Automate SEO research with LangChain

Feed `get_domain_overview` results directly into your LangChain agent chains. The agent reads the metrics and decides whether to pivot the strategy or continue the investigation. Stop manually copying data between tabs. Your agent pulls raw SEO stats and feeds them into the next step of your logic flow automatically.

Analyze backlinks within your LangChain pipeline

Use `list_broken_backlinks` to trigger automated cleanup tasks. The agent identifies the dead links and passes them to your site management tools for immediate action. This MCP Server provides the raw data your agents need to fix site architecture issues. It removes the need for manual monitoring of link health.

Build keyword-driven content loops

Connect `list_keyword_ideas` to your generation agents. Your code parses the output to create content briefs based on live search volume data. Use this data to feed your internal databases or vector stores. The agent works through the list to build a comprehensive map of search intent.

Setup guide

Set up Ahrefs 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 Ahrefs 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({
    "ahrefs-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 Ahrefs transactions"
    })
    print(result["messages"][-1].content)
