How to Use the Vestiaire Collective MCP in LangChain

You can first list your current inventory using listmysellingitems. Then, you can feed those item details into the agent, which will use that data to cross-reference market value trends via analyzepricetrends.

Q: Can I search multiple times with Vestiaire Collective and LangChain?

Absolutely. Since your client supports persistent context (client.session()), you can run a complex query—like searching by brand, then analyzing its price trends—and keep that information available for subsequent, related questions.

Perplexity

Multi-Step Luxury Search

Start with a broad search, then narrow it down. You can use `search_luxury_items` to find general keywords like 'Chanel tweed,' and then immediately pipe that list of results into `get_item_details`. This chain lets you quickly pull specific data points—like the item's condition, material, or if it matches a certain size—on every single result found. This is perfect for building complex research agents. The agent won't just call one tool; it’ll decide to first run `list_catalog_categories`, then use that output in conjunction with `search_by_brand` to give you a highly filtered list of available goods.

Price Trend Analysis

Want to know if an item's current price is accurate? Your agent can run `list_available_brands` first, and then pass the selected brand name into `analyze_price_trends`. This shows you how a specific luxury category has valued up or down recently. The chain also lets you verify inventory. You can call `list_my_selling_items` to see what's currently listed in your closet, and then use that list of item IDs as context when researching market value using the price trends tool.

Catalog Mapping

This server gives you a complete picture of the marketplace. You can start by calling `list_catalog_categories` to see if shoes, bags, or accessories are available. Next, run `list_available_designers` to narrow the focus down to specific creators. Then, your agent combines those results: it takes a designer's name and feeds it into the advanced filtering tools—specifically `search_with_advanced_filters`—to pull only items matching that profile. It’s all one continuous reasoning path.

Setup guide

Set up Vestiaire Collective 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 Vestiaire Collective 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({
    "vestiaire-collective-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 Vestiaire Collective transactions"
    })
    print(result["messages"][-1].content)

Common questions about Vestiaire Collective MCP in LangChain

You treat the entire MCP Server as a tool set for your agent. Instead of writing specific API calls, you define the goal (e.g., 'find me a vintage Dior bag') and let your agent decide which tools—like `search_with_advanced_filters` or `get_item_details`—to run and in what order.

You can first list your current inventory using `list_my_selling_items`. Then, you can feed those item details into the agent, which will use that data to cross-reference market value trends via `analyze_price_trends`.

Absolutely. Since your client supports persistent context (`client.session()`), you can run a complex query—like searching by brand, then analyzing its price trends—and keep that information available for subsequent, related questions.

Yes, the server handles three main ways to search: keyword matching (`search_luxury_items`), brand/category filtering (`search_by_brand`), and deep filtration using multiple parameters like color or material (`search_with_advanced_filters`).

This server touches publicly available item metadata, including brand names, materials, sizes, and listing prices. It does not handle user authentication credentials.
