## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 0/100
  - Malware scan not yet available for this package.

  - Actively maintained (last published 84 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1864 tokens (~155/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.

  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Changelog

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.

### 2026-08-03 (score 42, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-02 (score 41, +3)

- [functional improvement] Stability: unverified → 0.20

### 2026-08-01 (score 38, −6)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-27 (score 11)

First indexed and scored.

## MCP tools (12)

### `autocomplete` (~119 tokens)

Get entity name suggestions from a prefix (min 2 characters). USE WHEN: "suggest companies starting with X", "autocomplete company name", user is typing a name and needs quick suggestions. For full search results with pagination, use search_entity instead. Returns name suggestions with LEI and legal name for each match. FAILS WHEN: prefix is shorter than 2 characters. Falls back to fuzzy search automatically if the autocomplete endpoint is unavailable.

Input parameters:

- `limit` (integer): Max suggestions (default 10)
- `prefix` (string, required): Name prefix to complete

### `batch_lei_lookup` (~119 tokens)

Look up multiple LEI records in one request (max 100). USE WHEN: "look up these LEIs", "batch lookup", user provides 2+ LEI codes. Faster than calling lei_lookup repeatedly. FAILS WHEN: list is empty (provide at least one LEI), more than 100 LEIs (split into multiple calls), any individual LEI has invalid format (fix that specific LEI; the error message includes its position).

Input parameters:

- `leis` (string, required): Comma-separated LEI codes (max 100)

### `get_lei_issuer` (~115 tokens)

Get details about a specific LEI issuer (Local Operating Unit / LOU) by ID. USE WHEN: "details on this LOU", "issuer info". Returns issuer name, country, status, website, and count of sponsored LEIs. For all issuers worldwide, use list_lei_issuers. FAILS WHEN: issuer ID not found (use list_lei_issuers to get valid IDs).

Input parameters:

- `issuer_id` (string, required): LEI issuer ID (4-32 alphanumeric characters)

### `get_relationships` (~140 tokens)

Get corporate ownership and fund relationships for an entity.

USE WHEN: "who owns X?", "parent company", "subsidiaries", "fund manager"

Types: direct-parent, ultimate-parent, children, fund-manager, umbrella-fund, sub-funds. Returns relationship records with related entity LEI, legal name, relationship type, and status.

FAILS WHEN: LEI format invalid (must be 20 alphanumeric chars), no relationships of requested type exist (entity may have no parent; check get_reporting_exceptions for why ownership data is missing).

Input parameters:

- `lei` (string, required): LEI code
- `type` (string): Relationship type

### `get_reporting_exceptions` (~121 tokens)

Explains why parent/ownership data may be missing for an entity. USE WHEN: "why no parent info?", "reporting exceptions", "missing ownership data". Returns list of Level 2 exceptions, each with type (NON_CONSOLIDATING, NO_KNOWN_PERSON, NATURAL_PERSONS, NON_PUBLIC), category, and reference entity. Empty list when entity has no exceptions (parent data is complete). FAILS WHEN: LEI format invalid (must be 20 alphanumeric chars).

Input parameters:

- `lei` (string, required): LEI code

### `lei_lookup` (~147 tokens)

Get full details for a specific LEI code (legal name, address, jurisdiction, status, managing LOU, renewal dates). USE WHEN: "look up LEI", "LEI details", "who is HWUPKR0MPOU8FGXBT394?" For validating format and status only, use validate_lei. For multiple LEIs at once, use batch_lei_lookup. FAILS WHEN: LEI is not exactly 20 alphanumeric characters (fix format and retry), LEI not found in GLEIF database (entity may not have an LEI; try search_entity by name instead).

Input parameters:

- `lei` (string, required): 20-character LEI code

### `list_lei_issuers` (~79 tokens)

List all LEI issuers (Local Operating Units / LOUs) worldwide. USE WHEN: "show all LOUs", "which organizations issue LEIs?", "LEI issuer directory". Returns all issuers with name, country, status, and sponsored LEI count. For one specific issuer, use get_lei_issuer.

### `search_by_bic` (~139 tokens)

Find a bank's LEI from its BIC/SWIFT code (8 or 11 characters). USE WHEN: "find LEI from BIC", "BIC to LEI", "SWIFT code lookup", user provides a BIC code. Returns matching entity with LEI, legal name, country, and registration status. FAILS WHEN: BIC is not 8 or 11 characters (fix input), no entity mapped to this BIC (not all banks have LEIs; try search_entity with the bank name instead).

Input parameters:

- `bic` (string, required): BIC/SWIFT code (8 or 11 chars)

### `search_by_country` (~132 tokens)

List entities registered in a specific country. USE WHEN: "companies in Germany", "LEIs from US", "entities in country X". Pass ISO 2-letter code (US, GB, DE). Returns entity list with LEI, legal name, and status for each. Paginated. FAILS WHEN: country code is not a 2-letter ISO 3166-1 alpha-2 code (use "US" not "USA", "GB" not "UK").

Input parameters:

- `country` (string, required): 2-letter ISO country code
- `limit` (integer): Max results (default 20)

### `search_by_isin` (~112 tokens)

Find the issuer's LEI from a securities ISIN code (12 characters). USE WHEN: "who issued ISIN US0378331005?", "ISIN to LEI", user provides an ISIN. Returns issuer entity with LEI, legal name, country, and registration status. FAILS WHEN: ISIN is not 12 characters (fix input), no issuer found for this ISIN (some securities lack LEI mapping).

Input parameters:

- `isin` (string, required): 12-character ISIN code

### `search_entity` (~125 tokens)

Search for legal entities by name with fuzzy matching and pagination. For quick name suggestions, use autocomplete instead.

USE WHEN: "find company X", "search for X", "look up company X"

FAILS WHEN: no results found (try autocomplete for name suggestions, or check spelling; fuzzy matching is on by default).

Input parameters:

- `fuzzy` (boolean): Use fuzzy matching (default true)
- `limit` (integer): Max results per page (default 20)
- `page` (integer): Page number (default 1)
- `query` (string, required): Company name to search

### `validate_lei` (~110 tokens)

Check if an LEI code is valid and active. USE WHEN: "is this LEI valid?", "verify LEI", "check LEI format". Performs format (20 chars), check digit (ISO 17442), and database status checks. For full entity details, use lei_lookup instead. NOTE: Never returns an error for invalid LEIs; returns valid=false with a reason message instead. Safe to call on untrusted input.

Input parameters:

- `lei` (string, required): LEI code to validate
