How to Use the Azure Blob Container MCP in LangChain

Q: Can LangChain perform automated cleanup in an Azure Blob Container?

Yes, use the deleteblob tool within your chain logic. The agent will trigger the removal once the defined task conditions are met.

Q: Does LangChain support filtering files in an Azure Blob Container?

Pass a prefix string to the listblobs tool to narrow down your search. This limits the data your agent processes to specific folders.

Q: How does the agent handle file data from an Azure Blob Container?

The agent reads content via getblob and treats it as text input. It then integrates this data into the broader chain of thought.

Use LangChain to chain Azure Blob Container operations directly into your multi-step reasoning pipelines.

Chain storage tasks in LangChain

Feed the output of your agent directly into storage operations. Use `put_blob` to save intermediate results from your chain into your bucket without manual intervention. Your agent decides when to trigger a write based on previous chain steps. This keeps your data flow logical and strictly controlled by the agent's internal reasoning.

Search and inspect with LangChain

Call `list_blobs` to see what files exist in your container. LangChain agents parse these results to decide if they need to fetch more data or move on to the next task. Use `get_blob` to pull file contents into your context window. The agent processes this raw data immediately to inform its next move.

Manage container state via MCP

This MCP server exposes granular file control to your chain. Use `delete_blob` if your agent needs to clean up temporary files after a complex operation finishes. LangSmith tracing lets you see exactly how the agent interacted with your storage. You get full visibility into the inputs and outputs of every tool call.

Setup guide

Set up Azure Blob Container 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 Azure Blob Container 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({
    "azure-blob-container-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 Azure Blob Container transactions"
    })
    print(result["messages"][-1].content)
