Data Privacy & What Gets Sent#

The server requires only the tool call parameters listed below. What your MCP client actually transmits depends on the client implementation — please review your MCP client's privacy and transport settings to verify.

Specifically, each tool requires:

• get_kimchi_premium, get_global_vs_korea_divergence, get_global_vs_korea_divergence_deep: symbol parameter only (e.g., "BTC")
• get_kr_prices: symbol and exchange parameters only
• get_kr_news_kpop, get_kr_news_kpop_summary, get_kr_news_semiconductor, get_kr_news_semiconductor_summary: optional limit parameter only (1-10, default 5)
• get_arbitrage_scanner, get_exchange_alerts, get_market_movers: no parameters — server computes from cached exchange data
• get_market_read: no parameters — server fetches all data internally and runs AI analysis server-side
• get_kr_sentiment: no parameters — server combines exchange data with Korean news context and runs AI sentiment analysis server-side
• get_fx_rate, get_stablecoin_premium, get_available_symbols, check_health: no parameters

Note: Like any HTTP service, the server receives standard HTTP metadata (IP address, user-agent) as part of normal network communication.

Network calls only to: mcp.printmoneylab.com and api.printmoneylab.com

Payment Authorization (x402 Protocol)#

How x402 payment works — step by step:

1. Agent calls a paid endpoint (e.g., get_kimchi_premium)
2. Server returns HTTP 402 with price in the payment-required header
3. The MCP client or platform decides whether to pay — this is NOT automatic
4. If the client approves, it signs a USDC transfer for the exact amount on Base, Polygon, or Solana
5. Client retries with payment proof in X-PAYMENT header
6. Server verifies payment and returns data

Key points:

• Payment is NOT automatic. The agent's MCP client (e.g., xpay Smart Proxy, Claude, Cursor) controls whether to authorize payment.
• No wallet keys or credentials are stored in this skill. Payment is handled entirely by the MCP client's x402 transport layer.
• The skill cannot charge without explicit client-side authorization. The x402 protocol requires a cryptographic signature from the buyer's wallet.
• Cost per call: $0.001 (basic data) to $0.10 (AI deep analysis). No subscriptions, no hidden fees.

Receipt Verification#

Every paid response includes a signed receipt for agent accountability. Bots can verify receipt authenticity using the merchant's public key.

The server returns a receipt field in every paid response:

json

{
  "receipt": {
    "id": "rcpt_20260513_a3f9c1",
    "issued_at": "2026-05-13T07:30:00.000Z",
    "endpoint": "/api/v1/kimchi-premium",
    "amount": "0.001",
    "currency": "USDC",
    "network": "eip155:8453",
    "tx_hash": "0x...",
    "payer": "0x...",
    "merchant": "0xcF9223eCe895258dEa8D288AEBcf846Ab8E342fB",
    "signature": "0x...",
    "signer": "0x1AdF0f9e576E94a150208F08D2C31F791932E781"
  }
}

Verification (Python):

python

from eth_account import Account
from eth_account.messages import encode_defunct

payload = "|".join([
    r["id"], r["endpoint"], r["amount"], r["currency"],
    r["network"], r["tx_hash"], r["payer"], r["merchant"], r["issued_at"]
])
recovered = Account.recover_message(
    encode_defunct(text=payload),
    signature=r["signature"]
)
# recovered.lower() == r["signer"].lower() → authentic

Merchant public key is published at: https://api.printmoneylab.com/.well-known/x402 under receipt_signer.public_key

Receipt verification is optional but recommended for agents that need to maintain audit logs or reconcile payments.

Autonomous Invocation Advisory#

This skill is designed to be invoked by the agent when the user asks about Korean crypto markets, Korean financial news, K-pop news, or Korean semiconductor industry news. If your platform supports invocation controls:

• Recommended: Set to "user-invoked only" until comfortable with billing behavior
• Budget: Configure your MCP client's spending limit
• Maximum cost per session: Bounded by your client's spending policy

Security#

• No local code execution — instruction-only skill
