"Kasa Smart" matching MCP servers:

An MCP server that lets your AI coding agent (Claude Code, OpenClaw, Codex, Cursor, etc.) discover and pay on-chain agents registered on ERC-8004, using Coinbase's official x402 protocol. No smart account. No bundler. No relay. Just your EOA, an HTTPS request, and an automatic 402 → sign → retry flow.

Trust infrastructure for the machine economy. Gives AI agents non-custodial smart accounts (ERC-4337), x402 payments, on-chain reputation via ERC-8004 trust registry, and service discovery. 8 tools: create accounts, transfer, check balances, pay for x402 services, publish/discover services, manage payment agreements, and send encrypted messages.

MCP server for Samsung Smart TV in-app payment (Samsung Checkout/DPI) development, enabling AI coding tools to provide real-time API references, code generation, troubleshooting, and implementation guides.

Gives an AI agent a Stellar wallet for x402 payments whose spending budget is installed and enforced on-chain by a Soroban smart contract, so overspending is refused by the contract even if the agent process is compromised, replaced, or restarted. Budgets are declared as scoped, non-rounding data (e.g. 5 USDC per rolling day) that the agent can spend against but cannot alter or redirect.
