⚓ FreightGate MCP Server

Container shipping intelligence for AI agents — demurrage & detention, local charges, inland haulage, CFS tariffs. Pay-per-request with USDC via x402.

Quick Start

Add FreightGate to Claude Desktop, Cursor, or any MCP-compatible client:

{
  "mcpServers": {

    }
  }
}

That's it. 9 tools auto-discovered. 3 free + 6 paid via x402.

• Tiered pricing — $0.03 to $0.25 per call based on data complexity
• PayAI facilitator — Free, no API key required for payment processing
• 23/23 endpoints verified — Full production health check passed
• 2,547+ records across 14 database tables
• Server card at /.well-known/mcp/server-card.json for auto-discovery

Tools

Paid (USDC via x402)

Free

Payment

FreightGate uses the x402 protocol — the internet's native payment standard for AI agents.

• Currency: USDC (stablecoin, always $1.00)
• Networks: Base Mainnet (EVM) + Solana Mainnet
• Facilitator: PayAI — free, no API key needed
• Settlement: Instant (~200ms)
• No API keys, no accounts, no subscriptions

Your agent sends a request → gets HTTP 402 with payment terms → signs USDC payment → retries with proof → gets data. All handled automatically by x402 client libraries.

Supported x402 Client Libraries

• TypeScript: @x402/fetch or @x402/axios
• Python: x402 package (httpx / requests)
• Go: x402 Go module

Payment Wallets

Data Coverage

API Access

For direct API integration (without MCP):

Example: D&D Calculate

# Free endpoint — no payment needed
curl https://api.shippingrates.org/api/stats

# Paid endpoint — returns HTTP 402 with payment instructions
curl -X POST https://api.shippingrates.org/api/dd/calculate \
  -H "Content-Type: application/json" \
  -d '{"line": "maersk", "country": "IN", "container_type": "40HC", "days": 14}'

Example Response (D&D Calculate)

{
  "line": "maersk",
  "country": "IN",
  "container_type": "40HC",
  "days": 14,
  "free_days": 4,
  "currency": "USD",
  "slabs": [
    { "from": 5, "to": 7, "rate_per_day": 7.5, "days": 3, "cost": 22.5 },
    { "from": 8, "to": 14, "rate_per_day": 15, "days": 7, "cost": 105 }
  ],
  "total_cost": 127.5
}

Example Response (D&D Compare)

{
  "country": "IN",
  "container_type": "40HC",
  "days": 14,
  "comparisons": [
    { "line": "maersk", "total_cost": 127.5, "free_days": 4, "currency": "USD" },
    { "line": "msc", "total_cost": 150.0, "free_days": 3, "currency": "USD" },
    { "line": "cosco", "total_cost": 95.0, "free_days": 7, "currency": "USD" }
  ],
