Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 2798 ms.

  • Pass
    Valid handshake

    protocolVersion 2024-11-05, serverInfo.name cvin.

  • Pass
    Lists tools

    tools/list returned 18 tools.

  • Fail
    Current protocol

    Negotiated 2024-11-05. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 2798 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 2798 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    19 of 28 parameters have a description (68%). The bar is 80%.

  • Fail
    Safety hints

    18 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass
    Recently updated

    Updated 2026-11-03T20:04:33.117052Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

cvin_buy_key

自助购买风控订阅 API 密钥（30 天有效期）：history / verify / watch / 报告端点全部直通，不再按次付费。$10.00（x402）。适合需要批量或高频核验的 Agent。

Discovered
cvin_clauses

取合同条款模板（采购订单 / 租赁 / 抵押担保 / 保险 / RWA 入池 / 尽调），中英双语，可直接粘贴进合同。永久免费，复制与引用无需署名。

Discovered
cvin_encode

由厂商/型号/形态/显存/序列号计算 CVIN（序列号不出本机：仅上传哈希后的结果参与登记）。免费。

Discovered
cvin_events

拉取结构化事件流：失联、休眠、重复抵押、价格暴跌、跨地区流转等。支持 since 增量拉取。永久免费——事件流是地基层。

Discovered
cvin_governance

治理结构：规范委员会三层分权、7 席构成（现全部空缺）、表决门槛、发起方交权清单、RFC 提案与公示期。redlines=true 时附带六条红线的可复算判定。免费。

Discovered
cvin_history

返回该 CVIN 的完整观测历史（含哈希链），用于重复抵押与违约史核查。按次计费 $0.05（x402）。

Discovered
cvin_identity

查询某 CVIN 的身份级别（L0 挂牌指纹 / L1 序列号可观测 / L2 硬件信任根）、该级别能断言与不能断言什么、以及升到下一级的做法。免费。

Discovered
cvin_lookup

万能查询：接受 CVIN、GPU 序列号、平台链接/host id、机房资产标签、发票号、型号名——不需要用户先学会 CVIN。返回命中的 CVIN 列表、命中理由与下一步。免费。

Discovered
cvin_market_models

设备级真实挂牌行情快照：每个 GPU 型号当前有多少台真实机器在某平台挂牌、单卡小时价的 P10/中位/P90、平台与地区分布、快照时间。只含设备级挂牌（vast.ai / Clore.ai，身份 L0），不含型号级报价，两者不得相加。报价是挂牌价不是成交价，极值不裁剪。免费。

Discovered
cvin_market_price

查询某 GPU 型号的租赁行情：按平台返回最新报价（价格/地区/库存/观测时间）。输入 "nv.h100" 或裸型号 "h100"/"rtx4090"（自动匹配厂商前缀）。免费。型号级行情是供给报价，不指向具体设备；要核验某台具体设备请用 cvin_resolve / cvin_history。

Discovered
cvin_permits

判断某个身份级别能否用于某个用途（如「抵押登记」「保险核保」「资产池入池」）。返回 {allowed, level, upgrade_to}。免费——这一层让「L0 不能抵押」由机器把关而不是靠人记得。

Discovered
cvin_provenance

数据出处与合成数据占比：真实/合成各多少、设备级与型号级分开算、来自哪些源、离「合成占比 ≤10%」还差多少条真实观测。引用登记表统计前应先查这一项。免费。

Discovered
cvin_report

签发单台设备的正式核验报告（报告编号 + ed25519 签名 + 固定内容哈希，可留档可独立验签），供放款 / 承保 / 承租决策留档。按份计费 $2.00（x402）。

Discovered
cvin_risk_signals

风险信号聚合：身份级别分布、活跃度分布、在押与重复抵押计数、事件计数。事件数未达 200 阈值前只输出计数，不输出比率（先计数后比率）。免费。
