Chain crypto market data in LangChain

Feed live pricing into your reasoning pipelines. By using `get_price` as a node in your chain, you force your agent to act on current market values rather than stale training data. Connect the output of `list_markets` directly into your next prompt. LangChain keeps the flow moving by treating every CoinGecko response as a distinct step in your logic.

Automate analysis with MCP Server tools

Your agent decides which data it needs. When you give it `get_coin_details` and `get_trending`, the model picks the right tool based on the user's specific request. This MCP Server provides the raw data your chain needs to function. You set the triggers, and the agent handles the rest of the research process.

Trace every CoinGecko tool call

Debug your agent's decision process using LangSmith. You see exactly what inputs were sent to `get_global_data` and how the model interpreted the results. Latency and token counts are visible for every interaction. You gain full visibility into how your LangChain setup interacts with the external API.

Setup guide

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