Build multi-step crypto logic in LangChain

Feed your agents live data using `get_ticker` and `get_vwap` to trigger automated decisions. You define the sequence where one tool result informs the next step in your chain. LangSmith captures every input and output for these calls. You can debug why your agent chose a specific market path when parsing `list_markets` results.

Automate asset tracking within chains

Use `list_assets` to populate a list of tokens and then fire `get_asset` to pull specific metadata for each one. Your agent handles the iteration without manual input. This MCP Server keeps your logic stateless unless you explicitly define a session. You get a clean slate for every chain execution while maintaining full visibility into the agent's decision-making process.

Connect historical data to LangChain workflows

Pull raw performance numbers with `get_ohlcv` and pass them directly into your vector stores or downstream analytical models. The data arrives ready for math operations. Your agents can now compare global weighted averages from `get_gwa` against local exchange data in real time. It removes the friction of manual data ingestion for your custom agents.

Setup guide

Set up Brave New Coin 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 Brave New Coin 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({
    "brave-new-coin-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 Brave New Coin transactions"
    })
    print(result["messages"][-1].content)

Common questions about Brave New Coin MCP in LangChain

Install the necessary MCP adapters and pass the server URL to your agent configuration. Your agent will then pull the tool definitions directly from the server endpoint.

Yes, you can register all eight tools at once. The agent decides which tool to call based on the user prompt and the current state of the chain.

Since you use LangSmith for tracing, you see the exact response time for every tool call. This helps you monitor how fast your agent processes crypto market updates.

No, it's stateless by default. If you need to keep context across multiple prompts, use the client session method provided by the framework.

Your API key stays on your infrastructure and is never exposed to the Vinkius hosting layer. We use ephemeral, zero-trust tunnels to move the cryptocurrency market data from the server to your local agent.
