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**Orb.** Orb suits a company that bills on usage and wants one API for events, plans, credits and invoices. It publishes an OpenAPI 3.1 file, numeric rate limits, idempotency keys and a dry-run header. Every plan is priced on request and access starts with sales. No scope list for API keys or public sub-processor list was found.\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### Orb\n\n1. Call `https://api.withorb.com/v1` with `Authorization: Bearer \u003ckey\u003e`. A person creates the key in the Orb web app under organisation settings, in test mode or live mode\n2. Send an `Idempotency-Key` of at most 64 characters on every POST and PATCH. A 409 means the first request is still running or the body changed\n3. Add `Dry-Run: True` to check a write first, and confirm `Orb-Dry-Run: true` in the response. Ingest, amend and deprecate event calls ignore it and run for real\n4. Do not send `Idempotency-Key` with `Dry-Run`. Orb returns a validation error\n5. Page with `limit` (default 20, maximum 100) and pass `next_cursor` back as `cursor` while `has_more` is true\n6. Back off exponentially on 429. Test mode allows 5 writes a second and 2,000 ingested events a minute\n\n## Questions\n\n### Which is better for AI agents, Adyen MCP server or Orb?\n\nOrb scores 66.5 (B) on agent readiness against Adyen MCP server's 60.3 (C), and leads in 4 of 7 scored categories. Adyen MCP server leads on security \u0026 auth, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Adyen MCP server and Orb need an API key?\n\nBoth need an API key.\n\n### Can an agent call Adyen MCP server and Orb without installing anything?\n\nAdyen MCP server runs on your own machine, with no hosted endpoint listed. Orb has a hosted endpoint at https://api.withorb.com/v1.\n\n### Are Adyen MCP server and Orb 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 Orb.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-orb.json, and with the fewest tokens: https://www.anchorterminal.com/compare/adyen-mcp-server-vs-orb.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"adyen-mcp-server\", \"b\": \"orb\"}`.
