What is the Zip MCP Server?
Connect your Zip (formerly Quadpay) merchant account to any AI agent to automate your Buy Now, Pay Later (BNPL) workflows. This MCP server enables your agent to initiate checkouts, manage order authorizations, and process captures or refunds directly from natural language interfaces.
What you can do
- Checkout Initiation — Create new checkout sessions and retrieve redirect URLs for customers
- Order Management — Authorize and confirm orders across US and Global gateway environments
- Payment Ingestion — Capture authorized funds once goods are shipped to finalize transactions
- Financial Resolution — Process full or partial refunds and void authorized but uncaptured payments
- Status Monitoring — Retrieve real-time status and lifecycle updates for any Zip order
- Account Insight — Access merchant configuration, currency limits, and account-level settings
How it works
- Subscribe to this server
- Enter your Zip Merchant API Key, Region, and Environment (Sandbox/Production)
- Start managing your BNPL payments from Claude, Cursor, or any MCP-compatible client
Who is this for?
- E-commerce Operations — Monitor order lifecycles and process captures/refunds via simple natural language commands
- Financial Controllers — Quickly audit transaction statuses and merchant configurations without opening the portal
- Developers — Integrate BNPL checkout logic and status monitoring into your custom applications

Frequently asked questions
What is the difference between Authorize and Confirm in Zip?
Authorize initiates the transaction and checks for customer funds. Confirm (used in some regions) finalizes the checkout intent before capture.
Can I process partial captures via the agent?
Yes, the capture_zip_payment tool accepts an optional JSON body where you can specify a partial amount to capture if only part of the order is shipping.
How do I handle different regions like US and AU?
Specify your account region ('US' or 'AU') in the configuration settings. The MCP server automatically routes requests to the correct Zip gateway URL.
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 Zip MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
