Trace SEO health in LangChain pipelines

Feed your agent real-time site health scores using `get_website_health` to trigger conditional logic in your chain. Your agent evaluates the current status and decides whether to halt deployment or report a warning. Connect `list_seo_issues` to your workflow to identify specific technical failures. The agent processes the JSON output to decide if an immediate fix is required based on the severity of the findings.

Automate site crawling with MCP Server tools

Trigger a re-crawl when your agent detects a content change by calling `notify_page_update`. This creates a tight feedback loop where the agent updates the crawler as soon as new code hits production. You can also ping the system after a deployment using `notify_sitemap_update`. This ensures the crawler stays synchronized with your latest site structure without human intervention.

Query site portfolios within LangChain

Get a bird's-eye view of your entire infrastructure using `get_portfolio_summary`. Your agent aggregates these metrics to spot patterns across multiple monitored domains. Use `list_websites` to map out your full inventory of monitored properties. The agent keeps track of every active site in your account and routes queries to the correct domain automatically.

Setup guide

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