Track site changes end-to-end

Want to know what changed across all your domains? Start by calling `list_sites` to pull every Webflow site ID. Then, chain that list through to `get_site_details` for each one, giving you a complete inventory of the platform's status. This sequential process lets an agent build a map of your digital footprint before writing a single line of code.

Automate content population

Need to populate CMS collections across multiple sites? An agent can first use `list_cms_collections` to identify the target structure. Next, it pulls data from an external source and executes `create_collection_item`, making sure every new piece of content lands in the right place. It’s a multi-step process that handles validation—you don't just create; you verify first.

Audit user access and assets

A security audit can be complex. Your agent starts by calling `list_site_users` to get the registered personnel list. It then links this data with `list_site_assets` to check if those users have access rights to specific uploaded files. This combination lets you trace who sees what, which is way more detailed than a simple database query.

Setup guide

Set up Webflow 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 Webflow 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({
    "webflow-alternative-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 Webflow transactions"
    })
    print(result["messages"][-1].content)

Common questions about Webflow MCP in LangChain

Your AI client uses the MCP Server to execute specific actions—like listing all sites or getting order details. The output of one tool call immediately feeds into the next step in your chain, creating a complex decision tree.

Yep. You can run a multi-step process: first, grab all orders using `list_ecommerce_orders`, then check the site details with `get_site_details` to validate payment methods before deciding on next steps.

The MCP Server handles authentication via a single endpoint token, meaning your client never has to deal with multiple credentials. This keeps the connection secure while allowing complex webflow workflows.

The agent architecture helps manage this by building retries or fallback paths into the chain itself. It doesn't just fail; it adapts.

This server touches user identifiers, site URLs (`list_sites`), and e-commerce transaction details found in the order records.
