Quick Install

npx -y dollar402-mcp-server

path402

Turn AI agents into autonomous economic actors. Run a $402 network node.

This package includes:

  • MCP Server — AI agent tools for Claude, GPT, etc.
  • path402d Daemon — Index tokens, serve content, earn rewards

npm version License: Open BSV


Quick Start

Installation

npm install -g path402

Run path402d Daemon

path402d start

This starts a $402 network node that:

  • INDEX — Reads BSV blockchain, tracks all $402 tokens
  • VALIDATE — Confirms token ownership before serving
  • SERVE — Delivers content to verified token holders
  • EARN — Receives $402 rewards via PoW20

path402d CLI Commands

path402d start           # Start the daemon
path402d status          # Check if running
path402d stop            # Stop the daemon
path402d config          # Show configuration
path402d mine            # Start PoW20 mining (experimental)
path402d --help          # Full help

Why Run path402d?

PoW forces operators into the open. Big nodes can't hide.

The purpose of PoW20 is NOT just to reward work—it's to force operators into visibility:

  • Computational cost → Capital investment → Scale
  • Scale → Physical presence → Regulatory visibility
  • Big nodes must identify themselves

No anonymous propaganda dealers running underground BitTorrent clients with no accountability.

Claude Desktop Integration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "path402": {
      "command": "npx",
      "args": ["path402"],
      "env": {
        "PATH402_API_URL": "https://path402.com",
        "PATH402_DEFAULT_BUDGET": "10000"
      }
    }
  }
}

First Conversation

You: "Discover what's available at $example.com"

Claude: [Uses path402_discover to probe the $address]
        Found 3 nested tokens:
        - $example.com/$blog (500 sats, 0 supply)
        - $example.com/$api (1000 sats, 0 supply)
        - $example.com/$premium (2500 sats, 0 supply)

You: "Evaluate if $example.com/$blog is worth acquiring"

Claude: [Uses path402_evaluate and path402_economics]
        ROI Analysis:
        - Current price: 500 sats
        - Breakeven: 1 serve at current rates
        - Projected ROI: 340% over 30 days
        Recommendation: ACQUIRE (high confidence)

You: "Acquire 10 tokens"

Claude: [Uses path402_acquire]
        Acquired 10 $example.com/$blog tokens
        Total cost: 5,000 sats
        New balance: 10 tokens

The $402 Protocol

What is $402?

$402 turns URL paths into tokenized markets. Any path prefixed with $ becomes an economic object:

$example.com              → Site-level token
$example.com/$api         → API access token
$example.com/$api/$premium → Premium tier token

Each token has:

  • Price curve (sqrt_decay by default)
  • Supply counter (increases with each acquisition)
  • Holder registry (who owns what)
  • Revenue distribution (issuer/facilitator split)

sqrt_decay Pricing

Price is determined by remaining treasury, not speculation:

price = base_price / √(treasury_remaining + 1)
TreasuryPrice% Sold
500M10 sats0%
100M22 sats80%
10M71 sats98%
1M224 sats99.8%
1K7,072 sats99.9998%

Key insight: Early buyers always get better prices. This creates natural incentives for discovery and early adoption.

Self-Funding Agents

Agents can become economically self-sustaining:

  1. Acquire tokens at current price
  2. Serve content to other agents/users
  3. Earn revenue from serving
  4. Reinvest profits into more tokens

The sqrt_decay model mathematically guarantees that early acquirers can achieve positive ROI through serving.

Use Cases

1. Content Discovery Agent

Agent explores the $402 namespace, discovering valuable content:

1. path402_batch_discover(["$news.com", "$research.org", "$data.io"])
2. path402_evaluate() on promising finds
3. path402_acquire() undervalued tokens
4. path402_serve() to users who request content

2. API Gateway Agent

Agent manages API access for a team:

1. path402_acquire("$api.service.com", 1000)
2. path402_wallet() to track usage
3. path402_serve() when team members need API calls
4. path402_acquire() more when balance runs low

3. Research Agent

Agent gathers information from paywalled sources:

1. path402_discover() research databases
2. path402_economics() to evaluate cost/benefit
3. path402_acquire() access to valuable sources
4. Compile research using acquired content

4. Revenue-Generating Agent

Agent that pays for itself:

1. path402_acquire() tokens at low prices
2. path402_servable() to list inventory
3. path402_serve() to other agents
4. path402_wallet() to track profits
5. Reinvest profits into more tokens
