"smart" matching MCP servers:

Enables autonomous financial agents to optimize payment recovery by analyzing decline-code retry windows and mitigating involuntary churn, while enforcing balanced double-entry ledger records, HMAC-SHA256 signature verification, and sliding-window fraud detection through an MCP-compatible interface.

Enables autonomous agents to optimize payment recovery by applying decline-code-specific retry windows and reducing involuntary churn through MCP-accessible ledger and fraud-checking workflows.

An MCP server for the SmartBill Cloud API. It lets an MCP client issue and manage Romanian invoices, proformas and payments, download document PDFs, and read VAT rates, series and stock levels.

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.

Enables any MCP client (Claude, Cursor, Windsurf) to commission IMD's agent swarm for websites, sourced reports, code audits, images, smart-contract projects and oracle questions. A built-in saver searches already-shipped work, requires IMD's free pre-check, blocks duplicates, enforces per-order and daily hard caps, and waits for explicit confirmation, so agents can browse and draft for free while paid orders stay bounded and recoverable.

Fully autonomous, crypto-monetized MCP server on the Base network. Provides premium smart contract auditing, patching, and token data arbitrage using the x402 micro-transaction protocol.

Provides order, payment, refund, logistics-ticket, and human-handoff tools for e-commerce customer service, enabling agents to query order data, validate access, and create tickets through FastMCP.

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.
