Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 73, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (5)

### `screen_name` (~227 tokens)

Screen a name against the OFAC SDN list

Screens one person, company, vessel or aircraft name against the U.S. Treasury OFAC SDN sanctions list and returns potential matches with scores (0-100, 100 = identical) and an explanation of each. Give year of birth and country when known so conflicts can be flagged.

Input parameters:

- `country` (string|null): The party's country, if known. Matches whose listed addresses are all in other countries are flagged.
- `maxResults` (integer): Maximum number of matches to return, 1-50. Default 10.
- `minScore` (number): Lowest score to return, 0-100. Default 85.
- `name` (string, required): The name to screen, in any order, e.g. "John Doe" or "DOE, John".
- `type` (string|null): Only screen this kind of entry: individual, entity, vessel or aircraft. Omit to screen all.
- `yearOfBirth` (integer|null): The party's year of birth, if known. Matches whose listed dates of birth differ by more than a year are flagged.

### `screen_names` (~91 tokens)

Screen several names

Screens up to 100 names against the OFAC SDN list and returns, for each, the number of potential matches and the best one. Use screen_name for full details on any name that has matches.

Input parameters:

- `minScore` (number): Lowest score to count as a potential match, 0-100. Default 85.
- `names` (array, required): The names to screen (at most 100).

### `get_sanctions_entry` (~73 tokens)

Look up an SDN entry

Returns the full published record of one OFAC SDN entry by its entry number: names, aliases, type, programs, dates of birth, addresses and remarks. Use it to review a potential match.

Input parameters:

- `entryId` (integer, required): The SDN entry number (ent_num) shown in screening results.

### `compare_names` (~102 tokens)

Explain how two names score

Scores two names against each other with the same method used for screening, and shows the whole-name score, the name-parts score and how each part paired. Useful to understand or explain a score.

Input parameters:

- `companies` (boolean): Treat the names as company names, ignoring legal forms such as LLC or LTD.
- `name` (string, required): The searched name.
- `otherName` (string, required): The name to compare with, e.g. a listed name or alias.

### `get_list_info` (~38 tokens)

SDN list status

Reports which copy of the OFAC SDN list the server is using: number of entries, where it came from and when it was downloaded.
