How to Use the Groq MCP in LangChain

Q: How do I register the Groq MCP Server in my LangChain project?

Install langchain-mcp-adapters via pip and initialize the client with your Vinkius server URL. You then fetch the tools using gettools() and pass them directly to your LangChain agent constructor.

Q: Can I trace Groq tool calls inside LangChain using LangSmith?

Yes, every execution of tools like createchatcompletion is fully traced. You see the exact token usage and latency metrics in your LangSmith dashboard automatically.

Q: What models can I target with this setup?

You can run listavailablemodels to check the current lineup of high-performance models. The server defaults to Llama 3.3 70B for standard chat tasks.

Run sub-second LPU inference inside LangChain chains to bypass traditional API bottlenecks.

Perplexity

Fast code generation in LangChain chains

This MCP Server exposes `create_chat_completion` to run Llama 3 models on Groq's hardware within your LangChain execution steps. Your agent grabs live text inputs, feeds them to the LPU, and passes the raw output directly to the next chain link. When you call `generate_code` inside a ReAct loop, LangChain handles the state transitions without lag. You avoid the typical multi-second wait times that usually break complex autonomous agent loops.

Track MCP Server latency with LangSmith

You can monitor the execution speeds of tools like `summarize_text` and `explain_code` directly inside your LangSmith dashboard. The dashboard shows the exact milliseconds spent on Groq's LPU versus the network transport overhead. LangChain developers can trace how `list_available_models` resolves dependencies before initiating a heavy text generation task. We give you full visibility into tool arguments and outputs without writing custom debugging wrappers.

Combine LPU speed with local databases

The `extract_entities` tool runs at high speed to pull clean metadata from unstructured inputs inside LangChain. Your pipeline immediately feeds those extracted entities into a SQL database or vector store using standard document transformers. By mixing `fix_grammar` with external API tools in a single LangGraph pipeline, you clean up raw user input before it hits your production systems. This setup prevents bad formatting from ruining downstream automation.

Setup guide

Set up Groq 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 Groq 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({
    "groq-alternative-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 Groq transactions"
    })
    print(result["messages"][-1].content)

Yes, every execution of tools like `create_chat_completion` is fully traced. You see the exact token usage and latency metrics in your LangSmith dashboard automatically.

Your LangChain agent catches any rate-limiting errors returned during heavy inference tasks. You can configure standard LangChain retry logic to handle these transient errors gracefully.

You can run `list_available_models` to check the current lineup of high-performance models. The server defaults to Llama 3.3 70B for standard chat tasks.

Your text and code payloads pass through an ephemeral V8 sandbox before hitting the Groq LPU endpoint. Vinkius handles the authorization token securely, so your API keys are never exposed to the client environment.
