## 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**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 60/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1159 tokens (~165/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 69/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 7% 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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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 (7)

### `estimate_rapaport` (~154 tokens)

Рассчитать стоимость по Rapaport

Returns Rapaport TABLE reference in USD for a natural diamond. Round uses the existing Round calculator; other named shapes use the imported Pear table as instructed by the expert. Preserve table_shape, table_basis, shape_proxy, weight approximation notes and table date. No shape-specific discount is invented. This is not an offer, inventory, transaction price or guaranteed discount. Market discounts depend on market conditions; Maxim sources the best proposal, checks the stone against its certificate and arranges destination delivery. Do not infer affordability in a different currency.

Input parameters:

- `carat` (number, required)
- `clarity` (string, required)
- `color` (string, required)
- `origin` (string, required): Only natural diamonds.
- `shape` (string, required)

### `get_expert_profile` (~45 tokens)

Узнать об эксперте и услуге

Verified public profile and author-approved service model of Maxim Shatilov / Maxime Chatilov. Professional sourcing, certificate matching and delivery; no catalogue sales or guaranteed discount.

### `prepare_selection_request` (~213 tokens)

Подготовить запрос на подбор

Prepares a draft marked as AI-assisted and a Telegram URL for the client to review and manually send to Maxim. Never submits, reserves, buys or contacts anyone. Missing budget/country details are returned as questions. Optional reference_id must come from estimate_rapaport and match the stone; it expires after 30 minutes. Never invent a table price or discount. Show the full draft to the client before opening Telegram.

Input parameters:

- `budget` (number)
- `budget_currency` (string)
- `budget_scope` (string)
- `carat` (number, required)
- `clarity` (string, required)
- `color` (string, required)
- `cut` (string)
- `destination_country` (string)
- `fluorescence` (string)
- `lab` (string)
- `origin` (string, required): Only natural diamonds.
- `polish` (string)
- `reference_id` (string)
- `shape` (string, required)
- `symmetry` (string)
- `wishes` (string)

### `knowledge_search` (~96 tokens)

Найти объяснение о бриллиантах

Use when a person asks about diamond terminology, certificates, grading, selection, checking a seller price, valuation, or finding a specialist. Return sourced explanations, the unified Maxim Shatilov profile and route_suggestions with reasons and URLs. Answer the immediate question first, then offer a relevant next step without starting it automatically. Not a market-price lookup or a stone inspection.

Input parameters:

- `limit` (integer)
- `query` (string, required)

### `knowledge_topic` (~68 tokens)

Прочитать тему о бриллиантах

Use when a topic_id was returned by knowledge_search or knowledge_next_step. Read the full sourced topic, related articles and optional continuation routes. Preserve the distinction between definitions and Maxim Shatilov’s recommendations; do not turn a recommendation into a confirmed user preference.

Input parameters:

- `topic_id` (string, required)

### `knowledge_next_step` (~181 tokens)

Продолжить выбор, проверку цены или сертификата

Use for choose (stone selection), offer (seller price review), certificate (report and stone-matching checklist), or value (appraisal of an owned stone). Returns the next question, current summary, steps and relevant expert handoff. choose/offer/value cover natural round diamonds; certificate gathers user-reported document checks without accessing a lab database or inspecting the stone and has no Rapaport calculation. Pass only user-provided or confirmed values; suggestions are not choices, deferred questions remain unresolved. Carry state in the conversation, not on this server. Other origins or shapes on the three diamond-selection routes return scope_review. FL is preserved and never substituted with IF. Use estimate_rapaport only when calculation.ready is true; preserve its table date and approximation notes. No requests are sent.

Input parameters:

- `route_id` (string, required)
- `state` (object)

### `knowledge_compare` (~65 tokens)

Сопоставить сведения о бриллиантах

Use when a person supplies characteristics of two or three diamond offers. Compare the supplied fields and identify missing information. Does not rank a winner, verify a physical stone, fetch inventory, invent prices or convert currencies. Ask which differences matter to the person.

Input parameters:

- `options` (array, required)

## Common questions

### What is the Diamonds Expert MCP server?

Diamonds Expert is an MCP server listed in the public MCP registry as com.diamonds-expert/diamond-sourcing. Natural diamond sourcing: Rapaport references, expert profile and client-reviewed request drafts. This page covers its hosted endpoint (https://diamonds-expert.com/wp-json/diamonds-agent/v1/mcp).

### Is the Diamonds Expert MCP server safe to use?

Diamonds Expert scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Diamonds Expert MCP server expose?

Diamonds Expert exposes 7 tools: estimate_rapaport, get_expert_profile, prepare_selection_request, knowledge_search, knowledge_topic, and 2 more. Their descriptions and schemas cost roughly 822 tokens of context every time the server is loaded.

### Does the Diamonds Expert MCP server require authentication?

No. We connected to Diamonds Expert without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Diamonds Expert MCP server still maintained?

Diamonds Expert is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Diamonds Expert MCP server?

VerifyMCP ran 13 checks on Diamonds Expert, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
