--url",
                "https://fdp.qianxin.com/mcp/v1/basic/mcp/"
            ]
        }
    }
}

Official Version Usage

If you want to call the fdp-mcp-server tools from within an intelligent agent application, you can configure the remote MCP server URL on the client side and include the required HTTP headers fdp-access and fdp-secret.

When writing agent code, add the headers when calling the MCP tools. Example using smolagents:

from smolagents import ToolCollection
from smolagents.agents import ToolCallingAgent
from smolagents.models import OpenAIServerModel


def main():
    with ToolCollection.from_mcp(
        {
            "url": "https://fdp.qianxin.com/mcp/v1/domain/mcp/",
            "transport": "streamable-http",
            "headers": {
                "fdp-access": "xxxx",
                "fdp-secret": "yyyy",
            },
        },
        trust_remote_code=True,
    ) as tools:
        agent = ToolCallingAgent(
            tools=[*tools.tools],
            model=OpenAIServerModel(
                model_id="YOUR-LLM-MODEL-ID",
                api_base="YOUR-LLM-MODEL-API-URL",
                api_key="YOUR-LLM-MODEL-API-KEY",
            ),
        )
        agent.run("Query the domains associated with www.example.com and assess its likely business purpose based on the associated data.")


if __name__ == "__main__":
    main()

If using Claude Desktop, you can use the mcp-remote library for proxy forwarding and configure the HTTP headers during the process:

{
    "mcpServers": {
        "fdp_domain": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-remote@latest",
                "https://fdp.qianxin.com/mcp/v1/domain/mcp/",
                "--header",
                "fdp-access:xxxx",
                "--header",
                "fdp-secret:yyyy"
            ],
        }
    }
}
