Otskit tools (6, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • create_timestampwrite action

    Stamps a SHA-256 hash against public OpenTimestamps calendars. IMPORTANT: the digest is sent to external calendar servers (alice.btc, bob.btc, finney, catallaxy).

  • inspect_timestamp

    Inspects a stored proof file without network calls. Returns calendar_attestations (promises from OTS servers, NOT Bitcoin confirmation) and bitcoin_attestations (actual Bitcoin blocks). A stamp is only truly confirmed when bitcoin_attestations > 0 and bitcoin_confirmed is true.

  • list_pending

    Lists stamp records with status and retry info.

  • upgrade_timestamp

    Checks if a pending stamp has been confirmed in Bitcoin. Use the id returned by create_timestamp.

  • verify_timestamp

    Verifies a stamp against Bitcoin. Does NOT affirm document authorship or truth \u2014 only proves the hash existed before a given Bitcoin block.

  • watch

    Opens a new terminal window that monitors pending stamps in real-time, polling at the given interval. The window stays open so the user can watch progress.

Install Otskit in Claude Code, Cursor or VS Code

Runs npx -y @otskit/mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Otskit repository's README, as published. We do not edit it. Read it on GitHub

@otskit/mcp

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

npm install -g @otskit/mcp

Agent setup

ots-mcp setup claude        # Claude Desktop
ots-mcp setup claude-code   # Claude Code CLI
ots-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.
