How to Use the Netease Yunxin / 网易云信 MCP in LangChain

Q: How do I connect Netease Yunxin / 网易云信 to LangChain?

Install langchain-mcp-adapters and langgraph. You initialize a MultiServerMCPClient pointing to the server URL, then call client.gettools() to pass the functions to your ReAct agent.

Q: Can LangChain agents read Netease Yunxin / 网易云信 chat history?

Yes. The agent calls getsessionhistory to pull transcripts into its working memory. You can pipe this data into other integrations like vector stores or summarization prompts.

Q: Can I send batch messages to thousands of users?

The sendbatchmessage tool accepts arrays of user IDs. Your agent can chunk large lists into smaller payloads, looping through the tool call until the entire batch processes.

Build multi-step LangChain reasoning pipelines to control Netease Yunxin messaging and accounts.

Netease Yunxin MCP Server Account Pipelines

The `create_account` and `update_account` tools let your LangChain agents provision new IM profiles on the fly. You pass the user parameters, and the agent executes the creation step before moving down the chain. If an authentication step fails, your agent can catch the error and fire `refresh_user_token`. You get full visibility into these tool calls through LangSmith, tracking exact latency and token usage for every API hit.

Group Chat State Management

With the `create_team` and `get_team_detail` tools, your ReAct agents can spin up chat groups and verify their configurations. The agent reads the output of the creation tool to grab the new team ID, feeding it directly into the next step. Managing rosters happens in the same execution graph. The agent evaluates business logic and calls `add_team_member` or `kick_team_member` based on the previous chain results.

Chain-Driven Communications

The `send_p2p_message` and `send_batch_message` tools push text or media to users based on LangGraph routing logic. You set the conditions, and the agent decides who receives what payload. To maintain context across long-running pipelines, agents call `get_session_history`. They pull past transcripts, feed them into a prompt template, and generate the next response without breaking the chain.

Setup guide

Set up Netease Yunxin / 网易云信 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 Netease Yunxin / 网易云信 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({
    "netease-yunxin-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 Netease Yunxin / 网易云信 transactions"
    })
    print(result["messages"][-1].content)
