## Exfil surface

1 private-data -> untrusted-input -> outbound path in this server alone. Denying 1 outbound tool breaks every one: `mcp__pressmark__generate_document`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__pressmark__preview_document` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__pressmark__preview_document` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__pressmark__generate_document` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__pressmark__preview_document` | `mcp__pressmark__preview_document` | `mcp__pressmark__generate_document` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "generate_document" says "generate": a word for a change.
```

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

```untrusted-server-text
The server marks "convert_document" 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 name "convert_document" says "convert": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "record_payment" says "payment": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (2)

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

### `generate_document`

- The name "generate_document" says "generate": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.from.phone): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Generate a publication-ready vector PDF document (invoice, estimate, receipt, credit note, contract, NDA, purchase order, certificate, or real estate agreement) in under 25ms.
```

### `record_payment`

- The name "record_payment" says "payment": a word that usually means money moves, which cannot be taken back.
- 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
Record a full or partial payment against an invoice and instantly generate an official Receipt or updated partial-payment Invoice with remaining balance tracking.
```

## Changes things (2)

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

### `calculate_totals`

- 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
Calculate subtotal, tax amounts, discounts, grand total, and balance due for a document without full PDF synthesis.
```

### `convert_document`

- The name "convert_document" says "convert": 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
Convert an existing document (e.g. Estimate or Quote) to a Tax Invoice, Receipt, or Credit Note, preserving all line items, parties, and calculations.
```

## Only reads (2)

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
Get current subscription tiers, single-pass microtransactions, and checkout links.
```

### `preview_document`

- The name "preview_document" says "preview": a word for reading.
- Tag private-data: The name "preview_document" says "preview" and "document": it reads documents. The description's first sentence says "document": it reads documents.
- Tag untrusted-input: The description's first sentence says "uri": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Render a high-resolution 144-PPI PNG preview of the document as a Base64 Data URI for immediate visual inspection in chat.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pressmark__preview_document",
      "mcp__pressmark__get_pricing"
    ],
    "ask": [
      "mcp__pressmark__generate_document",
      "mcp__pressmark__calculate_totals",
      "mcp__pressmark__convert_document",
      "mcp__pressmark__record_payment"
    ],
    "deny": []
  }
}
```

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

- `mcp__pressmark__generate_document`: outbound
- `mcp__pressmark__preview_document`: private-data, untrusted-input
