遠端 MCP 伺服器，讓助理以唯讀方式存取 Orbuc 的穩定幣市值與比特幣機構持倉資料集。
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.xOrbuc%2Forbuc/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。

Orbuc is a digital asset research and investment firm. Orbuc produces its own data, tracking two core datasets independently — no third-party aggregators:
Stablecoin Market Cap — direct on-chain totalSupply() RPC calls across 19 blockchain networks covering 13 stablecoins (USDT, USDC, USDS, DAI, USDe, FDUSD, PYUSD, USD1, BUIDL, BUIDL-I, crvUSD, GHO, FRAX). Updated daily at 03:00 UTC.
Bitcoin Institutional Holdings — compiled from SEC EDGAR 8-K filings, on-chain Etherscan data, and verified public disclosures across 6 segments (ETF funds, public companies, governments, private companies, DeFi/wrapped BTC, exchanges & custodians). Updated daily at 02:00 UTC.
