概覽

AI 產生的概覽

本機 MCP 伺服器，讓 AI 助理用 OpenTimestamps 為檔案或 SHA-256 雜湊打時間戳、查詢比特幣確認並驗證證明。

可以做什麼
將 SHA-256 雜湊或本機檔案提交到公開 OpenTimestamps 日曆打時間戳，並在本機保存證明。查詢待確認時間戳的比特幣確認狀態並進行升級。對照比特幣區塊鏈驗證已存時間戳或外部 .ots 證明檔案。離線檢查已存證明、依狀態列出時間戳，並計算本機檔案的 SHA-256 雜湊。
適用情境
適合需要助理證明某文件或雜湊在某個比特幣區塊之前已存在，或在對話中追蹤與驗證 OpenTimestamps 證明、而不使用命令列的情境。
執行需求
以本機程序執行，透過 npm 套件 @otskit/mcp 安裝，需要 Node.js 20 或更新版本。無需 API 金鑰。需要連線至公開 OpenTimestamps 日曆的網路，並會在使用者家目錄下的本機目錄寫入資料。
安裝前請注意
打時間戳會把檔案的 SHA-256 雜湊傳送到公開 OpenTimestamps 日曆，雜湊因此對第三方可見。證明在比特幣確認前一直處於待確認狀態，可能耗時數小時。伺服器會寫入本機 SQLite 資料庫，設定時可能修改代理設定檔並保留備份。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Otskit Mcp，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

OpenTimestamps MCP server - stamp, upgrade, and verify Bitcoin timestamps via AI agents.

Exposes a set of tools to any MCP-compatible agent so it can timestamp documents, monitor confirmation status, and verify proofs against the Bitcoin blockchain - all from a conversation.

This is an independent implementation of the OpenTimestamps protocol. It is not affiliated with, endorsed by, or maintained by the OpenTimestamps project.

[OTSkit MCP server on Glama — security, license and quality rating plus download count]

Note on confirmation times: After stamping, a proof is pending until Bitcoin confirms it. Confirmations typically arrive within ~60 minutes, but can take several hours during network congestion. Use ots-mcp watch or upgrade_timestamp to monitor. A pending proof is not a failed proof.

Install

bash
npm install -g @otskit/mcp

Agent setup

bash
ots-mcp setup claude        # Claude Desktopots-mcp setup claude-code   # Claude Code CLIots-mcp setup codex         # Codex CLI

Each command writes the MCP entry into the agent's config file, makes a .bak backup if the file already exists, and skips if ots-mcp is already configured. Restart the agent afterwards to apply the changes.

CLI commands

CommandDescription
ots-mcp serveStart the MCP server (stdio transport)
ots-mcp stamp <sha256>Stamp a SHA-256 hash against Bitcoin calendars
ots-mcp upgrade <id>Check if a pending stamp has been confirmed
ots-mcp verify <id>Verify a stamp against Bitcoin
ots-mcp list [status]List stamps (pending / confirmed / failed)
ots-mcp watch [minutes]Monitor pending stamps and attempt due upgrades (default: 30 min, minimum: 15 min)
ots-mcp check-pendingRun one upgrade pass over all pending stamps
ots-mcp scheduler install|remove|statusManage OS-level scheduler for auto-upgrades
ots-mcp backup [dest]Backup the SQLite database
ots-mcp setup <claude|claude-code|codex>Configure MCP for an agent

MCP tools exposed to agents

ToolDescription
create_timestampStamp a SHA-256 hash against 4 public OTS calendars
upgrade_timestampCheck if a pending stamp has been confirmed in Bitcoin
verify_timestampVerify a stamp - proves hash existed before a given Bitcoin block
verify_external_proofVerify a whitelisted local file against its external .ots proof, without changing the local stamp store
inspect_timestampInspect a stored proof file without network calls
list_pendingList stamps with status, retry count, and filters
watchOpen a terminal window monitoring pending stamps and attempting due upgrades
hash_fileCompute the SHA-256 of a local file and return it as a 64-char hex string (no network calls)
stamp_fileCompute SHA-256 of a local file and stamp it on Bitcoin in one step

Data directory

All data is stored in ~/.ots-mcp/:

text
~/.ots-mcp/  ots-mcp.db       # SQLite database (stamps, proof files)  config.json      # Optional config overrides  ots-mcp.log      # Log file

Configuration

Create ~/.ots-mcp/config.json to override defaults:

json
{  "stamp_enabled": true,  "scheduler_interval_minutes": 30,  "retry_max_attempts": 20,  "calendar_timeout_ms": 10000,  "calendars": [    "https://alice.btc.calendar.opentimestamps.org",    "https://bob.btc.calendar.opentimestamps.org",    "https://finney.calendar.eternitywall.com",    "https://btc.calendar.catallaxy.com"  ]}

Development

bash
npm run build    # production buildnpm run dev      # watch modenpm test         # run tests

Dependencies

Requires Node.js >= 20.
