## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__sanctions-screener__list_status` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__sanctions-screener__list_status` |
| 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.

### `audit_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
Screens 1–50 subjects and returns a self-contained HTML report (result.html): timestamp, each list with its version / fetched-at / SHA-256, the inputs, every hit with its explanation, and an explicit no-match statement for clear subjects — suitable for the client's AML file (open in a browser, print to PDF). One charge per report. Example: subjects [{name:'Qusay Saddam Hussein', dob:'1966'}], case_reference 'KYC-2026-0412', prepared_by 'MLRO'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.
```

### `screen_batch`

- 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
Each subject may carry dob, nationality, entity_type, id_number and your reference. Identical rows are screened once (charged once). Returns per-subject decision_hint, hit_count, top_score and the top 5 hits, plus summary counts (clear / review / likely_match). Charged per unique name. Example: subjects [{name:'Ali Kony', reference:'C-17'}, {name:'شركة الأمل للتجارة', entity_type:'entity'}], default_nationality 'AE'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.
```

### `screen_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 person, company, vessel or aircraft name against OFAC SDN + Consolidated, UN, EU, UK and the UAE Local Terrorist List. Returns up to 20 hits sorted by score with list, listed_name, aliases_matched, score, match_strength (exact / strong / possible / weak), matched_on (which alias, which normalisation, DOB / nationality / type agreement), programs, listed_on, DOBs, nationalities, id_numbers, reference and source_url, plus decision_hint. Example: name 'Mohamed Hussein Al-Tikriti', dob '1966', nationality 'IQ', entity_type 'individual'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.
```

## Only reads (2)

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

### `explain_match`

- The name "explain_match" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Normalises both names step by step (Unicode, Arabic letter folding, honorifics/particles dropped, merged 'Abdul…' forms split, romanisation variants folded) and returns every score component (token_sort, token_set, Jaro-Winkler, subset, or the cross-script skeleton) and the resulting score / strength. Free. Example: name_a 'Abd al-Rahman Al Shaikh', name_b 'عبدالرحمن الشيخ'. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.
```

### `list_status`

- The name "list_status" says "list": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.
- 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
Per list: entries (individuals / entities / vessels / aircraft), aliases, fetched_at, days_since_fetch (stale flag when older than 7 days), official source URL and page, SHA-256 of the downloaded file, licence/terms, and any failures of the last refresh. Free. Call it before relying on a 'clear' result in a regulated process. Response: result plus data_confidence, estimated_items[], sources[] (official list pages), data_version (snapshot id), warnings[] (e.g. a list snapshot older than 7 days) and a disclaimer. Lists: ofac_sdn, ofac_cons, un, eu, uk, uae. Names are never logged; matching is deterministic (no AI) and runs offline against the bundled snapshot.
```

## Claude Code permissions

      "mcp__sanctions-screener__audit_report"
    ],
    "deny": []
  }
