## 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**: 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 3 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**: 74/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 458 tokens (~152/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - 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**: 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `search_books` (~192 tokens)

On-Demand-Books: Search Personalized Books

Search for personalized puzzle books by first name. Returns matching books with direct Shopify purchase links, cover images, and ISBNs. A typical exact match returns 9 books across 3 puzzle types (mazes, name-sudokus, word searches) and 3 difficulty levels. When no exact match exists, returns similarly-named books. Use this whenever a user is shopping for a personalized gift and knows the recipient's first name.

Input parameters:

- `name` (string, required): First name to search for personalized puzzle books (e.g. 'Susan', 'Bob'). Case-insensitive; non-letters are stripped.
- `utm_source` (string): Optional UTM source tag for marketing attribution (e.g. 'mcp.so', 'claude', 'hn'). Appended as ?utm_source=<value> to all Shopify product URLs so the seller can track which channel drove the sale. De…

### `suggest_names` (~137 tokens)

On-Demand-Books: Suggest Available Names

Suggest first names for which personalized puzzle books are likely available. Use this when a user is unsure of a spelling, wants gift-recipient ideas, or only has part of a name. Returns popular available names, optionally filtered by a case-insensitive prefix. To confirm a specific name has matching books, follow up with `search_books`.

Input parameters:

- `limit` (integer): Maximum number of suggestions to return (default 20, max 100).
- `prefix` (string): Optional name prefix to complete (e.g. 'su' -> 'Susan', 'Susie', 'Suzanne'). If omitted, returns a curated list of popular names.

### `get_book` (~129 tokens)

On-Demand-Books: Get Book by Handle

Re-resolve a single book's purchase URL, cover image, and ISBN from its Shopify product handle. Use this to refresh or re-reference a book across turns without re-running the full name search.

Input parameters:

- `handle` (string, required): Shopify product handle (as returned in the `shopify_handle` field of a `search_books` result).
- `utm_source` (string): Optional UTM source tag for marketing attribution (e.g. 'mcp.so', 'claude', 'hn'). Appended as ?utm_source=<value> to the Shopify product URL. Defaults to 'mcp'.
