How to Use the Cerebras Inference MCP in LangChain

Q: Does this MCP server support multiple models in LangChain?

It does. You use listmodels to fetch the available options and swap them dynamically in your agent's configuration.

Chain Cerebras Inference tasks directly into your LangChain pipelines for high-speed, multi-step reasoning agents.

Build reasoning chains with Cerebras Inference

Connect `create_chat_completion` to your existing agentic workflows. You feed the output of a model directly into your next database query or logic gate without manual intervention. This MCP Server provides the raw speed needed for complex chains. You see every token pass through your LangSmith traces, keeping your production pipelines visible.

Manage batch jobs inside LangChain

Trigger `create_batch` to handle massive data processing tasks asynchronously. Your agent tracks status through `list_batches` to decide when the next link in your chain should fire. Automate the lifecycle of your jobs. You don't wait for responses; you build logic that reacts to the state of your inference queue.

Monitor Cerebras Inference operational data

Pull performance metrics using `get_metrics` during your agent execution. You verify the health of your inference requests in real-time. Identify bottlenecks by comparing latency data against your chain execution time. You gain hard numbers on how your agent manages its resources.

Setup guide

Set up Cerebras Inference 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 Cerebras Inference 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({
    "cerebras-inference-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 Cerebras Inference transactions"
    })
    print(result["messages"][-1].content)
