Getting Started with httpOnly() — Zero-friction PoT for Claude Desktop

[Heime-Jorgen]

Getting Started with OpenTTT httpOnly Mode

The fastest way to start generating Proof-of-Time attestations — no wallet, no ETH needed.

Install

npx @helm-protocol/ttt-mcp

Claude Desktop config

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "openttt": {
      "command": "npx",
      "args": ["-y", "@helm-protocol/ttt-mcp"],
      "env": { "TTT_MODE": "httpOnly" }
    }
  }
}

5 tools

• pot_generate — timestamped PoT attestation
• pot_verify — verify an existing proof
• pot_query — query proof history
• pot_stats — 54K+ proofs on Base Sepolia
• pot_health — check 4 HTTPS time sources (NIST, USNO, PTB, NICT)

httpOnly mode = zero gas, instant results, same cryptographic guarantees.
