Sequence Decentraland events in LangChain

Feed the output of `get_hot_scenes` directly into your next agent step. You build complex chains that filter live parcel data before deciding which `list_events` call to trigger next. This MCP Server provides the raw data your LangChain agent needs to make logical decisions. You aren't just fetching JSON; you're building automated reasoning pipelines that react to the virtual world in real-time.

Automate marketplace queries with LangChain

Use `get_marketplace_items` to pull specific NFT data into your agent's memory. You can then pipe those results into downstream logic to compare trading histories without manual input. LangSmith tracing lets you watch exactly how your agent handles these API responses. Every tool call gets logged so you can debug the specific logic your chain applied to the virtual world data.

Manage realm access through LangChain

Call `get_realms` to identify optimal entry points for your users. Your agent uses this data to decide which realm configuration best fits the current traffic load. Everything happens inside your existing agent workflow. You just pass the tools from this MCP Server into your agent setup and define the chain logic.

Setup guide

Set up Decentraland (Virtual World Content API) 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 Decentraland (Virtual World Content API) 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({
    "decentraland-virtual-world-content-api-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 Decentraland (Virtual World Content API) transactions"
    })
    print(result["messages"][-1].content)
