Fly.io
Arcade tools designed for LLMs to interact with Fly.io
1.0.1Fly.io Toolkit
Arcade toolkit that lets LLMs manage Fly.io infrastructure — apps, Machines, volumes, networking, secrets, TLS certificates, and deployments — via the Fly.io API.
Capabilities
- App & deployment management: List, inspect, and deploy apps across organizations; view release history and scale VM count or size.
- Machine lifecycle: Create, start, stop, restart, and destroy individual Machines; retrieve configuration, state, and health.
- Storage & volumes: Create, extend, list, and destroy persistent volumes attached to apps.
- Networking & TLS: Allocate and release dedicated IP addresses; add, check, and remove custom-domain TLS certificates with DNS record guidance.
- Secrets management: Set, list (names only), and unset app secrets with optional immediate rollout; secret values are never returned by Fly.io.
- Observability: Read recent app logs with optional filtering; note that log access requires a token with explicit log-read permission — tools return a
no_accessstatus rather than an error when that permission is absent.
Secrets
FLYIO_ACCESS_TOKEN — A Fly.io personal access token (or deploy token) used to authenticate every API call. Tokens are created in the Fly.io dashboard under Access Tokens or via flyctl tokens create on the CLI. For full toolkit functionality — including log access — the token must be granted both app-management and log-read permissions; a token lacking log-read will cause Flyio.GetLogs to return no_access. To scope a token to a specific app or organization, use flyctl tokens create deploy -a <app> or the equivalent org-scoped variant. See Fly.io token documentation for details on token types and permission scopes.
Store the token as an Arcade secret: https://docs.arcade.dev/en/guides/create-tools/tool-basics/create-tool-secrets (manage secrets 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 |
