Perplexity

Chain Bitcoin price data into logic

Connect `get_bitcoin_price_usd` directly into your agent's reasoning loop. You define the sequence where the agent evaluates market conditions before triggering further actions. LangChain treats every tool call as a link in a chain. Your agent takes the output from `get_latest_update_time` to verify data freshness before processing any financial logic.

Automate currency conversion workflows

Feed the output of `list_supported_currencies` into a downstream prompt to handle multi-currency logic. Your chain dynamically selects the right tool based on the user's regional request. This MCP Server provides the raw inputs your agents need. You gain full observability over every step through LangSmith tracing as the agent switches between local currency tools.

Manage stateful financial sessions

Use a persistent session to track price fluctuations over time across your LangChain nodes. Keep your agent grounded by passing context through your defined architecture. Don't rely on static data. The agent calls `get_bitcoin_price_global` whenever the chain requires the most current market snapshot.

Setup guide

Set up CoinDesk Bitcoin Price Index 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 CoinDesk Bitcoin Price Index 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({
    "coindesk-bitcoin-price-index-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 CoinDesk Bitcoin Price Index transactions"
    })
    print(result["messages"][-1].content)
