**11 tools: 1 can delete or cancel things, 1 do something that can't be undone, 7 change things and 2 only read.**

## 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__deposits__license_status` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

```untrusted-server-text
The server marks "deposit_statement_pdf" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "call": a word for a change.
```


## Deletes or cancels (1)

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

### `deposit_delete`

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

Description, as the server wrote it:

```untrusted-server-text
Delete a deposit that never moved money, freeing that month's free-tier slot. One with anything applied or refunded is refused, naming it, since a payment or refund would be left with nothing behind it.
```

## Can't be undone (1)

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

### `deposit_refund`

- The name "deposit_refund" says "refund": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Give part or all of a held deposit back to the client, with the date and how it was sent. Refuses more than is still held. The invoice server is not touched: a refund is not a payment.
```

## Changes things (7)

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

### `deposit_apply`

- The name "deposit_apply" says "apply": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Apply part of a held deposit to one invoice: it records that amount as a PAYMENT through the invoice server. amount_minor defaults to the lesser of held and owed. More than either, or a pre-arrival date, is refused.
```

### `deposit_balance`

- 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
Answer "how much of theirs am I holding?" for one client or everyone: received, applied to invoices, refunded and still held, one row per currency, never added across them. Reads only; deposit_list shows each deposit.
```

### `deposit_record`

- 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
Record a security or retainer deposit received from a client, in minor units, with its currency, the date it arrived and the bank reference. Returns the DEP-YYYY-NNNN id.
```

### `deposit_statement_pdf`

- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Call this tool to render one client's A4 deposit statement and return a download link valid for one hour. Titled DEPOSIT STATEMENT, every movement in date order, closing with what is still held. Pro.
```

### `deposit_statement_text`

- 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
Turn one client's deposits into a plain-text statement to paste into an email: every movement in date order and the closing balance held. Pass currency when they have more than one. Also a .txt download link valid one hour. Free on every tier.
```

### `deposits_report`

- 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
The deposit book at a date: held per currency, received, applied and refunded, the oldest holdings with days held, and every deposit older than N days with nothing applied. Pro; deposit_balance is free.
```

### `license_activate`

- 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
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
```

## Only reads (2)

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

### `deposit_list`

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

Description, as the server wrote it:

```untrusted-server-text
List deposits newest first: DEP number, client, kind, date, reference and what was received, applied, refunded and still held, with the same four totalled per currency. Filter by client, status, kind, date.
```

### `license_status`

- The name "license_status" says "status": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__deposits__deposit_list",
      "mcp__deposits__license_status"
    ],
    "ask": [
      "mcp__deposits__deposit_record",
      "mcp__deposits__deposit_apply",
      "mcp__deposits__deposit_refund",
      "mcp__deposits__deposit_balance",
      "mcp__deposits__deposit_statement_text",
      "mcp__deposits__deposit_statement_pdf",
      "mcp__deposits__deposits_report",
      "mcp__deposits__license_activate"
    ],
    "deny": [
      "mcp__deposits__deposit_delete"
    ]
  }
}
```

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

- `mcp__deposits__license_status`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:25:41.650Z, unchanged since 2026-10-22T15:25:41.650Z. 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 | `9` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |

| Authorization servers | `https://mcp.zovo.one` |

| 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 9 tools that change things (1 destructive, 1 irreversible, 7 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.zovo.one/mcp/deposits: tools/list returned 11 tools to an anonymous client, including deposit_delete (destructive), deposit_refund (irreversible), deposit_record (write), deposit_apply (write), deposit_balance (write) and 4 more
