Chainable research pipelines for LangChain

Feed output from `faceted_search` directly into subsequent logic gates. Your agent evaluates the metadata returned to decide if it needs to trigger `search_by_creator` or pivot to `search_fulltext` based on the initial hit count. This creates a non-linear flow where the agent navigates the archive based on real-time feedback. Stop guessing the path and let the chain adapt to the data it finds.

Dynamic tool selection within LangChain agents

Your LangChain agent chooses the right tool for the job. It might call `search_by_subject` to define the scope of a topic before using `search_by_date_range` to narrow down the timeline. Each tool call is tracked through your existing LangSmith infrastructure. You get full visibility into how your agent interacts with the archive index without extra configuration.

Multi-server aggregation

Combine this MCP server with other data sources in a single LangChain execution environment. The agent treats the Internet Archive as just one node in a larger graph of information. Query across disparate databases and the archive simultaneously. The agent merges these streams into a coherent answer for your end users.

Setup guide

Set up Internet Archive 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 Internet Archive 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({
    "internet-archive-search-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 Internet Archive Search transactions"
    })
    print(result["messages"][-1].content)
