How to Use the CrowdStrike Falcon MCP in Pydantic AI

Q: Can Pydantic AI agents perform CrowdStrike Falcon remediation?

Yes, you can define an agent that uses the containdevice tool. The agent's logic ensures the device ID is valid before execution.

Validated security responses in Pydantic AI

Every response from `list_detections` is validated against your Pydantic models. If the API returns unexpected fields, your agent crashes safely instead of hallucinating data. Use `update_detection` to add triage comments. The tool enforces the structure you expect, ensuring your security logs remain consistent and readable.

Strict device inventory with this MCP Server

Query `search_hosts` to get validated device data directly into your agent's state. The strict typing prevents your agent from attempting to process malformed host info. Call `contain_device` to execute containment commands. Because this is Pydantic AI, the agent validates the device ID format before the command is sent, preventing errors.

Manage custom IOCs within Pydantic AI

The `list_iocs` tool feeds raw indicator data into your agent, which is then mapped to your Pydantic schemas. This ensures your agent only acts on valid IP or hash formats. Use `create_ioc` to push new threat indicators. Your agent validates the input before the call, so you never push a malformed block to your security stack.

Setup guide

Set up CrowdStrike Falcon MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "crowdstrike-falcon-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to CrowdStrike Falcon tools.",
)

result = await agent.run("List recent CrowdStrike Falcon transactions")
print(result.output)
