How to Use the Fly.io Extended MCP in Mastra AI

Q: How do I connect the Fly.io Extended MCP Server to a Mastra AI agent?

Install @mastra/mcp and instantiate a new MCPClient pointing to your Vinkius server URL. Call mcpClient.listTools() and spread the returned tools directly into your Mastra agent configuration.

Q: Can I require manual human approval before Mastra AI deletes a Fly.io Extended resource?

Yes, you can configure Mastra's requireToolApproval flag specifically for destructive tools like deletemachine or deleteapp. This prevents the agent from tearing down production infrastructure without explicit SRE confirmation.

Q: Can Mastra AI use Fly.io Extended to clone existing machines?

Your agent can call getmachine to read the configuration of an active microVM, modify the parameters, and then call createmachine to deploy an identical clone. This allows your workflows to scale compute horizontally based on application load.

Automate MicroVM Lifecycles with Mastra AI

`start_machine` boots up dormant Fly.io compute resources whenever your Mastra AI workflow detects an incoming traffic spike. This MCP Server lets your agent execute cold starts programmatically without human intervention. If a machine becomes unresponsive, `stop_machine` terminates the unhealthy instance so your workflow can trigger a replacement. Mastra handles the conditional logic to ensure your application remains highly available.

Scale Disks Programmatically

`create_volume` attaches persistent storage to your microVMs during automated workflow runs. Mastra AI agents use this tool to provision databases in new regions on demand. When disk usage crosses critical thresholds, `extend_volume` increases the capacity of existing drives. The Mastra workflow engine catches any API timeouts and retries the operation automatically with exponential backoff.

Automate SSL Issuance

`create_acme_certificate` requests Let's Encrypt SSL certificates for custom hostnames mapped to your Fly.io apps. Your Mastra AI agent triggers this call as part of a user onboarding workflow. To ensure the certificate is active, `check_certificate` queries the DNS status until validation succeeds. If validation fails, Mastra routes the error to your admin channel for manual review.

Setup guide

Set up Fly.io Extended MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Fly.io Extended tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "flyio-extended-mcp-client",
  servers: {
    "flyio-extended-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Fly.io Extended Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Fly.io Extended tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Fly.io Extended transactions"
);
console.log(result.text);

Common questions about Fly.io Extended MCP in Mastra AI

Install `@mastra/mcp` and instantiate a new `MCPClient` pointing to your Vinkius server URL. Call `mcpClient.listTools()` and spread the returned tools directly into your Mastra agent configuration.

Yes, you can configure Mastra's `requireToolApproval` flag specifically for destructive tools like `delete_machine` or `delete_app`. This prevents the agent from tearing down production infrastructure without explicit SRE confirmation.

Mastra's built-in workflow engine automatically handles API rate limits by queueing calls and executing retries. If `create_machine` hits a temporary Fly.io API limit, the workflow backs off and tries again without failing the overall run.

Your agent can call `get_machine` to read the configuration of an active microVM, modify the parameters, and then call `create_machine` to deploy an identical clone. This allows your workflows to scale compute horizontally based on application load.

Vinkius encrypts your Fly.io deployment credentials at rest and executes all tool calls within ephemeral environments. Your Mastra workflows only receive sanitized execution receipts and machine metadata, keeping your root access keys completely hidden from the agent code.
