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**Payman Genie MCP.** OAuth 2.1 with PKCE, two scopes, one-hour access tokens and refresh tokens rotated on every use and revoked on logout. No published pricing, status page, rate limits or changelog.\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### Payman Genie MCP\n\n1. Pass the person's request to `ask_genie` in their own words; don't pick accounts or fill payment fields\n2. On `needs_approval`, stop and tell the person; approval happens in their Genie account\n3. Retry only after `NOTHING_RAN` or `BUSY`, never after `OUTCOME_UNKNOWN`\n4. Treat `done` as acted, not settled; check the activity history before confirming a payment\n5. Sign-ins from bridge 0.3.x lack `genie:self`; log out and sign in again to use the self-service tools\n\n## Questions\n\n### Which is better for AI agents, Adyen MCP server or Payman Genie MCP?\n\nAdyen MCP server scores 60.3 (C) on agent readiness against Payman Genie MCP's 52.5 (D), and leads in 3 of 7 scored categories.
