How to Use the Tronscan (TRON Blockchain Explorer API) MCP in LangChain

Q: How do I track resource costs with Tronscan (TRON Blockchain Explorer API) and LangChain?

You use the getacquisitioncoststats tool to gather current resource cost data. Your agent can then sequence this by calling listaccountresources to show exactly what resources were staked or consumed, giving you a full picture of costs.

Q: Can I track token holdings with Tronscan (TRON Blockchain Explorer API) and LangChain?

Absolutely. You can start by getting an account list using listaccounts. Next, run listaccounttokens on that account to see a list of tokens it holds with balances greater than zero. This is the core data for asset tracking.

Q: Does Tronscan (TRON Blockchain Explorer API) support security checks in LangChain?

Yes, there are multiple security tools. Use getaccountsecurity to check account-level safety, and if you're looking at specific transactions, call gettransactionsecurity. The agent can combine these calls for comprehensive risk assessment.

Q: How do I get the top 10 assets using Tronscan (TRON Blockchain Explorer API) and LangChain?

Use the straightforward gettop10 tool. This provides a quick summary of the ten most significant data points or tokens in the network at that moment, perfect for an initial assessment.

Run multi-step blockchain analyses using LangChain.

LangChain: Sequential Account Analysis

You can start by calling `get_account_analysis` to pull initial metrics like Balance, Energy, and Transfers. Then, based on those results, you'll call `list_tokens_overview` to see exactly which assets the account holds. This chain lets your agent decide its next move. For instance, if the analysis shows high transaction volume, it can immediately follow up by calling `get_transaction_detail` for a deeper look into those specific transfers.

Monitoring Smart Contracts with MCP Server

Need to audit a contract? Call `get_contract_analysis` first. This gives you the daily performance stats. You can then follow up by calling `get_contract_top_calls` to see which functions are being hit most often. This sequence helps your agent build a complete profile of the code. It connects high-level contract data with granular call statistics, making it easy for your ReAct agent to report actionable findings.

Tracking Token Movements in LangChain

When tracking funds, start by calling `list_transfers` to get a list of general TRX and TRC10 movements. Then, you can narrow the focus by using `get_stablecoin_blacklist` if those transfers look suspicious. Your agent handles this logic flow automatically. It doesn't just dump data; it builds a narrative showing why certain funds moved or which tokens are flagged based on your multi-step instructions.

Setup guide

Set up Tronscan (TRON Blockchain Explorer 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 Tronscan (TRON Blockchain Explorer 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({
    "tronscan-tron-blockchain-explorer-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 Tronscan (TRON Blockchain Explorer API) transactions"
    })
    print(result["messages"][-1].content)
