Andreax — pay-per-call AI tools for agents (MCP + x402)

Remote MCP server: https://pagos.andreax.dev/mcp (Streamable HTTP, JSON-RPC)

Andreax is a remote MCP server with 270 pay-per-call tools for AI agents — text, code, documents, audio, web research and on-chain data. There is no signup and no API key: each call is paid individually with x402 in USDC on Base, from $0.001 per call.

  • No accounts, no keys. The payment is the authentication.
  • Gasless for the payer. EIP-3009 transferWithAuthorization; the settlement gas is paid by Andreax.
  • Free preview. Every tool accepts ?sample=1 and returns an example output at no cost.
  • Discovery in one request. GET https://pagos.andreax.dev/.well-known/x402.json

This repository only contains the public listing (README + directory metadata). The server itself is hosted; there is nothing to install.

Connect

Claude Desktop / Cursor / any MCP client (via mcp-remote)

Clients with native remote-MCP support

Add a remote server with URL https://pagos.andreax.dev/mcp (transport: Streamable HTTP, auth: none).

JavaScript SDK (handles the x402 payment for you)
npm install @andreax-tools/sdk

How payment works

  1. tools/list is free.
  2. tools/call without payment returns an x402 v2 challenge: exact amount, network (eip155:8453), asset (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) and recipient.
  3. Your agent signs an EIP-3009 authorization for that amount and retries with it (argument x_payment, or the X-PAYMENT header over HTTP).
  4. The result comes back together with the on-chain settlement reference.

Your agent only needs a wallet with a little USDC on Base — no ETH.
