How to Use the LinkedIn Page Management MCP in LangChain

Q: Can LangChain automate comment replies using this LinkedIn Page Management MCP Server?

Yes, you can build a chain that combines listpostcomments and createpostcomment. The agent reads the incoming text, evaluates it, and posts the response.

Q: Can I manage multiple company pages at the same time?

Yes, you use listmanagedpages to get the list of active organization IDs. From there, your agent routes posts and comments to specific pages using their respective URNs.

Build multi-step publishing and moderation chains using LangChain agents connected to your LinkedIn company pages.

Moderate comments with LangChain chains

The `list_post_comments` tool pulls recent feedback from your company posts directly into your LangChain agent's execution loop. Your agent checks the text against your brand guidelines and uses `create_post_comment` to reply instantly when appropriate. This setup runs entirely within a single chain, letting you pass output from one step directly to the next. You get full visibility over the comment processing pipeline via LangSmith tracing.

Multi-step publishing using this MCP Server

The `create_page_post` tool publishes fresh updates to your corporate feed based on upstream data sources in your chain. Your agent queries your internal databases, structures the copy, and posts it without manual copying and pasting. If a post misses the mark or requires immediate removal, the agent invokes `delete_page_post` to clean up the page. You control the logic while the agent handles the API calls.

Discover company IDs dynamically

The `list_managed_pages` tool identifies every page your account can access to pull the correct organization URNs. Your LangChain agent uses these IDs to route subsequent posts to the right target page. Combining this tool with `list_page_posts` lets your agent audit your entire network of company pages in a single run. You no longer have to hardcode organization IDs into your application files.

Setup guide

Set up LinkedIn Page Management 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 LinkedIn Page Management 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({
    "linkedin-page-management-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 LinkedIn Page Management transactions"
    })
    print(result["messages"][-1].content)
