How to Use the BrioHR MCP in LangChain

Q: Can LangChain handle complex multi-step BrioHR workflows?

Yes, the agent uses ReAct loops to call getemployeedetails and then decide if it needs to query listleaverequests. Each tool execution feeds directly into the next step's context.

Run multi-step HR workflows by connecting the BrioHR MCP Server directly to your LangChain pipelines.

Chain BrioHR tool outputs in LangChain

The `list_employees` tool grabs your core workforce directory so your LangChain agent can feed those IDs straight into other steps. Your pipeline takes the raw list, filters for active staff, and runs downstream logic without manual data exporting. LangSmith tracks every step of this sequence to show you exactly how data moves from one tool to the next. You see the latency of each call and catch failing queries before they mess up your automated HR runs.

Automate payroll and claim validation with MCP Server tools

The `get_payroll_summary` tool fetches monthly financial overviews to run automated checks against your external accounting databases. Your agent compares these numbers to `list_claim_reports` to flag discrepancies instantly. Building this as a ReAct loop allows the agent to decide if it needs to pull more details based on what it finds in the claims. You get a self-correcting audit pipeline that runs on actual API data.

Manage leave and recruiting schedules dynamically

The `get_who_is_away` tool identifies current out-of-office staff to help your agent reschedule internal interviews. It crosses this data with `list_job_candidates` to find open slots that work for your active interviewers. You combine these HR actions with your existing database integrations inside a single LangChain runnable. This keeps your hiring pipeline moving even when key managers are out on vacation.

Setup guide

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