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.

The server itself is hosted; there is nothing to install.

tools/list is free.tools/call without payment returns an x402 v2 challenge: exact amount, network
(eip155:8453), asset (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) and recipient.x_payment, or the X-PAYMENT header over HTTP).Your agent only needs a wallet with a little USDC on Base — no ETH.
