Verifiable physical randomness from cosmic-ray detections. Free beacon, paid signed decisions.
遠端 MCP 伺服器，以宇宙射線偵測提供可驗證隨機性：免費共用信標，以及付費的簽章承諾－揭露決策。
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/dev.costheta%2Fcostheta/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。

}Public verifier for costheta decision certificates.
Verifies: the canonical hash of the certificate body, the Ed25519 signature (RFC 8032) and the ML-DSA signature (FIPS 204), against the public keys published at costheta.dev/keys.
Code lands here shortly. The certificate format (v0.3) is specified in the federation proposal: https://github.com/costhetadev/federation-proposal

costheta random
Free public random outcome anchored to the latest signed cosmic-ray coincidence pulse. This is a shared beacon: every caller sees the same latest signed pulse until the next muon arrives. For private commitments and retry-safe paid certificates, use costheta_decide.
