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
