概覽

AI 產生的概覽

核查 AI 回答中引用的識別碼是否真實存在：向核發這些識別碼的註冊機構查詢，並產出附簽章的报告。

可以做什麼
  • 向核發機構核查被引用的識別碼（DOI、PubMed、arXiv、ORCID、ROR、ISBN、LEI、ISIN、CUSIP、SEC CIK、EIN、NPI、英國公司編號、網域等）
  • 每個識別碼回傳四種狀態之一：確認屬實、確認不實、無法判定、無法連線，並附上未核查清單與原因
  • 產出附簽章的報告，含報告編號、PDF、註冊機構查詢紀錄及每次回覆的 SHA-256
  • 提供可分享的報告連結，任何人開啟後都能即時重新核查
適用情境
適合在依賴、發布或轉寄帶引用的 AI 回答之前，確認所引識別碼確實存在且已登記。它只驗證登記情形，不判斷文獻是否支持某項主張。
執行需求
遠端 MCP 端點，使用 streamable HTTP 與 OAuth 登入；首次連線會自動建立免費 Metis 帳號。不需本機執行環境、套件或環境變數。超出每月免費核查額度後需付費方案。
安裝前請注意
OAuth 登入會建立與該服務綁定的帳號；免費額度為每月 5 次核查，Pro 與 Team 方案需付費。報告可透過連結分享，任何取得連結的人都能查看。服務只保存識別碼、位置與雜湊而不保存原文，但送出的識別碼會傳給第三方註冊機構。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Metis Check，將其新增到工作區。
  2. 連接 所需的 憑證。它們會被私密儲存，絕不會在公開頁面上展示。
  3. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/com.metisfoundry.check-api%2Fmetis-check/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

Metis Check

The check every cited AI answer needs before you rely on it. A citation that looks complete and points to nothing costs a correction, a retraction or a sanction. Metis Check asks the registries that issue each identifier whether it exists and what it says. DOI, PubMed, arXiv, ORCID, ROR, ISBN, LEI, ISIN, CUSIP, SEC CIK, EIN, NPI, UK company numbers, domains and more. Each identifier comes back in exactly one of four states: settled true, settled false, not decidable (a person decides) or unreachable (a delay, not evidence). Every check ends in a signed report with its own id, a PDF and a recheck button anyone can press.

By Metis Foundry. One account covers ChatGPT, Codex, Claude, Claude Code, Cursor and VS Code. Every account starts with 5 checks a month; plans.

[A Metis Check report]

A real report: three identifiers settled true, one settled false. Open it and press Recheck.

Try it in one click

The prompt asks Metis Check to check four references, one of them invented. The invented one comes back settled false, with the registry that said so.

What you get

  • Four states, nothing hidden: settled true, settled false, not decidable, unreachable, and a not-checked list with the reason for each.
  • A report that rechecks without Metis: every line carries the registry query and the SHA-256 of the registry's answer; signed JSON and a PDF.
  • Shareable: anyone with the link can open the report and press Recheck; the registries are asked again, live.
  • Private: passages are never stored, only the identifiers, their positions and a hash. Metis never asks for conversation history.
  • Honest scope: Metis Check establishes that an identifier is registered and what the registry says. It does not decide whether a paper supports a claim.

Plans

Free: 5 checks a month. Pro: $29 a month (or $276 a year), 2,000 checks, case law included. Team: $249 a month (or $2,388 a year), 15,000 checks, 5 seats. Checks that cannot be settled cost nothing. Details: https://check-api.metisfoundry.com/check/plans
