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**Paid.** Paid suits a builder who wants usage metering, credits and invoicing behind one API, with restricted and customer-bound keys, OAuth on the MCP server and a free plan that needs no card. No status page, SLA figure, API changelog or rate-limit numbers were found, both advertised OpenAPI links returned 404, and card payments need the builder's own Stripe account.\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### Paid\n\n1. Call `https://api.agentpaid.io/api/v2` with `Authorization: Bearer \u003ckey\u003e`. A person creates the first key at app.paid.ai. No programmatic signup was found\n2. Give every signal a stable `idempotencyKey` and resend the same key on retry. Signals without one are not deduplicated\n3. Send at most 500 signals a request. A 429 rejects the whole batch, so wait for `Retry-After` and resend it all\n4. Read the `code` field on a 429. `CONCURRENCY_LIMIT_EXCEEDED` carries no `Retry-After` and clears when an analytics query finishes\n5. Install the Python SDK as `paid-python`, the name in its README and `pyproject.toml`. The quickstart's `pip install paid` names a package we could not check\n\n## Questions\n\n### Which is better for AI agents, Adyen MCP server or Paid?\n\nAdyen MCP server scores 60.3 (C) on agent readiness against Paid's 55.1 (C), and leads in 4 of 7 scored categories. Paid leads on agent ergonomics and maintenance \u0026 community.\n\n### Do Adyen MCP server and Paid need an API key?\n\nAdyen MCP server needs an API key. Paid takes an API key or an OAuth sign-in.\n\n### Can an agent call Adyen MCP server and Paid without installing anything?\n\nAdyen MCP server runs on your own machine, with no hosted endpoint listed. Paid has a hosted endpoint at https://api.agentpaid.io/api/v2.\n\n### Are Adyen MCP server and Paid 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 Paid.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-paid.json, and with the fewest tokens: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-paid.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"adyen-mcp-server\", \"b\": \"paid\"}`.
