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 The release package bundles the shared OJ contract implementation, so its runtime does not depend on unpublished workspace packages.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.
