How to Use the Fly.io Extended MCP in CrewAI

Q: How do I add the Fly.io Extended MCP Server to my CrewAI agents?

Pass your Vinkius server URL directly into the mcps list when initializing your CrewAI agents. For advanced setups, import MCPServerHTTP from crewai.mcp and use a tool filter to restrict which agents can execute destructive actions.

Q: Can a CrewAI agent monitor SSL certificates using Fly.io Extended?

Absolutely, your security agent can call listcertificates to audit your domains, and then use checkcertificate to confirm validation status. If a certificate is missing, the agent can call createacmecertificate to resolve the issue.

Deploy a team of autonomous SRE agents to manage your Fly.io Extended infrastructure using CrewAI.

Provision Apps and Compute in Teams

`create_app` registers new application namespaces on the Fly.io platform. Within a CrewAI team, a developer agent can request a new environment, prompting the SRE agent to execute this tool. Once the app exists, `create_machine` deploys the actual microVMs running your containerized code. The crew coordinates these steps, passing the newly generated app name from one agent to the next.

Manage Volumes via CrewAI Multi-Agent Crews

`list_volumes` scans your active Fly.io applications to audit disk usage across all regions. This MCP Server allows your crew to identify orphaned or over-provisioned storage. If an active volume is running out of space, `extend_volume` increases its size automatically. The SRE agent executes the expansion while a coordinator agent logs the change to your team's tracking system.

Recover Unhealthy Machines Autonomously

`list_machines` fetches the operational status of all microVMs running in a specific Fly.io app. Your CrewAI monitoring agent parses this data to detect crashed or unresponsive instances. When a failure is detected, `update_machine` or `start_machine` is called by the recovery agent to reboot the VM. This multi-agent collaboration resolves infrastructure outages without requiring human SRE intervention.

Setup guide

Set up Fly.io Extended 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 Fly.io Extended tools as needed.

crew.py

from crewai import Agent, Task, Crew

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

task = Task(
    description="List recent Fly.io Extended 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="Fly.io Extended Analyst",
        goal="Access and analyze Fly.io Extended data via MCP.",
        backstory="Expert analyst with direct Fly.io Extended access.",
        tools=mcp_tools,
    )

    task = Task(
        description="List recent Fly.io Extended transactions",
        agent=agent,
        expected_output="A summary of recent activity",
    )

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

Common questions about Fly.io Extended MCP in CrewAI

Pass your Vinkius server URL directly into the `mcps` list when initializing your CrewAI agents. For advanced setups, import `MCPServerHTTP` from `crewai.mcp` and use a tool filter to restrict which agents can execute destructive actions.

Yes, your planner agent can design the deployment sequence, while the operator agent calls `create_volume` and `create_machine` in order. They share memory to ensure the volume is fully provisioned before the machine attempts to mount it.

You should configure hard execution limits and token caps on your CrewAI agents. This prevents a misbehaving agent from calling `create_machine` repeatedly in an infinite loop and running up your Fly.io bill.

Absolutely, your security agent can call `list_certificates` to audit your domains, and then use `check_certificate` to confirm validation status. If a certificate is missing, the agent can call `create_acme_certificate` to resolve the issue.

Your Fly.io infrastructure metadata and access keys are shielded behind a secure token exchange layer managed entirely by Vinkius. CrewAI agents never interact with your raw credentials, receiving only the standard JSON payloads returned by the active tools.
