Perplexity

Chainable payment workflows

Feed the output of `list_orders` directly into subsequent reasoning steps. Your agent evaluates current transaction states to decide if `update_order` is necessary without manual intervention. This setup removes the glue code usually required to bridge payment gateways and logic controllers. Each MCP tool call acts as a discrete node in your LangGraph execution flow.

Real-time order synchronization

Trigger `create_checkout` dynamically based on user intent detected earlier in the conversation. The agent handles the session generation, passing the result forward for immediate customer delivery. Observability is native here. Since you are using LangChain, every interaction with this MCP server gets logged through your existing tracing infrastructure for audit.

Automated webhook management

Use `create_webhook` to register endpoints programmatically as your agent spins up new services. This ensures your system stays in sync with payment events as they happen. Your agent can also call `list_webhooks` to verify connectivity before proceeding with high-stakes operations. It keeps your infrastructure state consistent with the Dola Checkout platform.

Setup guide

Set up Dola Checkout MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Dola Checkout tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "dola-checkout-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Dola Checkout transactions"
    })
    print(result["messages"][-1].content)

Common questions about Dola Checkout MCP in LangChain

Install the necessary MCP adapters and initialize the server connection. Pass the tool list into your agent's tool set to grant it access to the full API suite.

Yes. Use the client session method to maintain context across multiple turns. This allows the agent to remember checkout identifiers throughout the conversation.

Absolutely. Because this is a standard MCP server, all tool inputs and outputs are captured by your existing LangSmith setup automatically.

The server returns standard error responses that your agent can interpret. You should implement a fallback chain if a tool call fails during the checkout process.

Your customer details remain within the Dola Checkout environment. The MCP server only relays request arguments and responses; no sensitive payment data is stored locally by your agent.
