## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: search_knowledge_base (destructiveHint, idempotentHint); get_company_info (destructiveHint, idempotentHint, openWorldHint); create_checkout_link (idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 4,747 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

## Tools (8)

- `create_checkout_link`: Assemble a cart and get a Stripe-hosted checkout URL the customer opens to pay; no card data passes through the agent. Item ids come from the search tools (`diamond:<report>`, `setting:<slug>`, `jewelry:<slug>`); a complete ring is one setting plus one diamond. Needs the shipping address (prices tax and shipping into the link). Expires after 24 hours. No credential needed. Without a production credential this tool runs in the sandbox: the link is simulated and no Stripe session is created. Pass `env: "production"` when the customer actually wants to buy — that returns a live, payable link.
- `get_company_info`: Contact details, showroom address and hours, how consultations work, and what Ada Diamonds sells. Use this to answer questions about the business rather than about a product.
- `read_article`: Fetch the full markdown text of one Ada Diamonds knowledge base article by slug. Use search_knowledge_base first if you don't know the slug.
- `request_consultation`: Submit a consultation request on the customer's behalf. Requires the `appointments:write` scope, which the customer grants through Ada's OAuth authorization flow — this tool cannot be used without their explicit approval.
- `search_diamonds`: Search Ada Diamonds' live loose lab grown diamond inventory by shape, carat weight, price, color, clarity, and cut. Returns currently available stones with their grading report numbers and product URLs. Use this for any question about what diamond a budget can buy. MCP Apps-enabled: hosts that support MCP Apps render the results as an interactive card grid.
- `search_engagement_rings`: Search Ada Diamonds' engagement ring settings by center-stone shape, style, and setting price. Setting prices exclude the center diamond — pair with search_diamonds to quote a complete ring. MCP Apps-enabled: hosts that support MCP Apps render the results as an interactive card grid.
- `search_jewelry`: Search Ada Diamonds' fine jewelry — wedding bands, earrings, necklaces, bracelets, and fashion rings — by category, type, diamond shape, and price. MCP Apps-enabled: hosts that support MCP Apps render the results as an interactive card grid.
- `search_knowledge_base`: Search Ada Diamonds' published guides on lab grown diamonds — the 4Cs, CVD vs HPHT growth, shape guides, certification, and buying advice. Returns article summaries and markdown URLs. Use read_article to get an article's full text.
