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. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability60
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management30
- Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage69
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 7% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
estimate_rapaport Рассчитать стоимость по Rapaport ~154
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.
| Name | Type | Req | Description |
|---|---|---|---|
| carat | number | yes | – |
| clarity | string | yes | – |
| color | string | yes | – |
| origin | string | yes | Only natural diamonds. |

get_expert_profile Узнать об эксперте и услуге ~45
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
knowledge_compare Сопоставить сведения о бриллиантах ~65
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.
| Name | Type | Req | Description |
|---|---|---|---|

No output schema declared.
No examples provided.
knowledge_next_step Продолжить выбор, проверку цены или сертификата ~181
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.

No output schema declared.

knowledge_search Найти объяснение о бриллиантах ~96
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.

knowledge_topic Прочитать тему о бриллиантах ~68
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.
| Name | Type | Req | Description |

prepare_selection_request Подготовить запрос на подбор ~213
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.
