## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `prepare_screening_receipt`

- 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
Bundle the screening checks into one idempotent Ed25519-signed receipt committing to the HASHED inputs, sources, snapshot checksum, retrieval times and decision states — provable evidence of WHAT was screened and WHEN. Attests the checks, not a clearance or a 'not sanctioned' claim. Screening evidence only; not a legal/compliance determination, not a clearance.
```

### `screen_sanctioned_identifier`

- 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
Deterministic EXACT match of an identifier (passport / national id / registration / other) against listed designations' identifiers — no fuzzy matching. 'match' / 'clear' / 'unavailable'. Screening evidence only; not a legal/compliance determination, not a clearance. A 'clear' is not a guarantee of non-designation — snapshot-scoped.
```

### `screen_sanctioned_name`

- 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
Screen a counterparty name against a dated snapshot of the official EU Consolidated Financial Sanctions List. Returns ranked CANDIDATE designations with deterministic match scores, or 'clear'/'needs_review'/'possible_match'/'match'; no snapshot → 'unavailable'. Never a false clear on outage or fuzzy input. Screening evidence only; not a legal/compliance determination, not a clearance. A 'clear' is not a guarantee of non-designation — snapshot-scoped. Every result carries source, publication date, checksum and retrieval time.
```

## Only reads (2)

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

### `get_sanctions_listing`

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

Description, as the server wrote it:

```untrusted-server-text
Return the full official listing detail (names, programme, legal basis, listing date, identifier types, countries) for a candidate logicalId surfaced by a prior screen, with provenance. 'found' / 'not_found' / 'unavailable'. Screening evidence only; not a legal/compliance determination, not a clearance. Every result carries source, publication date, checksum and retrieval time.
```

### `list_sanctions_regimes`

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

Description, as the server wrote it:

```untrusted-server-text
Enumerate the EU sanctions programmes/regimes present in the snapshot (regulation/legal basis, since date, subject count) — the policy-layer read. 'found' / 'unavailable'. Reference only, not legal advice. Every result carries source, publication date, checksum and retrieval time.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `eu-sanctions-preflight`:

```json
{
  "permissions": {
    "allow": [
      "mcp__eu-sanctions-preflight__get_sanctions_listing",
      "mcp__eu-sanctions-preflight__list_sanctions_regimes"
    ],
    "ask": [
      "mcp__eu-sanctions-preflight__screen_sanctioned_name",
      "mcp__eu-sanctions-preflight__screen_sanctioned_identifier",
      "mcp__eu-sanctions-preflight__prepare_screening_receipt"
    ],
    "deny": []
  }
}
```

- **warn** 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://sanctions.mcp.jithox.com/mcp: tools/list returned 5 tools to an anonymous client, including screen_sanctioned_name (write), screen_sanctioned_identifier (write), prepare_screening_receipt (write)
