Search AtCoder problems and fetch public problem statements through MCP.
一個非官方的 AtCoder MCP 伺服器,讓助理查找並取得公開的歷屆競賽題目敘述。
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。
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/io.github.ketherworks%2Fatcoder/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。把它新增到你客戶端的 mcpServers 設定中。

}Find and read past AtCoder problems through MCP, locally or over hosted HTTP.
Add the hosted server to your MCP configuration:
The endpoint accepts anonymous read requests. It does not need an API key, Cookie, or judge account.
Then ask:
Requires Node.js 22 or newer.
MCP client configuration from a source checkout:
Tagged GitHub releases attach a standalone npm tarball.
https://api.ksrnyx.top/oj-mcp/atcoder/mcpio.github.ketherworks/atcoder, described by server.jsonoj_healthThis standalone release is generated from the reviewed Competitive Programming MCP source. The release package bundles the shared OJ contract implementation, so its runtime does not depend on unpublished workspace packages.
Do not use this server during ongoing ABC, ARC, or AGC contests. AtCoder's current generative-AI rules generally prohibit that use. This project is intended for practice with past problems. It is unofficial and is not affiliated with or endorsed by AtCoder Inc. Problem content remains subject to the AtCoder Terms of Use.
The server exposes no run or submit tool. It accepts no judge account credentials. See SECURITY.md for the security boundary and PROVENANCE.md for the canonical source revision.
Adapter source code is MIT licensed. Judge problem content and trademarks are not relicensed by this repository.
