Deterministic data scaling for LangChain

The `scale_features` tool forces your numeric data into a consistent range before it hits your model. You stop worrying about feature variance causing gradient explosions during training. Your agent selects the scaling method as part of a multi-step chain. It processes the raw data, applies the math, and passes the cleaned output to the next node.

Chainable normalization logic

Integration with LangChain means your normalization steps are fully observable. You track every input and output through your standard tracing tools. Each call to `scale_features` acts as a discrete link in your agent's reasoning process. You define the flow, and the server handles the heavy lifting locally.

Local execution for private data

Data never leaves your environment when you use the Feature Scaler Engine. The server operates entirely within your local sandbox, keeping your sensitive training sets secure. Your LangChain agent invokes the tool directly, ensuring the normalization happens on your machine. No external dependencies touch your private data.

Setup guide

Set up Feature Scaler Engine 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 Feature Scaler Engine 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({
    "feature-scaler-engine-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 Feature Scaler Engine transactions"
    })
    print(result["messages"][-1].content)

Common questions about Feature Scaler Engine MCP in LangChain

Use the langchain-mcp-adapters package to bridge the connection. Pass the tool list returned by the client into your agent's configuration.

Yes. The server supports stateless operations that fit right into your streaming pipelines. Just ensure your agent calls the tool before passing data to the model.

It processes data in-memory locally. If your dataset is huge, slice it into chunks before sending it through the tool to keep performance high.

The tool ignores non-numeric columns and focuses on the features you specify. You'll need to clean your text or categorical data before running the scaler.

Your data remains local to your execution environment. The Feature Scaler Engine only performs mathematical transformations on the numbers you provide, with no telemetry sent to external servers.
