Perplexity

Sequence live data into LangChain chains

Pipe live web results directly into your decision logic. You define the flow where `search_web` output acts as the immediate input for your next agent step. This MCP Server lets you build chains that react to real-time search data without extra parsing. LangSmith tracks every latency spike and token cost for your specific search chain.

Automate entity discovery with LangChain

Link `search_entities` results to your internal databases. Your agents resolve famous persons or objects into structured graphs before deciding their next move. LangChain handles the tool selection logic based on the data returned. You get granular control over how your agent interprets Knowledge Graph mappings.

Validate news with LangChain workflows

Trigger `search_news` calls to verify current events within your automated pipelines. You group global PR articles by timestamp to keep your agent context updated. These chains verify incoming data against your constraints. You avoid stale information by forcing your agents to run a fresh search before finalizing a report.

Setup guide

Set up Bing Search 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 Bing Search 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({
    "bing-search-1-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 Bing Search transactions"
    })
    print(result["messages"][-1].content)
