## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `revoke_tunnel`

- The name "revoke_tunnel" says "revoke": a word for removing or ending something.
- The description says "cannot be undone".
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Retire a peer and hand its slot back to the plan's allowance. An agent that provisions a tunnel per short-lived worker and never revokes one exhausts the allowance and then cannot bring the next machine up. Revoking the peer that holds the public address stops inbound connections to it and cannot be undone by promoting another — only by bringing a new machine up.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `set_reverse_dns`

- The name "set_reverse_dns" says "set": a word for a change.
- The description's first verb is "publish": a word for a change that another call does not undo.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Publish a PTR record for an address on the lease. Live within a second; an empty hostname removes it.
```

## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_tunnel`

- The name "create_tunnel" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Provision a peer and return its WireGuard configuration. Three routing modes, and the right one depends on the machine.

source (the default) sends only traffic from the leased address through us and leaves the default route alone — but it is written with wg-quick PostUp rules that invoke `ip`, so it runs on Linux under wg-quick and nowhere else. On macOS it aborts and deletes the interface.

full works in every client but claims the default route, so it cannot run beside an always-on corporate VPN.

destinations routes only the addresses you name. It needs no PostUp and takes no default route, so it runs in any client on any platform, and it matches what is usually being bought — one partner seeing a fixed address. It survives beside a VPN that installs a default route, but not one that captures traffic below the routing table. It cannot receive inbound connections from anywhere but those destinations.
```

### `order_lease`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Place an order. The trial plan is free and activates immediately; paid plans return payment details and stay pending until settled. No account or card is needed to order. A second trial for the same billing email is refused — order a paid plan instead, which needs no approval.
```

### `renew_lease`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Raise an invoice for another term and keep the same addresses. This is how a trial becomes a paying customer: the address does not change, so whatever the customer's partner has already allowlisted goes on working. A trial cannot renew into itself, so name the plan to move to — called without one it returns the plans that can be moved to. Pressing it twice quotes the same reference rather than raising a second invoice.
```

### `set_autorenew`

- The name "set_autorenew" says "set": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Stop this lease charging the customer's card again, or start it again. Only a card subscription can be stopped — a bank transfer is a payment the customer sends us, so there is nothing of ours to cancel. Stopping is not a cancellation: the lease runs to the end of the period already paid for, and the same call turns it back on.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `lease_status`

- The name "lease_status" says "status": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Everything about one lease: whether it is active, which addresses it holds, its tunnels and when it renews.
```

### `list_plans`

- The name "list_plans" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The published catalogue with live prices and which payment methods each plan accepts. Prices are never hardcoded; read them here.
```
