ecommerceguide summary

Zen7 Payment Agent is a self-hosted multi-agent payment system from Zen7 Labs for blockchain payments. Its FastMCP server exposes one tool, proceed_payment_and_settlement_detail_info, over SSE on port 8015, so an agent can create orders, sign EIP-712 typed data and execute on-chain transactions. Sub-agents cover payer, payee, settlement, order routing and allowance queries, with PostgreSQL persistence. It is Python 3.13+, run from source under Apache 2.0, and configured for testnet chains.

Why it stands out

Published by Zen7 Labs, it exposes payment and settlement as a single FastMCP tool served over SSE.

How ecommerce teams could use it

ecommerceguide editorial

Illustrative scenarios written by ecommerceguide from the product's documented capabilities. They are not customer case studies.

  1. A team building an AI shopping agent that pays in stablecoins

    The agent needs to create an order and complete payment without a separate checkout page

    Intended outcomeThe MCP tool returns payment and settlement detail information while sub-agents create the order, generate the EIP-712 signature and execute the on-chain transaction.

  2. A developer prototyping agent-to-agent commerce on EVM testnets

    Testing payment flows against Ethereum Sepolia, Base Sepolia or Polygon Amoy before mainnet configuration

    Intended outcomeThe repository's custodial and non-custodial transfer handlers, USDC and DAI permit support and PostgreSQL records cover the order, intent, settlement and audit trail.

  3. A team running a wallet-connected storefront demo

    Connecting MetaMask, Coinbase Wallet or Phantom to an agent-driven payment flow

    Intended outcomeThe allowance agent queries multi-chain token authorisation and the settlement agent confirms details, executes the transaction and monitors its status.

Who it suits

ecommerceguide editorial

Best for

You can self-host Python services and PostgreSQL and want an Apache 2.0 codebase that connects agents to EVM and Solana payments over MCP and A2A.

Probably not for

You need a hosted endpoint, documented authentication, mainnet configuration out of the box or an MCP server that works with a store platform such as Shopify.

Business size
Any stageApache 2.0 source you run yourself, with no pricing or stated audience bounds in the documentation.
