Fly.io
Arcade tools designed for LLMs to interact with Fly.io
1.0.2Fly.io toolkit for Arcade enables LLMs to fully manage Fly.io infrastructure — apps, Machines, volumes, networking, TLS, secrets, and deployments — via the Fly.io API.
Capabilities
- App lifecycle & deployment: list, inspect, and deploy apps by rolling new container images across all Machines; view release history and organization scope.
- Machine management: create, start, stop, restart, and permanently destroy Machines; scale Machine count up or down; resize VM CPU/memory class.
- Storage & volumes: create, extend, list, and destroy persistent volumes attached to apps (volumes can be grown but not shrunk).
- Networking & TLS: allocate and release dedicated IP addresses; add, check, list, and remove custom-domain TLS certificates with DNS record guidance.
- Secrets management: set, unset, and list app secret names (Fly.io never exposes secret values); supports immediate or deferred rollout on changes.
- Observability & metadata: read recent app logs (requires log-read access on the token; returns
no_accessstatus gracefully when missing); list regions, organizations, and IP addresses.
Secrets
FLYIO_ACCESS_TOKEN — A Fly.io personal access token or deploy token used to authenticate every API call. Obtain it from the Fly.io access tokens dashboard by clicking Create token. For production or CI use, prefer a scoped deploy token created with fly tokens create deploy -a <app-name> (requires the Fly CLI); this limits the token to a single app. To read logs via Flyio.GetLogs, the token must additionally have log-read access — create it with fly tokens create readonly or grant log access explicitly, as a standard deploy token does not include it. Store the resulting token string as the secret value.
See the Arcade secrets guide for how to register secrets, or add them directly at https://api.arcade.dev/dashboard/auth/secrets.
Available tools(30)
| Tool name | Description | Secrets | |
|---|---|---|---|
Add a TLS certificate for a hostname and return the DNS records to set. | 1 | ||
Allocate a new IP address for an app. | 1 | ||
Check a certificate's validation status and any pending DNS records. | 1 | ||
Create a new Machine for an app from a container image. | 1 | ||
Create a new persistent volume for an app. | 1 | ||
Roll a new container image out to all of an app's Machines. | 1 | ||
Permanently destroy a Machine. Stop it first unless force is set. | 1 | ||
Permanently destroy a volume and the data it holds. | 1 | ||
Grow a volume to a larger size. Volumes cannot be shrunk. | 1 | ||
Get the current status of a single Fly.io app. | 1 | ||
Read recent historical log entries for an app, optionally filtered.
Reading logs requires a token granted log-read access, which is a capability
separate from app management; a token without it cannot read logs at all. When
that access is missing this returns a ``no_access`` result rather than raising,
so prefer branching on the result's ``status`` over assuming logs are present. | 1 | ||
Get the configuration, state, and health of a single Machine. | 1 | ||
List Fly.io apps, optionally scoped to a single organization.
Apps are returned in Fly.io's own ordering, with pagination metadata so a
caller can tell when more apps exist beyond the returned window. | 1 | ||
List the custom-domain TLS certificates configured on an app. | 1 | ||
List the IP addresses assigned to an app, including the shared IPv4. | 1 | ||
List the Machines that belong to an app. | 1 | ||
List the Fly.io organizations the configured token can access. | 1 | ||
List the Fly.io regions available for deploying apps and volumes. | 1 | ||
List an app's release history, newest first. | 1 | ||
List an app's secret names. Secret values are never returned by Fly.io. | 1 | ||
List the persistent volumes that belong to an app. | 1 | ||
Release a dedicated IP address so it is no longer assigned to the app. | 1 | ||
Remove a custom-domain TLS certificate from an app. | 1 | ||
Restart a Machine and report its settled state. | 1 | ||
Scale an app to a target Machine count by adding or removing Machines. | 1 |
