Can my agent scale up my application by creating more machines in a specific region?

Yes. Use the 'create_machine' tool. You can specify the region (e.g., 'iad', 'gru') and the Docker image. The agent will command the Fly.io orchestrator to boot up new VM instances instantly to handle increased demand.

How do I run a database migration or shell command on a live machine via chat?

Use the 'exec_machine' tool. Provide the machine ID and the command. The agent bypasses SSH entirely by interacting directly with the hypervisor API to run your binary alongside the running container securely.

Can I check the health and image version of my active machines through the agent?

Absolutely. The 'get_machine' tool retrieves exhaustive runtime states, including container health, current executing status (started/stopped), and the precise docker image digest actively booted into memory.

About Fly.io MCP Server

Connect your Fly.io account to any AI agent and take full control of your edge computing and container orchestration through natural conversation.

Claude Desktop is the definitive way to connect Fly.io to your AI workflow. Add the Vinkius Edge URL to your config, restart the app, and Claude immediately exposes all 10 tools in the chat interface — ask a question, Claude calls the right tool, and you see the answer. Zero code, zero context switching.

What you can do

App Space Orchestration — List logical parent containers (Apps) spanning the Fly Edge network, identifying anycast assignments and dedicated IPv4/IPv6 IPs natively
Machine Runtime Management — Navigate and control individual MicroVM (Machine) endpoints, fetching unique IDs and explicit placement regions flawlessly
Autonomous Scaling — Provision new highly available Edge Machines to scale horizontal capacities dynamically without waiting on full platform deployments
Live Health Auditing — Examine exhaustive runtime states, returning dynamic executing statuses (started, stopped, suspended) and docker image digests in real-time
Remote Command Execution — Inject and run shell commands inside active Machines bypassing SSH by interacting directly with the hypervisor API securely
Persistent Storage Control — List hardware NVMe Volumes attached to your apps to manage stateful data like PostgreSQL or SQLite independent of compute
Network DNA Extraction — Retrieve the operational baseline of Fly Apps, identifying Wireguard ranges and cluster master regions synchronously

The Fly.io MCP Server exposes 10 tools through the Vinkius. Connect it to Claude Desktop in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Claude Desktop with the Fly.io MCP Server

Claude Desktop by Anthropic provides unique advantages when paired with Fly.io through the Model Context Protocol.

Claude Desktop is the reference MCP client — it was designed alongside the protocol itself, ensuring the most complete and stable MCP implementation available

Zero-code configuration: add a server URL to a JSON file and Claude instantly discovers and exposes all available tools in the chat interface

Claude's extended thinking capability lets it reason through multi-step tool usage, chaining multiple API calls to answer complex questions

Enterprise-grade security with local config storage — your tokens never leave your machine, and connections go directly to the Vinkius Edge network

Fly.io + Claude Desktop Use Cases

Practical scenarios where Claude Desktop combined with the Fly.io MCP Server delivers measurable value.

Interactive data exploration: ask Claude to query DNS records, look up WHOIS data, and cross-reference results in a single conversation

Ad-hoc security audits: type a domain name and let Claude enumerate subdomains, check DNS history, and flag configuration anomalies — all through natural language

Executive briefings: generate comprehensive domain intelligence reports by asking Claude to compile findings into a formatted summary

Learning and training: new team members can explore API capabilities conversationally without needing to read documentation

Fly.io MCP Tools for Claude Desktop (10)

These 10 tools become available when you connect Fly.io to Claude Desktop via MCP:

create_machine

Scales horizontal capacities dynamically without waiting on full platform deployments. Provision a new highly available Edge Machine inside an App

delete_machine

The Firecracker VM is dropped, compute billing ceases immediately, and any ephemeral disk state dissolves. Fails safely if persistent volumes are explicitly attached without the force flag. Terminate and destroy a Fly Machine forever (Scale Down)

exec_machine

Useful for `ls`, `ps aux`, `top`, or running internal database diagnostic migrations. Inject and run a shell/Bash command inside an active Fly Machine

get_app

Identifies the primary Region holding the cluster master, internal Wireguard network ranges assigned, and any active Anycast IPs actively routing inbound user traffic globally. Retrieve the operational baseline state of a distinct Fly App

get_machine

Returns dynamic executing states ("started", "stopped", "suspended"), the precise docker image digest/SHA actively booted into RAM, and any mapped volume points tying persistent SQLite/Postgres logs. Get exhaustive runtime states attached to a single Fly Machine

list_apps

Apps are fundamentally distinct collections of individual microVMs (Machines), dedicated IPv4/IPv6 anycast assignments, and persistent storage volumes. List Fly.io App spaces belonging to an Organization

list_machines

Retrieves unique identifiers and explicit placement Regions (e.g., iad, ams, nrt). List individual MicroVM (Machine) endpoints inside a Fly App

list_volumes

Crucial identifier for managing stateful applications (PostgreSQL, SQLite, persistent cache) safely independent of compute instances. List persistent hardware NVMe Volumes attached to an App

start_machine

Utilized extensively when recovering paused batch processors or restarting crashed worker nodes dynamically across edge points of presence. Boot a previously stopped or suspended Fly Machine

stop_machine

Drastically reduces latency bills during idle cycles outside typical user ingress bands. Gracefully halt a running Fly.io internal Machine

Example Prompts for Fly.io in Claude Desktop

Fly.io + Claude Desktop FAQ

Common questions about integrating Fly.io MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully — if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL — Claude auto-negotiates the transport protocol.
