RailRouter Lite

Intelligent real-time payment rail router for AI agents.

Live MCP Endpoint
https://railrouter-lite.sgdata.workers.dev/mcp

Tool: route_payment

Routes a payment request to the optimal rail (Stripe MPP, x402, or Google AP2) in real time based on cost, latency, and success rate.

Input Schema

{
  "amount_sgd": { "type": "number", "description": "Amount in SGD" },
  "target_server_url": { "type": "string", "description": "The MCP server that needs payment" },
  "tool_name": { "type": "string", "description": "Name of the tool being paid for" },
  "preferred_rail": { "type": "string", "enum": ["mpp", "x402", "ap2", "auto"] }
}
Response Example
JSON{
  "success": true,
  "chosen_rail": "mpp",
  "payment_intent": "rr_1744641123456",
  "estimated_fee_sgd": 0.13,
  "message": "Routed via MPP in 12ms"
}
Every routing decision is automatically logged to D1, creating compounding intelligence (cost, latency, success rate per category). No other MCP server offers intelligent cross-rail routing.
Compatible with LangChain, LangGraph, CrewAI, AutoGen and any MCP client.

    A neutral, non-custodial payment router for AI agents: it discovers which payment rails a paid endpoint accepts (x402 on Base/EVM, Solana, MPP), then pays across them using the caller's own wallet key. Three tools — discover_payment_rails, pay_for_resource, payment_history.
