概览

AI 生成的概览

本地 MCP 服务器，让 AI 助手用 OpenTimestamps 为文件或 SHA-256 哈希打时间戳、查询比特币确认并验证证明。

可以做什么
将 SHA-256 哈希或本地文件提交到公共 OpenTimestamps 日历打时间戳，并在本地保存证明。查询待确认时间戳的比特币确认状态并进行升级。对照比特币区块链验证已存时间戳或外部 .ots 证明文件。离线检查已存证明、按状态列出时间戳，并计算本地文件的 SHA-256 哈希。
适用场景
适合需要助手证明某文档或哈希在某个比特币区块之前已存在，或在对话中跟踪和验证 OpenTimestamps 证明、而不使用命令行的场景。
运行要求
以本地进程运行，通过 npm 包 @otskit/mcp 安装，需要 Node.js 20 或更高版本。无需 API 密钥。需要访问公共 OpenTimestamps 日历的网络连接，并在用户主目录下的本地目录写入数据。
安装前请注意
打时间戳会把文件的 SHA-256 哈希发送到公共 OpenTimestamps 日历，哈希因此对第三方可见。证明在比特币确认前一直处于待确认状态，可能耗时数小时。服务器会写入本地 SQLite 数据库，安装配置时可能修改代理配置文件并保留备份。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Otskit Mcp，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

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.

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.
