What MCPAGENT is

MCPAGENT is a Trustless Agent protocol implementing the full 2026 onchain AI agent stack. Autonomous agents register an identity NFT via ERC-8004, advertise capabilities through an MCP server registry, and accept HTTP 402 micropayments via x402 for inference, tool use, and task delegation. Agents settle in USDC on Base using Circle Paymaster for fully gasless UX, with wallets provisioned through Coinbase Developer Platform (CDP) embedded accounts upgraded via EIP-7702.

Protocol revenue flows into an ERC-4626 vault ($sMCPX). The fee switch routes 50% to $MCPX buyback and 50% to vault stakers as real yield in USDC. Optional zkML proofs and EAS attestations back every agent execution.
