## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__sms-verify__post_estimate_cost` `mcp__sms-verify__post_send_numeric_verify` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `post_send_numeric_verify`

- The name "post_send_numeric_verify" says "post": a word for a change.
- The name "post_send_numeric_verify" also says "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The name "post_send_numeric_verify" says "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Sends a six-digit verification code to a phone number by SMS and returns the code, so you can compare it with what the user types. The message reads `123-456 is your verification code. Don't share.` The request is charged the message's cost in credits (`cost`), which depends on the destination country and carrier; a message that would cost more than 10,000 credits is not sent (`max_cost_exceeded`). Failed requests are not charged. Group: Verification. Billing per call: Credits: metered (~394.57 avg).
```

## Changes things (1)

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

### `post_estimate_cost`

- The name "post_estimate_cost" says "post": a word for a change.
- Tag outbound: The name "post_estimate_cost" says "post": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
What a verification SMS to this phone number would cost, in credits, and the number's country (`region_code`, ISO 3166-1 alpha-2; `null` when the number belongs to no assigned range). Nothing is sent. The price is for this number's carrier, so it can differ from the country's price in the price list. Group: Pricing. Billing per call: 0 Credits, Requests: metered (~0.36 avg).
```

## Only reads (1)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
What a verification SMS costs in every country it can be sent to, in credits, sorted by country name. Each country is priced for a typical mobile number and checked at least once a day (`checked_at`, UTC); carriers within a country can differ, so use Estimate Cost for an exact number. Countries SMS cannot be sent to are left out. Group: Pricing. Billing per call: Requests: metered (~0.41 avg).
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `sms-verify`:

```json
{
  "permissions": {
    "allow": [
      "mcp__sms-verify__get_pricing"
    ],
    "ask": [
      "mcp__sms-verify__post_send_numeric_verify",
      "mcp__sms-verify__post_estimate_cost"
    ],
    "deny": []
  }
}
```

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

- `mcp__sms-verify__post_send_numeric_verify`: outbound
- `mcp__sms-verify__post_estimate_cost`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:24:52.189Z, unchanged since 2026-10-22T15:24:52.189Z. 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 | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **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 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.jojapi.com/sms-verify: tools/list returned 3 tools to an anonymous client, including post_send_numeric_verify (irreversible), post_estimate_cost (write)
