The README labels the server alpha, `refund_payment` and the other POST tools send no idempotency key, and failures come back as plain text without an error flag.\n\n**Nevermined API + MCP.** Fees published without a login, 1% on stablecoins, 2% on cards and 2% for the Router. The x402 paywall settles Nevermined plan tokens, so generic x402 clients need its SDK or API to pay.\n\n## Before you call either\n\n### Adyen MCP server\n\n1. Set `ADYEN_API_KEY` in the environment and start with `npx -y @adyen/mcp --env=TEST`. The `--adyenApiKey` flag in the docs page puts the key in the process list\n2. Pass `--tools=` with only the tool names the task needs. The default loads all 38, and the terminal settings schema alone is about 29 KB of source\n3. Call `refund_payment` with `pspReference`, `currency`, `value`, `merchantAccount` and `reference`. The description's `paymentPspReference` is not the field name\n4. Treat a `Failed to ...` reply from a write tool as outcome unknown, not as failure. Do not repeat a refund without checking the Customer Area or the REFUND webhook\n5. Give amounts in minor units (1099 for 10.99 EUR). Live use needs `--env=LIVE --livePrefix=` with the prefix from the live Customer Area\n\n### Nevermined API + MCP\n\n1. Call `quote_service` before `pay_service`; quotes cost nothing\n2. Ask the person to open the `setup_delegation` URL once; you can't mint the first key or budget yourself\n3. Branch on the error `code` and retry only when `retryable` is true\n4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it\n5. Use `sandbox:` keys and mcp.sandbox.nevermined.app until the flow works\n\n## Questions\n\n### Which is better for AI agents, Adyen MCP server or Nevermined API + MCP?\n\nNevermined API + MCP scores 70.8 (BB) on agent readiness against Adyen MCP server's 60.3 (C), and leads in 5 of 7 scored categories. Adyen MCP server leads on transparency \u0026 trust.\n\n### Do Adyen MCP server and Nevermined API + MCP need an API key?\n\nAdyen MCP server needs an API key. Nevermined API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Adyen MCP server and Nevermined API + MCP without installing anything?\n\nAdyen MCP server runs on your own machine, with no hosted endpoint listed. Nevermined API + MCP has a hosted endpoint at https://api.live.nevermined.app.\n\n### Are Adyen MCP server and Nevermined API + MCP open source?\n\nAdyen MCP server is open source (MIT for the server. The Adyen APIs it calls are a closed service under a merchant agreement and the Adyen Terms and Conditions). No open-source release is listed for Nevermined API + MCP.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-nevermined.json, and with the fewest tokens: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-nevermined.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"adyen-mcp-server\", \"b\": \"nevermined\"}`.
