## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 14 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 43/100
  - AI-judged instruction clarity (poor).
  - Tool/resource definitions use about 879 tokens (~62/item across 14 items; 14 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## 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.

## MCP tools (14)

### `resolve_gtin` (~36 tokens)

Resolve a GTIN to its procurement readiness signal. Zero-pads input to 14 digits.

Input parameters:

- `gtin` (string, required)

### `check_eligibility` (~49 tokens)

Check whether a GTIN can ship to a specific retailer banner in a country.

Input parameters:

- `scope_id`

### `list_nodes` (~51 tokens)

The 49 sovereign nodes (the spine) — each with its GS1 GTIN and CLEAN per-node
maker (supply) and retailer (demand) counts (separate subqueries, never summed).

### `resolve_node` (~37 tokens)

Resolve one node: its GS1 license + its makers (supply) + its retailers (demand).

Input parameters:

- `code` (string, required)

### `find_makers` (~60 tokens)

Global cross-node maker (supply) search. Filter by segment / region / node / has_website.

as two separate counts (never summed), plus the same-node potential bridge pairs.

Input parameters:

- `code` (string, required)

### `list_sku_types` (~52 tokens)

SPARKS taxonomy: the 84 standing BPC product-type codes the graph is structured
on. Validate a type against this before a typed query. (BRAND is a tier, not a type.)

### `list_brands_by_node` (~57 tokens)

SPARKS depth surface: the distinct brands SPARKS covers in a sovereign market.
Answers 'what brands do you know in [node]'. Coverage only — no pack/size values.

Input parameters:

- `node` (string, required)

### `get_kernel` (~98 tokens)

SPARKS completeness tier for a brand in a market:
  100 = resolvable (a real pack/size record is held) . 8 = registered (brand known,
  pack/size pending) . 'floor' = STANDARD default (no brand-specific record).
Returns the stored tier flag — do NOT compute a score. Never returns a pack/size.

Input parameters:

- `brand` (string, required)
- `node` (string, required)

### `resolve_sparks` (~112 tokens)

Two-branch SPARKS resolver (zero-pads GTIN to 14).
  Branch A  GSC Territory/License GTIN (990832300xxx) -> FULL license record (public).
  Branch B  any third-party BPC GTIN -> GATED proof {recognized, region_node,
            kernel_available}; the pack/size VALUE is NEVER returned. Route to Navigator.
Brand match is fail-closed (normalized exact match); uncertainty -> recognized:false.

Input parameters:

- `gtin` (string, required)
