## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__smartaccounts__smartaccounts_get_client_balance` `mcp__smartaccounts__smartaccounts_get_vendor_balance` |
| 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. | none |

## Findings

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

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

annotations: {"readOnlyHint":true}; The name "smartaccounts_list_articles" says "list": a word for reading.
```

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

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

## Deletes or cancels (4)

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

### `smartaccounts_create_client`

- The name "smartaccounts_create_client" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Add a new client (purchasesales/clients:add). Search first with smartaccounts_list_clients so a client is not created twice. Returns clientId and the generated referenceNumber. This creates a real accounting record in the company's books. This server cannot edit or delete it; correct it in SmartAccounts. It never retries: if a reply is unclear, look in SmartAccounts before calling again. The vendor limit is 60 requests per minute and 1000 per 24 hours; every call here is one request.
```

### `smartaccounts_create_ledger_entry`

- The name "smartaccounts_create_ledger_entry" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Post a manual general ledger entry (journal entry, general/entries:add) in EUR. Debits must equal credits. Account codes come from smartaccounts_list_accounts. Fails if the period is locked. Returns id, number and amount. This creates a real accounting record in the company's books. This server cannot edit or delete it; correct it in SmartAccounts. It never retries: if a reply is unclear, look in SmartAccounts before calling again. The vendor limit is 60 requests per minute and 1000 per 24 hours; every call here is one request.
```

### `smartaccounts_create_payment`

```untrusted-server-text
Record a bank or cash payment against one or more invoices (purchasesales/payments:add): a client paying a sales invoice, or a payment to a vendor for a purchase invoice. Use smartaccounts_list_bank_accounts or _list_cash_accounts for account_name, and the invoice ids from the invoice lists. The currency must match the account's currency. Returns paymentId, number and amount. This creates a real accounting record in the company's books. This server cannot edit or delete it; correct it in SmartAccounts. It never retries: if a reply is unclear, look in SmartAccounts before calling again. The vendor limit is 60 requests per minute and 1000 per 24 hours; every call here is one request.

The client must exist (smartaccounts_list_clients); each row's code must be an article code (smartaccounts_list_articles) and vat_pc a VAT code (smartaccounts_list_vat_rates). Fails if the period is locked. Returns invoiceId, number and the totals. This creates a real accounting record in the company's books. This server cannot edit or delete it; correct it in SmartAccounts. It never retries: if a reply is unclear, look in SmartAccounts before calling again.
