Perplexity

Chain procurement data with LangChain

Feed `get_spend_analysis` results directly into your next reasoning step. You can link tool outputs to build complex logic without manual data handling. Your agent decides if it needs `list_risks` or `list_suppliers` based on the previous link in the chain. This creates a tight feedback loop for your procurement pipelines.

Automate contract pipelines

Trigger `list_contracts` to fetch active agreements for your workflow. The MCP Server ensures your agent works with live data every time it runs. Pass these details to `get_contract` to drill down into specifics. Your LangChain agent handles the state transitions between these calls automatically.

Monitor approval workflows

Use `list_approvals` to check for pending tasks that require human attention. Your agent captures these items as part of an autonomous sequence. It flags roadblocks before they stall your project timelines. The integration keeps your procurement process moving using direct API interactions.

Setup guide

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