How to Use the CrowdStrike Falcon MCP in LangChain

Q: How do I filter CrowdStrike Falcon detections in LangChain?

Use the listdetections tool with FQL syntax. Pass your filter string directly into the tool arguments within your agent's chain.

Q: Can LangChain automate CrowdStrike Falcon host isolation?

Yes, by calling containdevice. You define the host ID in your chain logic, and the agent executes the containment command.

Q: Does this MCP server expose CrowdStrike Falcon vulnerabilities to LangChain?

It provides listvulnerabilities for querying Spotlight data. You can pipe these results into a LangChain agent to prioritize patching tasks.

Chain CrowdStrike Falcon detection logic directly into your LangChain reasoning pipelines for automated security response.

Automate threat containment in LangChain

Trigger `contain_device` based on detection severity without human intervention. Your agent parses the alert and decides if the host needs immediate isolation. This workflow ties detection outputs to defensive actions. The chain ensures that response logic triggers only when specific MITRE ATT&CK criteria are met.

Query security incidents within LangChain

Feed `list_incidents` output into your agent to summarize active threats. You get clear context on who is assigned to each ticket and the current incident state. Your pipeline handles the FQL filtering for you. It pulls the data and maps incident status directly into your decision-making nodes.

Manage custom IOCs in LangChain

Push new threat intelligence into your environment by executing `create_ioc` through a chain. You can define sha256 hashes or domain blocks based on external feeds. This MCP server makes it easy to update your blocklist in real time. The agent handles the tool call as part of a larger security update loop.

Setup guide

Set up CrowdStrike Falcon MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes CrowdStrike Falcon tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "crowdstrike-falcon-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent CrowdStrike Falcon transactions"
    })
    print(result["messages"][-1].content)
