Fly.io
Arcade tools designed for LLMs to interact with Fly.io
1.0.2Fly.io toolkit for Arcade lets LLMs manage the full lifecycle of Fly.io applications, machines, volumes, networking, secrets, and certificates via the Fly.io API.
Capabilities
- App & release management: list apps and organizations, inspect app status, view release history, and roll out new container images across all machines.
- Machine lifecycle: create, start, stop, restart, and destroy individual machines; retrieve configuration and health state; scale machine count or change VM size/memory fleet-wide.
- Persistent storage: create, list, extend, and destroy volumes attached to apps.
- Networking & TLS: allocate and release dedicated IP addresses, list assigned IPs, and manage custom-domain certificates (add, check validation status, list, remove) including DNS record guidance.
- Secrets management: set, unset, and list app secret names (values are never exposed by Fly.io); optional immediate rollout on set/unset operations.
- Observability: read recent historical log entries for an app with optional filtering; log access requires a token with explicit log-read permission — the tool returns a
no_accessstatus rather than an error when that permission is absent, so callers should branch onstatus.
Secrets
FLYIO_ACCESS_TOKEN — A Fly.io personal access token or deploy token used to authenticate all API calls. To create one, log in to the Fly.io dashboard and generate a new personal access token, or use the Fly CLI (fly tokens create). If log reading is required, ensure the token is granted log-read access (a distinct capability in Fly.io's token permission model). Deploy tokens scoped to a single app can be created under App → Tokens in the dashboard and are preferred for least-privilege automation.
Store this secret in Arcade using the Arcade secrets guide or directly at https://api.arcade.dev/dashboard/auth/secrets.

| 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 |
