## Verdicts

**Adyen MCP server.** All 38 tools carry read-only, destructive and idempotent annotations, and `--tools` loads a subset under an API credential limited by roles. 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.

**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.

## Before you call either

### Adyen MCP server

1. 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
2. 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
3. Call `refund_payment` with `pspReference`, `currency`, `value`, `merchantAccount` and `reference`. The description's `paymentPspReference` is not the field name
4. 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
5. Give amounts in minor units (1099 for 10.99 EUR). Live use needs `--env=LIVE --livePrefix=` with the prefix from the live Customer Area

### Payman Genie MCP

1. Pass the person's request to `ask_genie` in their own words; don't pick accounts or fill payment fields
2. On `needs_approval`, stop and tell the person; approval happens in their Genie account
3. Retry only after `NOTHING_RAN` or `BUSY`, never after `OUTCOME_UNKNOWN`
4. Treat `done` as acted, not settled; check the activity history before confirming a payment
5. Sign-ins from bridge 0.3.x lack `genie:self`; log out and sign in again to use the self-service tools
