Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "rel-time": {
      "command": "npx",
      "args": [
        "-y",
        "@rel-time/mcp-server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add rel-time -- npx -y @rel-time/mcp-server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "rel-time": {
      "command": "npx",
      "args": [
        "-y",
        "@rel-time/mcp-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "rel-time": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@rel-time/mcp-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Rel-Time Protocol (Bitcoin & VDF Provenance) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.14) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

`@rel-time/mcp-server` — Official Rel-Time MCP Server

Official Model Context Protocol (MCP) server for [Rel-Time](https://rel-time.com) — enabling Claude Desktop, Cursor, Windsurf, and Google Antigravity agents to:

Hash local files with 100% Zero-Knowledge (your file bytes never leave your computer).
Execute both Anonymous & Biometric (Passkey) Anchors (SHA256(File_Hash + Passkey_PubKey)) using TouchID, FaceID, or YubiKey via https://rel-time.com/mcp-passkey.
Anchor SHA-256 hashes to the Bitcoin Timechain & Rel-Time VDF (POST /v1/anchor).
Generate & overlay 64-ray Sun-Stamps onto PDFs and Images (reltime-stamped- .pdf / .png).
Verify Bitcoin block settlement & Merkle proofs (GET /v1/proof/{hash}).
Self-provision or Reload all 4 Rel-Time Tiers via Bitcoin Lightning or Stripe Card (Universal Anchor $3, Agent Launch Pack $5 / 25, Autonomous Agents $50 / 500, and Rel-Time Superhighway $399 / 5,000).
Run a Superhighway Cryptographic Audit Trail & Local Folder Integrity Check (reltime_audit_trail), generating an interactive HTML Audit Dashboard with Corporate Hardware Passkey (signer_public_key) attribution and Bitcoin block verification.

Quick Setup (Claude Desktop / Claude Code / Cursor / Windsurf / Antigravity)

Add the following to your .mcp.json, claude_desktop_config.json, or .cursor/mcp.json (no API key or .zshrc environment variables needed to start!):

"mcpServers": { "rel-time": { "command": "npx", "args": ["-y", "@rel-time/mcp-server@latest"] } } }

When you start a fresh chat and ask to anchor a file or provision a key, @rel-time/mcp-server automatically prompts your agent to ask which tier and payment method (Bitcoin Lightning or Stripe Card) you want first:

Universal Anchor (`pack: "universal"`, `$3 / anchor`): Priority 10-Minute Bitcoin Queue · Standard Mode (Data Integrity + Biometric or Anonymous).
Agent Launch Pack (`pack: "launch"`, `$5 / 25 Hashes`, max 3 per key): Priority 10-Minute Bitcoin Queue · Standard Mode · Includes 64-Ray Sun-Stamp, 1-Click Stamped Copy (.PDF/.PNG), 4-Plate Certificate, and .JSON Doomsday Proof.
Autonomous Agents (`pack: "standard"`, `$50 / 500 Hashes`): Dynamic 6-Hour Batch Queue · Supports both Temporal Mode (T_index sub-second VDF sequencing) and Standard Mode · Reloadable anytime (+500 credits / $50).
Rel-Time Superhighway (`pack: "enterprise"`, `$399 / 5,000 Hashes`): Priority 10-Minute Bitcoin Queue · Temporal Mode (T_index) + Standard Mode + Data Integrity Audit & Instant Tamper Detection.

Once paid via Lightning or Stripe (or if you pass an existing rel_key_... key), the MCP server automatically saves your API key to ~/.reltime/api_key.json (0600 permissions) — no app restart or .zshrc edits required.

Available MCP Tools

Tool Name	Requires Key?	What It Does
`reltime_anchor_file`	Yes	Computes the SHA-256 hash of a local file on your machine (0 bytes uploaded), supports `biometric: true` for Biometric Anchors (TouchID/FaceID/YubiKey), anchors via `POST /v1/anchor`, saves `reltime-stamp- .svg`, `reltime-certificate- .html`, and `reltime-doomsday-proof- .json`, and automatically outputs a clickable Stamped Copy (`reltime-stamped- .pdf` or `.png`).
`reltime_anchor_folder`	Yes	Bulk folder anchoring (10 to 5,000+ files in one call): Hashes all files in a local folder 100% locally, supports `biometric: true` (Passkey) or Anonymous mode, automatically skips already-anchored files (safe to resume), and keeps your directory clean by storing per-file Doomsday Proofs inside `/_reltime_proofs/` plus a master `reltime-batch-manifest.json`.
`reltime_audit_trail`	Yes	Fetches the account's chronological anchor ledger (`GET /v1/account/history`), aggregates Bitcoin block settlements, VDF `T_index` ticks, and Corporate Hardware Passkey (`signer_public_key`) signatures, optionally verifies a local file or entire folder bit-for-bit (`verify_local_path`), and spins up a self-contained interactive HTML Audit Report (`reltime-audit-report-*.html`) in your browser.
`reltime_link_passkey`	No	Opens `https://rel-time.com/mcp-passkey` in the system browser so the user can touch TouchID / FaceID / YubiKey once, saving `{ public_key_hex, passkey_signature }` to `~/.reltime/passkey.json` for seamless Biometric Anchors.
`reltime_stamp_file`	No	Overlays the authentic 64-ray Sun-Stamp onto the bottom-right corner of any local PDF or Image (`.png`, `.jpg`, `.jpeg`, `.webp`, `.gif`) 100% locally.
`reltime_anchor_hash`	Yes	Anchors any 64-char hex SHA-256 hash in `standard` (10-min Express / Integrity) or `temporal` (VDF sequence ordering) mode.
`reltime_get_sun_stamp`	No	Fetches the deterministic 64-ray SVG Sun-Stamp (`GET /v1/stamp/{hash}`) and returns ready-to-paste Markdown/HTML badge snippets.
`reltime_check_proof`	No	Queries `GET /v1/proof/{hash}` for Bitcoin TXID, Block Height, UTC Timestamp, and Merkle inclusion path, and optionally saves/updates the `.json` Doomsday Proof receipt on disk.
`reltime_account_status`	Yes	Checks remaining Hash Credits and tier status (`GET /v1/account`).
`reltime_provision_agent_key`	No	Provisions or reloads any of the 4 Rel-Time Tiers (`universal` `$3`, `launch` `$5/25`, `standard` `$50/500`, `enterprise` `$399/5,000`) via Bitcoin Lightning or Stripe Card.
