Orchestrate Hiring Workflows via LangChain

You can start by calling `list_active_job_postings` to see what roles are open right now. Then, your agent figures out the next step—maybe it needs to get deeper details using `get_job_details` for a specific opening. From there, the chain continues: pull all relevant candidates with `list_candidates`, and if you find one who needs attention, update their status immediately by calling `update_candidate_hiring_stage`. It's pure multi-step logic.

Manage User Data in LangChain

Need to know who’s running the show? The agent pulls the authenticated user profile using `get_current_user`. If you need to check if a connection is even live before proceeding, just run `check_api_health`. This foundational data keeps your entire workflow stable. This setup lets you build chains that react to real-time system status and user context. It's about reliable connections first.

Candidate Lifecycle in LangChain

Building a full candidate journey is easy with the MCP Server. You can manually input a new person using `create_new_candidate`, or you might just want to see who’s already in the system via `list_candidates`. The best part? You track them through stages by calling `update_candidate_hiring_stage`. It lets your agent handle everything from initial entry to final stage movement, all within one reasoned chain.

Setup guide

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