How to Use the BlogIn MCP in LangChain

Q: How is my BlogIn team directory data protected?

All requests to listteammembers run through an isolated V8 sandbox on Vinkius. Your team directory data is never stored on our servers. The endpoint uses ephemeral execution, meaning your company's internal communications remain private and secure.

Feed internal team updates directly into your LangChain decision chains with this dedicated MCP Server.

Automate company updates inside your LangChain pipelines

The `create_internal_post` tool lets your agent write and publish company updates directly from your run logs. This isn't just a simple API wrapper. Your LangChain agent can read raw engineering notes, summarize the week's commits, and post the final update to BlogIn without you touching a keyboard. By using `list_categories`, your chain determines exactly where the post belongs before publishing. You get clean, categorized internal communication driven entirely by your agent's reasoning steps.

Trace BlogIn data flow using LangSmith

The `get_post_details` tool fetches the exact content of any internal update so your agent can analyze team sentiment. When your chain pulls this data, LangSmith logs the entire payload. You see the exact latency and token cost of each read operation. Combine this with `list_recent_comments` to track how your team reacts to company announcements. The agent evaluates the feedback loop in a single run, mapping out each tool call in your tracing dashboard.

Build smart onboarding flows with the MCP Server

The `list_internal_pages` tool reads your team's wiki pages to feed onboarding context directly to new hires. Your LangChain agent pulls these pages, matches them against the team roster, and identifies missing documentation. Using `list_team_members`, the agent flags who needs to read which page. It connects your internal directory with your documentation library in a single, automated workflow.

Setup guide

Set up BlogIn 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 BlogIn 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({
    "blogin-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 BlogIn transactions"
    })
    print(result["messages"][-1].content)
