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.
LlamaIndex agents combine Fly.io tool responses with indexed documents for comprehensive, grounded answers. Connect 10 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.
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 LlamaIndex 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 LlamaIndex with the Fly.io MCP Server
LlamaIndex provides unique advantages when paired with Fly.io through the Model Context Protocol.
Data-first architecture: LlamaIndex agents combine Fly.io tool responses with indexed documents for comprehensive, grounded answers
Query pipeline framework lets you chain Fly.io tool calls with transformations, filters, and re-rankers in a typed pipeline
Multi-source reasoning: agents can query Fly.io, a vector store, and a SQL database in a single turn and synthesize results
Observability integrations show exactly what Fly.io tools were called, what data was returned, and how it influenced the final answer
Fly.io + LlamaIndex Use Cases
Practical scenarios where LlamaIndex combined with the Fly.io MCP Server delivers measurable value.
Hybrid search: combine Fly.io real-time data with embedded document indexes for answers that are both current and comprehensive
Data enrichment: query Fly.io to augment indexed data with live information before generating user-facing responses
Knowledge base agents: build agents that maintain and update knowledge bases by periodically querying Fly.io for fresh data
Analytical workflows: chain Fly.io queries with LlamaIndex's data connectors to build multi-source analytical reports
Fly.io MCP Tools for LlamaIndex (10)
These 10 tools become available when you connect Fly.io to LlamaIndex 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 LlamaIndex
Ready-to-use prompts you can give your LlamaIndex agent to start working with Fly.io immediately.
"List all machines in my 'web-api' app"
"Run 'ls -la /app' on machine '918572b0' in app 'web-api'"
"Show me the persistent volumes for 'web-api'"
