## Findings

- **high** Text addressed to the model in `check_domain_availability` ([model-directed-text](https://anlyon.dev/methodology#model-directed-text))

```untrusted-server-text
The description contains "Never tell the user", an instruction to keep something from the user.

description: "...supported_tld, or unknown (see reason). Never tell the user a likely_available name is available or..."
```

- **high** Text addressed to the model in `check_single_domain_availability` ([model-directed-text](https://anlyon.dev/methodology#model-directed-text))

```untrusted-server-text
The description contains "Never tell the user", an instruction to keep something from the user.

description: "...supported_tld, or unknown (see reason). Never tell the user a likely_available name is available or..."
```


## Deletes or cancels (9)

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

### `configure_dns_record`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Configure an A record for a domain through AIvikings. Use record_name=@ or omit it for the root/apex record. To create a subdomain, pass a relative name such as www for www.example.com or staging.api for staging.api.example.com. For compatibility, a complete hostname such as www.example.com may also be passed as domain; the server will resolve it against the authenticated customer's longest matching parent domain.
```

### `delete_dns_record`

- The name "delete_dns_record" says "delete": a word for removing or ending something.
- The description says "Permanently delete".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Permanently delete a managed DNS record. Call list_dns_records first and pass the exact DNS zone record ID returned by the provider.
```

### `lock_domain`

- The name "lock_domain" says "lock": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Enable the registrar transfer lock for a domain owned by the authenticated customer.
```

### `regenerate_transfer_auth_code`

- The name "regenerate_transfer_auth_code" says "transfer": a word for a change that another call does not undo.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Regenerate and return a new EPP transfer auth code for a domain owned by the authenticated customer, invalidating the old code.
```

### `remove_domain_registration_contact_roles`

- The name "remove_domain_registration_contact_roles" says "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Remove selected default domain-registration roles from one existing contact handle. Set remove_registrant, remove_admin, remove_technical, and/or remove_billing to true; false leaves that role unchanged. This does not delete the contact. Removing a role without assigning it to another contact can make registration validation fail unless register_domain is called with an explicit registration-ready contact_handle.
```

### `unlock_domain`

- The name "unlock_domain" says "unlock": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Disable the registrar transfer lock for a domain owned by the authenticated customer before a transfer-out.
```

### `update_dns_record`

- The name "update_dns_record" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replace an existing managed DNS record. Call list_dns_records first and pass its DNS zone record ID. All record fields must describe the desired replacement.
```

### `update_nameservers`

- The name "update_nameservers" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Replace a domain's nameservers through AIvikings.
```

### `update_registrant_contact`

- The name "update_registrant_contact" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Update the registrant contact for a domain owned by the authenticated customer. Pass contact_handle by itself to apply an existing reusable contact without copying its fields into a new contact record. Name, organization, or email changes require acknowledge_transfer_lock=true because they initiate registrant verification and can impose a 60-day inter-registrar transfer lock. A provider-accepted change is reported as verification pending until the registrant completes that step.
```

## Can't be undone (1)

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

### `domain_transfer`

- The name "domain_transfer" says "transfer": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Transfer a domain in through AIvikings.
```

## Changes things (9)

```untrusted-server-text
Add a managed DNS record to a domain owned by the authenticated customer. Supported types are A, AAAA, CNAME, MX, TXT, NS, and SRV. Relative names are expanded below the domain, including nested names such as staging.api; use @ for the zone apex. SRV records require port and weight.
```

### `assign_domain_registration_contact_roles`

- The name "assign_domain_registration_contact_roles" says "assign": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Assign one existing contact handle as the default for selected domain-registration roles. Set assign_registrant, assign_admin, assign_technical, and/or assign_billing to true; false leaves that role unchanged. Assigning a role replaces any previous default for that role. Use this when registration validation reports a missing registrant, admin, technical, or billing contact.
```

### `check_domain_availability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: high model-directed-text

Description, as the server wrote it:

```untrusted-server-text
Check availability for up to 200 domain names through AIvikings. depth="fast" answers in about a second without contacting the registry, for brainstorming many names; depth="confirm" (default) asks the registry about every name that might be free and returns prices. A good flow: check many names with depth="fast", then confirm the shortlist with depth="confirm". Each result has a status: available (confirmed by the registry, with price and is_premium), likely_available (no registration found by fast checks, NOT confirmed and has no price), taken, reserved, pending_delete, invalid, unsupported_tld, or unknown (see reason). Never tell the user a likely_available name is available or quote a price for it: confirm it first with depth="confirm". domain_type only classifies name length. Use get_domain_pricing for full price schedules.
```

### `check_single_domain_availability`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: high model-directed-text

Description, as the server wrote it:

```untrusted-server-text
Check availability for one domain through AIvikings. depth="confirm" (default) asks the registry and returns the price; depth="fast" answers quickly without a price. Each result has a status: available (confirmed by the registry, with price and is_premium), likely_available (no registration found by fast checks, NOT confirmed and has no price), taken, reserved, pending_delete, invalid, unsupported_tld, or unknown (see reason). Never tell the user a likely_available name is available or quote a price for it: confirm it first with depth="confirm". domain_type only classifies name length. Use get_domain_pricing for the full price schedule.
```

### `create_contact`

- The name "create_contact" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a reusable contact for domain registration. Use list_contact_countries and list_contact_states to choose valid country and state names. The returned handle can be passed to register_domain and reused for multiple domains. When handle is omitted, it is generated from the company initials (or contact-name initials), four digits, and the country code.
```

### `create_customer`

- The name "create_customer" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create a new customer without generating or returning an API key.
```

### `reconcile_provider_client`

- The description's first verb is "link": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Link or create the authenticated customer's registrar client account, preventing duplicate creation.
```

### `register_domain`

- 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
Register a domain through AIvikings using the authenticated account's configurable default nameservers when nameservers are omitted. Call list_domain_registration_contacts first and pass contact_handle to use one complete reusable contact for registrant, admin, technical, and billing roles. If there is no registration-ready contact, call create_contact before registration. Set currency to the same USD or EUR currency used for the price quote; otherwise the customer's preferred currency is used. If that wallet is short and automatic conversion is enabled, only the missing amount is converted from the other supported wallet. For a premium domain, first show the current get_domain_pricing quote to the user and set allow_premium=true only after the user explicitly accepts that price.
```

### `renew_domain`

- 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
Renew a domain through AIvikings.
```

## Only reads (15)

- The name "get_domain_audit_log" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read append-only domain change history for the authenticated customer. Omit domain for portfolio history. Requires audit:read. Results are newest recorded first; pass next_cursor with the same filters for another page. Times must include a timezone. Requested, state_changed, and outcome events share an operation_id. Accepted is not proof of provider completion. History starts when domain auditing was enabled; agent labels are self-reported.
```

### `get_domain_pricing`

- The name "get_domain_pricing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a fresh price quote for one domain. Returns customer-facing registration, renewal, and transfer prices, plus is_premium so the user can be told when premium pricing applies. Omit currency to use the returned currency; USD and EUR can be requested explicitly. Prices are not converted: if the requested currency is unavailable, price fields are null with a price_unavailable_reason. Never exposes upstream cost prices.
```

### `get_domain_status`
