Overview

Description from the maker (original English)

Cryptographic identity, SIGIL naming, heartbeat, and passports for AI agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 0 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

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": {
    "provenonce": {
      "command": "npx",
      "args": [
        "-y",
        "@provenonce/mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add provenonce -- npx -y @provenonce/mcp

Open in Cursor

Or copy the settings yourself

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

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

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": {
    "provenonce": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@provenonce/mcp"
      ]
    }
  }
}

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 Provenonce safe?

It passed 0 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 (1.1.4) reached the registry 8 months 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?

Provenonce Skill — Give any AI agent cryptographic identity in under 60 seconds.

Add this skill to your agent and it gets:

  • A permanent cryptographic hash (identity)
  • A SIGIL (verified identity class + tier)
  • A signed Passport (verifiable offline by any third party)
  • Heartbeat (continuous liveness proof)
  • Beats proofs (evidence of computational work)
  • Lineage (full ancestry chain)

Quick Start

Claude Desktop / Claude Code

Add to ~/.claude/claude_desktop_config.json:

{

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

That's it. On first use, your agent calls provenonce_register and gets a permanent identity.

With pre-existing credentials
{

"mcpServers": { "provenonce": { "command": "npx", "args": ["-y", "@provenonce/mcp"], "env": { "PROVENONCE_API_KEY": "pvn_...", "PROVENONCE_AGENT_HASH": "0x..." } } } }

As a skill developer (earn rev share)

If you're a developer embedding this skill in your framework, include your partner ref token:

{

"env": { "PROVENONCE_SKILL_REF": "your16hextoken" } }

You earn 30% of every SIGIL purchased by agents you deploy. Register at POST /api/v1/skill/register.

The 11 Tools

ToolWhat it doesAuth needed
provenonce_registerAuto-register agent, get hash + API keyNone
provenonce_statusFull current state (SIGIL, balance, hints)Yes
provenonce_purchase_sigilBuy SIGIL, unlock heartbeat + passportYes + SOL tx
provenonce_heartbeatSubmit liveness proofYes + SOL tx
provenonce_batch_heartbeatHeartbeat multiple children in one callYes + SOL tx
provenonce_get_passportGet signed identity documentYes
provenonce_beats_proofCompute work proof, get receipt (for spawn/resync)None
provenonce_submit_beatsCompute VDF beats and credit lifetime beat countYes
provenonce_verify_agentCheck another agent's identityNone
provenonce_spawnSpawn a child agentYes
provenonce_get_lineageGet full ancestry chainNone

Usage Examples

Example 1: Register and check status

User prompt: "Register with Provenonce and show me my identity."

Expected behavior:

  • Agent calls provenonce_register with an optional name
  • Receives a permanent cryptographic hash (e.g. 0xabcd...) and API key
  • Credentials are saved to ~/.provenonce/config.json
  • Agent calls provenonce_status to display identity, balance, and next steps
  • Status response includes a _hint suggesting the agent purchase a SIGIL
Example 2: Verify another agent before trusting it

User prompt: "Check if agent 0xf7dad8f4...b6fd is legitimate."

Expected behavior:

  • Agent calls provenonce_verify_agent with the target hash
  • Returns the agent's SIGIL, identity class, tier, registration date, and liveness score
  • Agent reports whether the target has an active SIGIL and recent heartbeats
  • No authentication needed — this is a public verification endpoint
Example 3: Full lifecycle — SIGIL, heartbeat, and passport

User prompt: "Get me a SIGIL, send a heartbeat, and export my passport."

Expected behavior:

  • Agent calls provenonce_purchase_sigil without payment_tx to get fee instructions (amount in SOL + ops wallet address)
  • User sends the SOL payment and provides the transaction signature
  • Agent calls provenonce_purchase_sigil again with the payment_tx to complete the purchase
  • Agent calls provenonce_heartbeat (same payment flow) to prove liveness
  • Agent calls provenonce_get_passport to receive a cryptographically signed identity document
  • Passport can be verified offline by any third party using the Provenonce authority public key

Agent Flow

Day 1:  provenonce_register      → hash minted, credentials saved

provenonce_beats_proof → works immediately, no SIGIL needed provenonce_status → { sigil: null, _hint: "Call provenonce_purchase_sigil..." }

Day 7: provenonce_purchase_sigil → pay SOL, SIGIL issued provenonce_heartbeat → now unlocked provenonce_get_passport → signed identity doc, share with anyone provenonce_verify_agent → verify a counterparty before trusting them

Environment Variables

VariableDescriptionDefault
PROVENONCE_API_KEYAgent API key (pvn_...)Read from ~/.provenonce/config.json
PROVENONCE_AGENT_HASHAgent hash (0x...)Read from ~/.provenonce/config.json
PROVENONCE_SKILL_REFYour partner ref token (for rev share)None
PROVENONCE_REGISTRY_URLRegistry URL overridehttps://provenonce.io

Framework-Agnostic Usage

import { PROVENONCE_TOOLS } from '@provenonce/mcp/tools';

// OpenAI const tools = PROVENONCE_TOOLS.map(t => ({ type: 'function', function: t }));

// LangChain / custom — use PROVENONCE_TOOLS for schema, implement handlers yourself

Credential Storage

Credentials are stored in ~/.provenonce/config.json with chmod 600 permissions (Unix).

On Windows, use environment variables (PROVENONCE_API_KEY + PROVENONCE_AGENT_HASH) — file permissions are not enforced.

Privacy Policy

Provenonce collects the minimum data necessary to provide cryptographic identity services:

  • Data collected: Agent name (optional), cryptographic hash (generated), API key, SIGIL metadata, heartbeat timestamps, and Solana transaction signatures for payments.
  • How data is used: To maintain the agent identity registry, verify agent liveness, and issue signed passports. No data is sold to third parties.
  • Storage: Agent state is stored in Supabase (PostgreSQL). Tamper-proof timestamps are anchored on the Solana blockchain as SPL Memo transactions.
  • Third-party sharing: On-chain memos (registration, SIGIL) are publicly visible on Solana. No other data is shared with third parties.
  • Retention: Agent records persist indefinitely as part of the provenance chain. Revoked agents are marked but not deleted.
  • Contact: ops@provenonce.io
