How to Use the CoinGate MCP in LangChain

Q: How do I trigger a CoinGate order in LangChain?

You pass the required order data as a JSON string to the createorder tool. Once the agent receives the schema, it executes the call within your defined chain.

Q: Can LangChain keep my CoinGate data current?

Yes, you call getexchangerates at any point in your workflow. This ensures your LangChain agent always sees the latest market prices before creating a new order.

Chain crypto orders in LangChain

Connect `create_order` to your existing agentic workflows. You define the logic where the output of one step flows directly into the next transaction. Your agents decide when to trigger payments based on user intent. It removes the need for manual intervention in your payment pipelines.

Automate financial data for LangChain

Feed `get_account_info` and `get_exchange_rates` into your LangChain memory. You get real-time financial snapshots during every agent execution. Tracing these calls in LangSmith shows exactly how your agent handles currency fluctuations. You monitor every decision point in the chain.

Manage payouts via LangChain agents

Use `list_payouts` to reconcile your books automatically. Your agent reviews past activity to confirm status without writing custom scripts. This MCP server gives your LangChain agent direct access to your ledger. You stop switching contexts to check your dashboard.

Setup guide

Set up CoinGate 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 CoinGate 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({
    "coingate-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 CoinGate transactions"
    })
    print(result["messages"][-1].content)
