How to Use the Hetzner MCP in CrewAI

Q: How do I assign Hetzner tools to specific CrewAI agents?

Install crewaitools. Use MCPServerHTTP from crewai.mcp and apply a toolfilter so your security agent only sees firewall commands.

Deploy autonomous CrewAI teams that manage, scale, and secure your Hetzner infrastructure.

Perplexity

Scale hardware autonomously

The `list_servers` tool feeds your monitoring agents real-time data about your fleet. You assign one agent to watch system load, and when it detects a bottleneck, it signals a provisioning agent to execute `create_server`. The provisioning agent checks `list_server_types` to find the cheapest available hardware. It spins up the instance, grabs the new IP, and passes the details back to the monitor. Nobody touches a keyboard.

CrewAI agents running the Hetzner MCP Server

The `list_firewalls` tool allows a dedicated security agent to audit your network rules continuously. It scans for open SSH ports and flags any configuration that violates your baseline. If the agent finds a vulnerability, it immediately calls `create_firewall` to apply a strict lockdown policy. You can also have it cycle credentials by generating new keys with `create_ssh_key` and deploying them across the cluster.

Manage certificates and DNS

The `list_certificates` tool lets your operations crew handle SSL renewals before they expire. An agent checks the expiration dates, generates new certs, and uploads them using `create_certificate`. You can pair this with `create_zone` to manage your DNS records autonomously. The CrewAI framework shares memory between agents, so the DNS agent knows exactly which new IPs the provisioning agent just created.

Setup guide

Set up Hetzner MCP in CrewAI

Prerequisites

Python 3.10+ installed
crewai package (pip install crewai)
Active Vinkius subscription with a valid endpoint token

1

Install CrewAI
Run pip install crewai to install the framework. MCP support is built-in via the mcps parameter.
2

Add the MCP URL to your agent
Pass your Vinkius endpoint directly to the mcps list. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. CrewAI handles tool discovery and caching automatically.
3

Kick off your crew
Create a Crew with your agent and tasks. Call crew.kickoff() — the agent will automatically invoke Hetzner tools as needed.

crew.py

from crewai import Agent, Task, Crew

agent = Agent(
    role="Hetzner Analyst",
    goal="Access and analyze Hetzner data via MCP.",
    backstory="Expert analyst with direct Hetzner access.",
    mcps=[
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ],
)

task = Task(
    description="List recent Hetzner transactions",
    agent=agent,
    expected_output="A summary of recent activity",
)

crew = Crew(agents=[agent], tasks=[task])
result = crew.kickoff()
print(result)

Prerequisites

Python 3.10+ installed
crewai + crewai-tools packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install crewai crewai-tools. The MCPServerAdapter handles lifecycle management and tool conversion.
2

Connect with MCPServerAdapter
Use MCPServerAdapter as a context manager with SseServerParameters pointing to your Vinkius endpoint. The adapter automatically manages connection lifecycle.
3

Assign tools and run
Pass the returned mcp_tools to your agent's tools parameter. The adapter converts MCP tools to native BaseTool objects compatible with all CrewAI agents.

crew.py

from crewai import Agent, Task, Crew
from crewai_tools import MCPServerAdapter
from mcp import SseServerParameters

server_params = SseServerParameters(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

with MCPServerAdapter(server_params) as mcp_tools:
    agent = Agent(
        role="Hetzner Analyst",
        goal="Access and analyze Hetzner data via MCP.",
        backstory="Expert analyst with direct Hetzner access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Hetzner transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

    crew = Crew(agents=[agent], tasks=[task])
    result = crew.kickoff()
    print(result)

Common questions about Hetzner MCP in CrewAI

Install crewai[tools]. Use MCPServerHTTP from crewai.mcp and apply a tool_filter so your security agent only sees firewall commands.

Yes. You write a response protocol that triggers the rebuild command. The agent wipes the infected instance and restores it from a clean image.

They do. When Agent A creates a load balancer, Agent B can read that balancer's ID from the shared context and attach servers to it.

Pass your server URL directly into the agent's mcps array. CrewAI negotiates the connection and maps the remote functions into local Python methods.

Never. The integration reads storage box credentials and SSL certificates directly into the agent's context window. Vinkius isolates the execution environment and burns it down after use.
