## 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 2026-11-05.

- **Endpoint Security**: 57/100
  - 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 2 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 297 tokens (~148/item across 2 items; 2 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `analyze_barcode` (~93 tokens)

Validate and analyze a single EAN-8, UPC-A, EAN-13, or GTIN-14 barcode. Checks the GTIN check digit, detects common missing check digits, preserves leading zeros, safely removes spaces and hyphens, and returns GTIN-14 normalization when possible. Price: $0.001 USDC per call.

Input parameters:

- `barcode` (string, required): Barcode value to validate and analyze.

### `analyze_barcode_batch` (~204 tokens)

Validate and analyze up to 100,000 EAN-8, UPC-A, EAN-13, or GTIN-14 barcodes in one request. Supports full results, errors-only results, aggregate summaries, duplicate detection, optional deduplication, selective filtering by validity, barcode type, and validation error type, and configurable result limits. Price: $0.003 USDC per call.

Input parameters:

- `barcodes` (array, required): Barcode values to validate and analyze.
- `chunkSize` (integer): Internal processing chunk size. Defaults to 1,000.
- `deduplicate` (boolean): Enable duplicate-result caching during processing.
- `filter` (object): Optional advanced result filter. Filters affect returned individual records while aggregate statistics still describe the entire batch.
- `maxResults` (integer): Maximum number of individual results returned. Defaults to 10,000 and cannot exceed 50,000.
- `mode` (string): Output mode. Defaults to full.
