How to Use the Afterpay MCP in AutoGen

Q: How do AutoGen agents collaborate on an Afterpay checkout?

One agent drafts the order details while another calls getafterpayconfig to check the transaction limits. Once they agree the order is valid, they invoke createcheckout to generate the payment token.

Q: Can an AutoGen agent group manage Afterpay refunds?

Yes, your agents verify the order status using getpaymentdetails before deciding to refund. A dedicated refund agent then calls refundpayment to complete the transaction.

Q: How does this Afterpay MCP Server handle schema translation for AutoGen?

The server uses McpToolAdapter to automatically translate payment tool schemas into the format AutoGen expects. This allows your agents to call tools like listpayments without manual schema mapping.

Run multi-agent debates in AutoGen to authorize Afterpay checkouts and verify refund balances before execution.

Resolve Afterpay checkout disputes in AutoGen

The `create_checkout` tool initiates a secure payment session token after your AutoGen agents reach consensus on the transaction. This tool requires a green light from your billing agent, which checks order details before the checkout token is generated. Your agents debate the validity of the purchase based on risk rules. Once they agree, the system invokes the tool to start the customer's payment session.

Verify transaction limits via this MCP Server

The `get_afterpay_config` tool retrieves the active minimum and maximum limits of your merchant account for your agents to review. This tool feeds account rules directly into the conversation, letting your compliance agent debate your sales agent on order sizes. If a cart exceeds the maximum limit, the compliance agent blocks the checkout. This prevents API errors by stopping bad requests before they leave the AutoGen environment.

Debating refunds using live transaction details

The `get_payment_details` tool pulls full settlement logs and order states so your support agents can audit refund requests using this MCP interface. This tool provides the raw financial data that your refund agent uses to verify the remaining balance before executing a payout. Once the refund agent confirms the balance, it calls `refund_payment` to credit the buyer. The entire debate and execution process happens autonomously within your agent group.

Setup guide

Set up Afterpay MCP in AutoGen

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] package
Active Vinkius subscription with a valid endpoint token

1

Install AutoGen with MCP
Run pip install "autogen-ext[mcp]" autogen-agentchat. The MCP extension includes mcp_server_tools for stateless tool access.
2

Fetch tools from the MCP
Call mcp_server_tools(SseServerParams(url=...)) with your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Run your agent
Pass the tools to AssistantAgent and call agent.run(). The agent invokes Afterpay tools and returns structured results.

agent.py

from autogen_ext.tools.mcp import SseServerParams, mcp_server_tools
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

tools = await mcp_server_tools(server_params)

agent = AssistantAgent(
    name="Afterpay_assistant",
    model_client=OpenAIChatCompletionClient(model="gpt-4o"),
    tools=tools,
)

result = await agent.run("List recent Afterpay data")
print(result.messages[-1].content)

Prerequisites

Python 3.10+ installed
autogen-ext[mcp] + autogen-agentchat
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Same packages as above. McpWorkbench is ideal when your agent needs stateful sessions across multiple tool calls.
2

Use McpWorkbench as context manager
Wrap your agent in async with McpWorkbench(...) to maintain shared state and resources. The workbench manages the full MCP session lifecycle.
3

Run with workbench
Pass workbench=workbench to your agent. State is preserved across multiple tool calls within the same session.

agent.py

from autogen_ext.tools.mcp import McpWorkbench, SseServerParams
from autogen_agentchat.agents import AssistantAgent
from autogen_ext.models.openai import OpenAIChatCompletionClient

server_params = SseServerParams(
    url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)

async with McpWorkbench(server_params) as workbench:
    agent = AssistantAgent(
        name="Afterpay_assistant",
        model_client=OpenAIChatCompletionClient(model="gpt-4o"),
        workbench=workbench,
    )

    result = await agent.run("List recent Afterpay data")
    print(result.messages[-1].content)
