Perplexity

Chainable story retrieval

Feed the output of `get_top_stories` directly into a sequence that fetches individual thread details. Your agent evaluates the data and decides the next step without manual intervention. This setup allows you to build pipelines where one tool execution drives the logic for the next. You get full visibility into every step through your standard tracing tools.

Context-aware news filtering

Your agent uses `get_new_stories` to grab raw data and then runs it through your custom logic chains. It discards the noise and keeps only the high-signal posts for your review. Stop wasting time on manual site refreshes. Your agent handles the heavy lifting by pulling the latest content as soon as it hits the wire.

User profile analysis

Trigger `get_user` within your chain to verify the credibility of a poster before acting on their technical advice. It adds a layer of scrutiny to your agent's decision-making process. By integrating this MCP server, your workflows become more reliable. You gain the ability to spot patterns in user activity that usually go unnoticed.

Setup guide

Set up Hacker News Alternative MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

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 Hacker News Alternative 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

    "hacker-news-alternative-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 Hacker News Alternative transactions"
