How to Use the IP Address Parser MCP in LangChain

Q: Can the IP Address Parser in LangChain handle both IPv4 and IPv6?

Yes, the parseipaddress tool checks the version of any incoming IP string and outputs the correct family. Your LangChain agent can use this output to normalize mixed-version log files before storing them.

Parse, validate, and convert IP addresses inside your LangChain reasoning loops without writing regex.

Build IP-aware chains in LangChain

Feed raw network logs into your LangGraph agent and let it parse CIDR blocks on the fly. The `parse_ip_address` tool runs inside your chain to extract range types, family formats, and validation states instantly. It takes the output of your log collector and feeds clean JSON directly into the next LLM step. You don't need to write messy regex or worry about malformed inputs crashing your python process. By registering this MCP Server with your agent, the model inspects the incoming IP, flags the range type, and decides the next routing path based on real network data.

Track network context across multi-step runs

Use LangSmith to trace exactly how your agent handles complex IP structures. When the model invokes `parse_ip_address`, you see the exact input string, the execution latency, and the structured output containing subnet masks and IP versions. This structured feedback loop lets the agent debug its own routing logic. If a tool call returns an invalid IP format, the LangChain agent catches the error, adjusts its prompt, and attempts to clean the input before passing it to the database.

Multi-server log analysis pipelines

Combine this parser with database and API tools in a single LangChain agent. Your model can fetch a suspicious IP from a database, parse its subnet details using this MCP Server, and then write the classification back to your security logs. Because the parser is stateless and fast, it won't bottleneck your multi-agent pipelines. It handles rapid-fire validation calls in parallel, keeping your overall chain execution times well under your strict latency budgets.

Setup guide

Set up IP Address Parser 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 IP Address Parser 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({
    "ip-address-parser-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 IP Address Parser transactions"
    })
    print(result["messages"][-1].content)

Common questions about IP Address Parser MCP in LangChain

Install the LangChain MCP adapter package and initialize the client using your Vinkius HTTP endpoint. Pass the tools retrieved from the server directly into your agent constructor so the model can invoke `parse_ip_address` during its execution loops.

Yes, the `parse_ip_address` tool checks the version of any incoming IP string and outputs the correct family. Your LangChain agent can use this output to normalize mixed-version log files before storing them.

Every tool execution shows up in your LangSmith dashboard with full input and output payloads. This makes it easy to debug why a LangChain agent might have misclassified a specific CIDR block.

The tool returns a clear validation error instead of throwing a system exception. Your agent reads this error message directly from the tool output and can ask the user for clarification or try to fix the format itself.

Your IP addresses, CIDR blocks, and network metadata are processed in isolated, ephemeral V8 sandboxes. Vinkius never logs the payloads or retains the network data sent through the `parse_ip_address` tool, ensuring your internal network layouts stay private.
