**8 tools: 1 can delete or cancel things, 4 change things and 3 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 4 | ask |
| Only reads | read | 3 | allow |

## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__dnsmint__list_hostnames` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__dnsmint__start_checkout` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **info** The word "credentials" in `list_hostnames` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "Every hostname this credential can see, with how many are active and t..."
```


## Deletes or cancels (1)

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

### `release_hostname`

- 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
PERMANENTLY give up a hostname. Read this before calling it.

A released hostname is tombstoned and is never issued again, to anyone, including this account. There is no undo and it cannot be re-minted. This is not like deleting a DNS record.

Only call this when the name is genuinely finished with and a human has asked for it. If the goal is to stop serving, repoint it or stop the machine instead.

Pass the hostname in `confirm` exactly as it appears, so a name cannot be released by guessing an id.
```

## Changes things (4)

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

### `diagnose_hostname`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Why a hostname is or is not working: what the nameservers answer, what public resolvers see, and whether a certificate has been issued. Use this before assuming something is broken; a name minted moments ago may simply not have propagated.
```

### `mint_hostname`

- 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 an address and get back a stable hostname that survives the address changing. This is the tool to use when a machine or agent needs a name.

The address class is fixed for the life of the name: mint with a public address and it stays public, mint with a private one and it stays private. Crossing later is refused, so pass the address the machine will actually serve on. A target fixes the class the same way, from whatever it resolves to.

A hostname is one label above a domain. Names below a hostname are not hostnames and cannot be minted.

Newly minted names report status 'pending' and go 'live' within about a minute.
```

### `repoint_hostname`

- 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
Point an existing hostname at a new address. This is what makes the name worth having: the machine moves, the name does not, and everything holding the URL keeps working.

Repointing within an address class is free, including between IPv4 and IPv6. Crossing between public and private is refused, because one name resolving public then private is how DNS rebinding works.
```

### `start_checkout`

- The name "start_checkout" says "start": 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
Get a payment link the account owner opens to raise this account's limits. Call this when minting fails because the account is at its hostname cap or has no plan.

This charges nothing and buys nothing. It returns a URL, and the purchase only happens if a person opens it and enters card details. Give the URL to the human you are working with and say what it costs; do not try to complete it yourself, and do not call this repeatedly hoping the limit lifts. Nothing changes until somebody pays.

Only for an account with no plan yet. If one already exists you get the billing page back instead, because changing a running plan charges a card on file and is a person's decision.

Both numbers default to what the account already holds, so asking for hostnames alone keeps the domains. A plan smaller than what is in use is refused.
```

## Only reads (3)

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

### `get_hostname`

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

Description, as the server wrote it:

```untrusted-server-text
One hostname's status and certificate mode. Does not say where it points: DNS is the authoritative answer for that, so use diagnose_hostname or resolve the name.
```

### `get_plan`

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

Description, as the server wrote it:

```untrusted-server-text
What this account's plan allows and how much of it is used: hostnames, dedicated domains, and whether a plan is active at all. Also says whether a checkout is outstanding, which is how you find out a payment link you were given has not been completed yet.

Call this after handing someone a checkout URL, instead of retrying a mint to see if it worked. It costs nothing and changes nothing.
```

### `list_hostnames`

- The name "list_hostnames" says "list": a word for reading.
- Tag private-data: The description's first sentence says "credential": it reads secrets.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Every hostname this credential can see, with how many are active and the plan's cap. Check the cap before minting: a hostname is the unit the plan counts.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `dnsmint`:

```json
{
  "permissions": {
    "allow": [
      "mcp__dnsmint__list_hostnames",
      "mcp__dnsmint__get_plan",
      "mcp__dnsmint__get_hostname"
    ],
    "ask": [
      "mcp__dnsmint__diagnose_hostname",
      "mcp__dnsmint__mint_hostname",
      "mcp__dnsmint__repoint_hostname",
      "mcp__dnsmint__start_checkout"
    ],
    "deny": [
      "mcp__dnsmint__release_hostname"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__dnsmint__list_hostnames`: private-data
- `mcp__dnsmint__start_checkout`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:30:49.881Z, unchanged since 2026-10-22T14:30:49.881Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `5` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `https://dnsmint.com/.well-known/oauth-protected-resource/mcp` |
| Authorization servers | `https://dnsmint.com` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `yes` |
| Client ID metadata documents | `no` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 5 tools that change things (1 destructive, 4 write). Whether a call also works without credentials was not tested: tools are never called.

https://dnsmint.com/mcp: tools/list returned 8 tools to an anonymous client, including release_hostname (destructive), diagnose_hostname (write), mint_hostname (write), repoint_hostname (write), start_checkout (write)
```
