## Exfil surface

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

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

## Findings

No check matched anything in these tool definitions.


## Can't be undone (3)

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

### `issue_proforma`

- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Issue a proforma invoice for an UPCOMING balance top-up of the given USD amount (1–100000) and email it (default) to the invoice email, or to "to". Returns the number, due date and PDF link. Charges nothing — the proforma is paid by topping up at rixot.com/add-funds, after which the paid invoice appears automatically.
```

### `publish_basket`

- The name "publish_basket" says "publish": a word for a change that another call does not undo.
- Tag outbound: The name "publish_basket" says "publish": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Publish everything in your basket, paying from your account balance. If the balance is short it does nothing and reports how much more is needed. Topping up the balance is done in the dashboard only.
```

### `send_invoice`

- The name "send_invoice" says "send": a word for sending, and what is sent cannot be taken back.
- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The name "send_invoice" says "send": it sends or publishes something to other people. The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Email an existing invoice or proforma (exact number from list_invoices, e.g. RX-2026-000123 or PF-2026-000007) with its PDF link — to the invoice email, or to "to".
```

## Changes things (1)

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

### `order_backlink`

- The description's first verb is "add": a word for a change.
- Tag outbound: The input takes a URL (input.target_url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Add backlink order(s) to your basket (no charge yet). Pick ONE content mode: (auto) send donor_ids + target_url + keyword and we write the article; (prompt) also send "recommendations" to steer the AI writer — fetch the editable base prompt with get_article_prompt first; (own) send target_url + "content" (+ optional "title","article_url") to publish your own ready HTML (requires own-content enabled). Then call publish_basket to pay from balance.
```

## Only reads (6)

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

### `check_balance`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the Rixot account balance (USD).
```

### `get_article_prompt`

- The name "get_article_prompt" says "get": a word for reading.
- Tag untrusted-input: The input takes a URL (input.target_url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.target_url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Return our default article-generation prompt so you can see exactly how the article is written and, optionally, edit it. Pass the edited guidance back as "recommendations" in order_backlink. The output contract (JSON title/html/url, one dofollow link, no images) is fixed so the article can be published.
```

### `get_basket`

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

Description, as the server wrote it:

```untrusted-server-text
List what is currently in your basket (inspect the drafted articles/placements before publishing).
```

### `list_donors`

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

Description, as the server wrote it:

```untrusted-server-text
Find marketplace donor sites for a niche/budget. Filters: domain_filter (substring), dr_min (Domain Rating >=), price_max / price_min (USD per link), page (20 per page).
```

### `list_invoices`

- The name "list_invoices" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
List the account's billing documents: paid invoices (one per completed balance top-up, numbers RX-…) and proforma invoices for upcoming top-ups (PF-…), each with amount, status and a PDF link. Company name, address, VAT and the invoice email are edited at rixot.com/billing.
```

### `list_links`

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

Description, as the server wrote it:

```untrusted-server-text
List your ordered backlinks with status and published URL.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rixot__check_balance",
      "mcp__rixot__list_donors",
      "mcp__rixot__list_links",
      "mcp__rixot__get_basket",
      "mcp__rixot__list_invoices"
    ],
    "ask": [
      "mcp__rixot__get_article_prompt",
      "mcp__rixot__order_backlink",
      "mcp__rixot__publish_basket",
      "mcp__rixot__issue_proforma",
      "mcp__rixot__send_invoice"
    ],
    "deny": []
  }
}
```

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

- `mcp__rixot__list_links`: untrusted-input
- `mcp__rixot__get_article_prompt`: untrusted-input, outbound
- `mcp__rixot__order_backlink`: outbound
- `mcp__rixot__publish_basket`: outbound
- `mcp__rixot__list_invoices`: private-data
- `mcp__rixot__issue_proforma`: outbound

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (3 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://ai.rixot.com/mcp: tools/list returned 10 tools to an anonymous client, including publish_basket (irreversible), issue_proforma (irreversible), send_invoice (irreversible), order_backlink (write)
