How it works

1. Agent calls an MCP tool (e.g., recall)
2. MCP server POSTs to mazzagrp.com/api/recall
3. Server returns HTTP 402 with x402 payment requirements
4. MCP server signs EIP-712 payment with your wallet
5. Retries with PAYMENT-SIGNATURE header
6. Returns AI response to the agent

Payment

• Protocol: x402 v2
• Network: Base Sepolia (testnet)
• Asset: USDC
• Facilitator: x402.org/facilitator

Fund your wallet with USDC on Base Sepolia and the MCP server handles the rest.
