Fly.io Machines MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Fly.io Machines and the rest of your systems. It gives your agent 99 Fly.io Machines actions (43 reads, 38 writes and 18 that wait for a confirmation) and holds the Fly.io Machines credential itself, so the agent never does. It paces Fly.io Machines's limits and records every call.

Set up

Connect Fly.io Machines in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

  2. 02

    Connect Fly.io Machines.

    Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Capabilities

What an AI agent can do in Fly.io Machines.

99 actions in 12 areas. Every one carries its effect, so a key can allow the reads and hold the rest.

Top actions

The Fly.io Machines API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 35 of Fly.io Machines's 35 action names are shared with at least one other connector, so an agent learns them once.

Governance for Fly.io Machines

Destructive actions wait for a yes.

18 Fly.io Machines actions are destructive. These are all of them:

  • Destroy a machinefly_io_machines.machines.delete
  • Delete an appfly_io_machines.apps.delete
  • Destroy a volumefly_io_machines.volumes.delete
  • Release an app's IP addressfly_io_machines.ip_assignments.delete

  • Delete a cluster userfly_io_machines.postgres.users.delete
  • Delete a database from a clusterfly_io_machines.postgres.databases.delete

  • Restart a machinefly_io_machines.machines.restart
  • Delete an app secret keyfly_io_machines.secret_keys.delete
  • Remove a hostname and all its certificatesfly_io_machines.certificates.delete
  • Release a machine leasefly_io_machines.machines.lease.delete
  • Remove a hostname's ACME certificatesfly_io_machines.certificates.acme.delete
  • Remove a hostname's custom certificatefly_io_machines.certificates.custom.delete
  • Detach a Managed Postgres cluster from an appfly_io_machines.postgres.attachments.delete

  • Rotate a cluster user's passwordfly_io_machines.postgres.users.rotate_password
  • Delete one machine metadata valuefly_io_machines.machines.metadata.key.delete

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Cost

What Fly.io Machines costs on actionlake.

Every Fly.io Machines action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Fly.io Machines refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions

The Fly.io Machines MCP server, answered.

Is there a Fly.io Machines MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 99 Fly.io Machines actions across machines, postgres, secret keys and certificates, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Fly.io Machines.

What do I need to connect Fly.io Machines?

Fly.io API token (from `fly tokens create org` or `fly tokens deploy`; paste the whole value, including any `FlyV1 `…. The free call account { op: "connections.requirements", service: "fly_io_machines" } lists exactly what to paste.

Can an AI agent delete or change things in Fly.io Machines?

Only if its key allows it, and only with an explicit confirmation. 18 Fly.io Machines actions are destructive, including destroy a machine, delete an app and destroy a volume. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Fly.io Machines API limit?

actionlake paces every call to the limits in the Fly.io Machines service file: 3 calls a second per connection. Repeated reads are answered from cache (25 Fly.io Machines actions can be), which never reaches Fly.io Machines.

What does a Fly.io Machines action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (99 Fly.io Machines actions page). Cache hits, searches, dry runs and calls Fly.io Machines refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Fly.io Machines API does it cover?

The Machines API 1.0 (OpenAPI 3.1.0) at api.machines.dev. It is built from Fly.io Machines's documentation as read on 23 October 2026. 99 actions in 12 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Fly.io Machines data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Fly.io Machines credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
