Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
AI agents discover, acquire, and re-serve tokenised web content via the $402 protocol
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
PATH402_API_URL, PATH402_DEFAULT_BUDGET, PATH402_WALLET_WIFValues marked secret are keys to your account. Never share them or paste them into a chat.

Turn AI agents into autonomous economic actors. Run a $402 network node.
This package includes:
npm install -g path402
path402d start
This starts a $402 network node that:
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
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:
No anonymous propaganda dealers running underground BitTorrent clients with no accountability.

Add to your claude_desktop_config.json:
{
"mcpServers": { "path402": { "command": "npx", "args": ["path402"], "env": { "PATH402_API_URL": "https://path402.com", "PATH402_DEFAULT_BUDGET": "10000" } } } }
You: "Discover what's available at $example.com"
Claude: [Uses path402_discover to probe the $address] Found 3 nested tokens:
You: "Evaluate if $example.com/$blog is worth acquiring"
Claude: [Uses path402_evaluate and path402_economics] ROI Analysis:
You: "Acquire 10 tokens"
Claude: [Uses path402_acquire] Acquired 10 $example.com/$blog tokens Total cost: 5,000 sats New balance: 10 tokens
$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 is determined by remaining treasury, not speculation:
price = base_price / √(treasury_remaining + 1)
| Treasury | Price | % Sold |
|---|---|---|
| 500M | 10 sats | 0% |
| 100M | 22 sats | 80% |
| 10M | 71 sats | 98% |
| 1M | 224 sats | 99.8% |
| 1K | 7,072 sats | 99.9998% |
Key insight: Early buyers always get better prices. This creates natural incentives for discovery and early adoption.
Agents can become economically self-sustaining:
The ascending bonding curve mathematically guarantees that early acquirers can achieve positive ROI through serving.

Agent explores the $402 namespace, discovering valuable content:
1. path402_batch_discover(["$news.com", "$research.org", "$data.io"])
Agent manages API access for a team:
1. path402_acquire("$api.service.com", 1000)
Agent gathers information from paywalled sources:
1. path402_discover() research databases
Agent that pays for itself:
1. path402_acquire() tokens at low prices
| Network | Status | Assets |
|---|---|---|
| BSV | Primary | BSV, BSV-20 tokens |
| Base | Supported | USDC, ETH |
| Solana | Supported | USDC, SOL |
| Ethereum | Supported | USDC, ETH, USDT |
BSV is the settlement layer. Payments from other chains are verified and inscribed on BSV for permanent proof.
