How to Use the ATS Anywhere MCP in LangChain

Q: How do I connect ATS Anywhere to my LangChain agent?

Install langchain-mcp-adapters and use the MultiServerMCPClient to connect to our hosted MCP endpoint. Once initialized, call client.gettools() and pass them directly to your agent executor. This makes all ATS Anywhere tools instantly callable.

Q: Can I trace ATS Anywhere tool calls in LangChain using LangSmith?

Yes, every tool call like listapplicants or getapplicant runs as a standard LangChain tool. This means LangSmith automatically logs latency, input arguments, and raw outputs for every run. You can debug agent decisions in real time.

Q: How does this MCP Server handle multiple company sites?

The server exposes listsites to let your agent query all connected subdomains. Your LangChain agent can use this information to route job creation requests to the correct regional branch automatically.

Run LangChain pipelines that screen applicants and update ATS Anywhere jobs without writing custom API integration code.

Automate screening chains with LangChain

Your LangChain agent can now run candidate evaluations by chaining the `list_applicants` and `get_applicant` tools. The agent starts by running the applicant list to fetch new candidates, then pulls their full profiles. It feeds this data directly into your evaluation chain, saving your team hours of manual sorting. If a candidate looks promising, your agent won't need manual input to grab internal feedback using `get_applicant_notes`. Since this runs as a native LangChain step, you can track the entire decision pipeline in LangSmith to see exactly how your agent evaluates talent.

Sync job openings across your channels

Keep your career pages updated by letting your agent write and publish openings using `create_job`. The agent uses this tool to spin up new listings on ATS Anywhere based on drafts from your shared drives. It then cross-references your current active list with `list_jobs` to prevent duplicate postings. You can chain these tools with database integrations or Slack alerts in your LangChain graph. This means as soon as a job is created, your team gets notified, and your internal databases update instantly.

Audit recruiter activity in real time

Verify team access and monitor recruiter activity using `list_users` and `list_sites` inside your LangChain workflows. This MCP Server lets your agent call the user list to map active recruiters to specific open roles. It then matches them against company sites to ensure correct regional assignment. Before running any critical data updates, the agent calls `get_account_check` to confirm the connection is active and authorized. You get a clean, auditable chain of custody for your hiring data without exposing raw API keys.

Setup guide

Set up ATS Anywhere 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 ATS Anywhere 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({
    "ats-anywhere-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 ATS Anywhere transactions"
    })
    print(result["messages"][-1].content)
