Authentication

Mollie API key api_key discovered Get key ↗

Authorization: Bearer <credential>

In the Mollie Dashboard, open Developers > API keys and create or copy an API key for your account/profile. Use the test key for sandbox requests and the live key for production, as described in Authentication and Testing. Send it as an Authorization: Bearer <api-key> header.

Mollie OAuth access token oauth2 discovered Set up OAuth ↗

Authorization: Bearer <credential>

For Connect/platform integrations, register an app in Developers > OAuth applications, configure its redirect URL, and complete Mollie OAuth to obtain an access token for a connected organization/account as documented in Authentication. Use the resulting bearer token in Authorization: Bearer <access-token>. Some endpoints also require a profileId in the request when using OAuth, as noted in endpoint docs such as Create session.

OAuth 2.0 oauth2 discovered

Authorization: Bearer <credential>

OAuth 2.0 — self-onboarding

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
