Route tickets fast with this MCP Server

The `detect_language` tool feeds direct n-gram analysis into your LangChain agents. LLMs guess wrong on short support queries. This deterministic engine checks the text against 400+ language profiles and spits out an ISO 639-3 code like 'spa' or 'por'. That output becomes the input for your next chain. You build a LangGraph pipeline where the agent reads the code, ignores the LLM's default language bias, and routes the ticket to the correct regional database. It runs locally, so you avoid burning API tokens just to figure out a user speaks Portuguese.

Bypass expensive LLM classification

Calling the `detect_language` MCP tool lets you bypass the cloud entirely. You pass in a short, mixed-language string, and the engine calculates the exact n-gram frequencies. This keeps your ReAct agents moving fast. The tool requires as much text as possible for maximum accuracy, but even on short inputs, it beats an LLM guessing in the dark. Your LangSmith traces will show a massive drop in latency and token usage for the routing step.

Build deterministic routing logic

Using `detect_language` forces your routing system to rely on math instead of probability. Support pipelines break when an agent misidentifies a language and sends a French query to an English RAG setup. You get a hard ISO 639-3 string back. You write a simple switch statement in your LangChain execution path based on that string. It stops the agent from attempting to translate or answer a prompt it fundamentally misunderstood from the start.

Setup guide

Set up Language Detector 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 Language Detector 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({
    "language-detector-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 Language Detector Engine transactions"
    })
    print(result["messages"][-1].content)

Common questions about Language Detector Engine MCP in LangChain

Run `pip install langchain-mcp-adapters langgraph`. Then use `MultiServerMCPClient` pointing to the server URL. Call `client.get_tools()` and pass the resulting tools to your agent.

LLMs hallucinate on short text and charge you for the privilege. This MCP Server uses local n-gram analysis to return a definitive ISO 639-3 code instantly. You save tokens and get better routing accuracy.

Yes. The tool outputs standard codes like 'eng' or 'por'. Your ReAct agent reads that string and triggers the specific downstream chain you built for that language.

The engine calculates n-gram frequencies based on the available characters. If the input lacks enough entropy, the confidence drops. Always feed it as much text as possible to get a reliable read.

No. This MCP Server processes raw customer support queries in memory to calculate n-gram frequencies and drops them immediately. Your tickets are never logged, stored, or sent to an external API.
