## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__satsdns__account_objects` `mcp__satsdns__account_order` `mcp__satsdns__check` `mcp__satsdns__claim` `mcp__satsdns__dnssec_info` `mcp__satsdns__domain_check` `mcp__satsdns__hostname_create` `mcp__satsdns__hostname_status` `mcp__satsdns__hostname_update` `mcp__satsdns__info` `mcp__satsdns__order_status` `mcp__satsdns__records_change` `mcp__satsdns__records_list` `mcp__satsdns__renew` `mcp__satsdns__renewal_address` `mcp__satsdns__secondary_create` `mcp__satsdns__token_rotate` `mcp__satsdns__zone_add_queries` `mcp__satsdns__zone_create` `mcp__satsdns__zone_status` |

## Findings

- **warn** Annotations that disagree with the tool in `order_status` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "order_status" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The name "order_status" says "status": a word for reading.
```


## Deletes or cancels (3)

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

### `hostname_update`

- The name "hostname_update" says "update": a word for a change.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: sets the hostname's A, AAAA, TXT, ACME TXT or HTTPS records; fields left out stay as they are, [] deletes. Give explicit public addresses: the caller's own address ('auto') is not available here, because through MCP it would be your client's server, not your machine (routers use /nic/update). Pass the hostname token (jdh_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and transcript: treat it like a password.
```

### `records_change`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: applies up to 100 rrset changes at once, all or none. Each item REPLACEs one rrset (name and type) with the given records, or DELETEs it. Deleting records can take a site or mail offline: change only what your user asked for. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and transcript: treat it like a password.
```

### `token_rotate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: makes a new token for a zone or hostname; the old one stops working at once. Use it when a token may have leaked (tokens pass through model context). Authorize with the current token or, for an object in your account, with nip98. The new token is shown once. Called without nip98 it returns signature_required: the exact URL, method and body to sign, the body's sha256 and an unsigned kind 27235 event template (with proof of work for accounts without a paid order). Sign that, then call again with the same arguments plus nip98. Each signed event works once, within 60 s. Secrets that are ours to receive: object tokens, account API keys (jdk_), signed NIP-98 events; never a private key (nsec or 64 hex characters), wallet connection string or seed words. A raw hex key or seed words inside a sentence cannot be caught here.
```

## Changes things (14)

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

### `account_objects`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free, read-only: the account's state and limits, or the zones, hostnames or invoices it owns. With api_key, only the objects the key's scope covers and only their invoices (the account view of limits and counts is the same for every key). Called without nip98 it returns signature_required: the exact URL, method and body to sign, the body's sha256 and an unsigned kind 27235 event template (with proof of work for accounts without a paid order). Sign that, then call again with the same arguments plus nip98. Each signed event works once, within 60 s. Secrets that are ours to receive: object tokens, account API keys (jdk_), signed NIP-98 events; never a private key (nsec or 64 hex characters), wallet connection string or seed words. A raw hex key or seed words inside a sentence cannot be caught here.
```

### `account_order`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Orders a product into your account, paid by its own invoice: Lightning (15 min) or a new on-chain address (orders of 5,000 sats and up). Prices as in info. pay=check runs the free checks only and makes no invoice: use it first. Refused orders make no invoice. New objects need nip98; renewals and extra queries also work with an api_key whose scope covers the object. Pay only within what your user allowed, then poll order_status with the invoice id. Accounts without a paid order are limited (see info, accounts.npub_limits). Called without nip98 it returns signature_required: the exact URL, method and body to sign, the body's sha256 and an unsigned kind 27235 event template (with proof of work for accounts without a paid order). Sign that, then call again with the same arguments plus nip98. Each signed event works once, within 60 s. Secrets that are ours to receive: object tokens, account API keys (jdk_), signed NIP-98 events; never a private key (nsec or 64 hex characters), wallet connection string or seed words. A raw hex key or seed words inside a sentence cannot be caught here.
```

### `check`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: runs the checks a paid call runs before payment (name rules, availability, delegation, limits) without creating an invoice, and returns the price. For zone_create and secondary_create of a new zone it answers delegation_missing with the zone's own nameserver pair (expected_ns) and an ns_ticket: set exactly those NS records at the domain's registrar, wait until the registry publishes them, then call again with ns_ticket. This opens a nameserver offer (limited per caller), so it is not read-only.
```

### `claim`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: puts a zone or hostname bought with a token into your Nostr account, so you get expiry reminders by DM and can manage it with API keys. If another account owns it, a 72-hour recovery starts instead and that owner is told. Called without nip98 it returns signature_required: the exact URL, method and body to sign, the body's sha256 and an unsigned kind 27235 event template (with proof of work for accounts without a paid order). Sign that, then call again with the same arguments plus nip98. Each signed event works once, within 60 s. Secrets that are ours to receive: object tokens, account API keys (jdk_), signed NIP-98 events; never a private key (nsec or 64 hex characters), wallet connection string or seed words. A raw hex key or seed words inside a sentence cannot be caught here. The signature_required answer shows the body with the token masked; its sha256 covers the real token.
```

### `dnssec_info`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: the DS record(s) to enter at the registrar, and what the parent zone publishes now. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and transcript: treat it like a password.
```

### `domain_check`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: whether a .com, .net or .org name is available and its price in sats. Tightly rate-limited. Registration itself is not offered through this server.
```

### `hostname_create`

- The name "hostname_create" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Creates a dynamic hostname such as myhome.dynkite.com. The answer gives the hostname token once (keep it: hostname_update and routers use it). Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then call again with the same arguments plus l402='<macaroon>:<preimage>', or call with cashu='<token>'. Every request is checked for free before an invoice is made; use check first.
```

### `info`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: prices in sats per product and period, nameservers, limits, record types, accepted Cashu mints, how paying works, and the steps to host a zone.
```

### `order_status`

- The name "order_status" says "status": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Free: the invoice's state (paid, fulfilled, expired, ...) and, after fulfilment, the result. A new object's token (and TSIG key) is shown once, only to a nip98 call, within 1 hour of fulfilment; an api_key sees the state only, and only of invoices for objects in its scope (invoice_not_found otherwise). Called without nip98 it returns signature_required: the exact URL, method and body to sign, the body's sha256 and an unsigned kind 27235 event template (with proof of work for accounts without a paid order). Sign that, then call again with the same arguments plus nip98. Each signed event works once, within 60 s. Secrets that are ours to receive: object tokens, account API keys (jdk_), signed NIP-98 events; never a private key (nsec or 64 hex characters), wallet connection string or seed words. A raw hex key or seed words inside a sentence cannot be caught here.
```

### `renew`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Extends a hosted zone, secondary zone or dynamic hostname by 30d or 1y from its current expiry. Needs no token: anyone may pay to extend any name. Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then call again with the same arguments plus l402='<macaroon>:<preimage>', or call with cashu='<token>'. Every request is checked for free before an invoice is made; use check first.
```

### `renewal_address`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Free: the Lightning address and LNURL that extend this zone or hostname pro rata when anyone pays it (no token needed to pay). Made once, then the same address is returned. Pass the zone token (jdz_...) from the create answer, or a scoped account API key (jdk_...) made in the dashboard. Either passes through your model context and transcript: treat it like a password.
```

### `secondary_create`

- The name "secondary_create" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
We serve your zone as secondaries, transferred from your primaries (public IPv4) with a TSIG key that the answer gives once. The same nameserver-pair step as zone_create applies (check first). Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then call again with the same arguments plus l402='<macaroon>:<preimage>', or call with cashu='<token>'. Every request is checked for free before an invoice is made; use check first.
```

### `zone_add_queries`

- The name "zone_add_queries" says "add": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Adds 1 million queries to a hosted zone's monthly allowance. Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then call again with the same arguments plus l402='<macaroon>:<preimage>', or call with cashu='<token>'. Every request is checked for free before an invoice is made; use check first.
```

### `zone_create`

- The name "zone_create" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Creates a hosted, DNSSEC-signed zone on our nameservers. First call check (tool zone_create): a new zone gets its own nameserver pair, which must be set at the registrar before the payment step; pass the ns_ticket from that answer. The answer gives the zone token once (keep it: it manages the zone), the nameservers and the DS record. Paid, no account. Without payment the call returns payment_required with the price, a Lightning invoice and a Cashu payment request; pay only within what your user allowed, then call again with the same arguments plus l402='<macaroon>:<preimage>', or call with cashu='<token>'. Every request is checked for free before an invoice is made; use check first.
```
