How can I securely pass card inputs if the chat format is plain text?

The integration routes direct requests to Nuvei's sandbox or live vault using the `create_card_token` feature natively. Since the AI environment is localized and isolated by default, inputs made within Claude or Cursor are ephemeral and pass straight into Nuvei via the secure connection layer without persisting in logs.

Can I query why a specific transaction was declined?

Yes. Ask the agent to use `get_payment` with your transaction ID. The AI will parse the complex payload returned by Nuvei and summarize the error message (e.g., Insufficient Funds, Do Not Honor) directly in human language.

Is it possible to track batch settlements?

Use the `get_transactions` capability. Your prompt can specify that you want to list out the last 20 payments, and the AI will structure them neatly as a tabular view in your chat interface.

About Nuvei MCP Server

Connect your Nuvei merchant account to your AI agent and manage your global payments platform effortlessly.

Pydantic AI validates every Nuvei tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through the Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code — full type safety, structured output guarantees, and dependency injection for testable agents.

What you can do

Payment Processing — Programmatically invoke the create_payment endpoint to handle live orders directly from your chat or workflows.
Transaction Auditing — Query specific payments using get_payment or list multiple transactions with get_transactions to track settlements and statuses.
Card Vaulting & Tokenization — Securely invoke create_card_token without touching raw card data, pushing tokens directly to Nuvei's vault.
Token Retrieval — Look up vaulted payment methods using get_token to analyze returning customers or manage subscriptions.

The Nuvei MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Nuvei MCP Tools for Pydantic AI (10)

These 10 tools become available when you connect Nuvei to Pydantic AI via MCP:

capture_payment

If amount is omitted, captures the full authorized total. Capture a previously authorized card payment

create_card_token

Tokenize plain card details into a vaulted payment token

create_payment

This initiates a real money authorization/charge network request. Returns the Nuvei transaction ID and status. Initialize a new payment intent with Nuvei

delete_token

Stops future recurring charges or 1-click purchases immediately. Delete a vaulted payment token permanently

get_payment

Essential for checking if an async payment cleared. Retrieve the current status mapped to a Nuvei Payment ID

get_token

View details of a previously vaulted Nuvei Card/Payment Token

get_transactions

List or enumerate historical transaction records

refund_payment

Supports partial amounts. Refund a fully captured Nuvei payment

update_token

g. updating an expiry date string) without needing full card details again. Mutate specific fields inside a vaulted token

void_payment

Note: Can only void pending auths. Cancel a pending authorized payment preventing capture

Nuvei + Pydantic AI FAQ

Common questions about integrating Nuvei MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer — your Nuvei MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
