How to Use the Bobascan (Boba L2 Network Block Explorer API) MCP in LangChain

Q: Can I use Bobascan (Boba L2 Network Block Explorer API) to verify contract execution status with LangChain?

Yes. Your agent can call getcontractexecutionstatus inside a ReAct loop to check if a transaction succeeded. This is done dynamically, letting the chain branch based on the execution result.

Q: What is the setup process for running this MCP Server with LangChain?

Install langchain-mcp-adapters via pip and configure the MultiServerMCPClient with the Vinkius endpoint. From there, call gettools() to load all 25 Bobascan tools directly into your agent's toolset.

Run multi-step chain operations on Boba L2 network data directly inside your LangChain pipelines.

Trace and inspect Boba L2 contracts with LangChain

The `get_source_code` tool pulls verified smart contract source code directly into your LangChain agent's reasoning loop. Your agent reads the raw solidity files, extracts variables, and uses `get_abi` to prepare payload structures for subsequent steps without manual copy-pasting. Because LangSmith logs every single step, you see the exact payload passed between these tools in your trace. This keeps your chain runs transparent when debugging complex smart contract interactions on the Boba L2 network.

Track gas fluctuations during active chain runs

The `proxy_gas_price` tool fetches live network gas prices to feed directly into your transaction building chains. Your agent checks `get_ether_balance` for multiple target addresses using `get_ether_balance_multi` before deciding if a transaction should proceed. This setup lets you build automated workflows that pause execution when network fees spike. You get real-time metrics back from the Bobascan MCP Server to guard your deployment budgets.

Audit ERC20 transactions dynamically

The `get_token_tx` tool gets historical transfer logs for any specific ERC20 token contract. Your agent parses these transactions, flags anomalies, and then calls `get_token_balance` to verify current holdings. By chaining these tools, your agent builds a step-by-step historical ledger of any address. LangChain manages the state between these tool calls so your agent never loses its place during deep audits.

Setup guide

Set up Bobascan (Boba L2 Network Block 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 Bobascan (Boba L2 Network Block 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({
    "bobascan-boba-l2-network-block-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 Bobascan (Boba L2 Network Block Explorer API) transactions"
    })
    print(result["messages"][-1].content)

Common questions about Bobascan (Boba L2 Network Block Explorer API) MCP in LangChain

The server returns paginated raw JSON payloads directly to your agent. Your LangChain run parses this data step-by-step, feeding specific transaction hashes into downstream tools like `proxy_get_transaction_receipt` without hitting memory limits.

Yes. Your agent can call `get_contract_execution_status` inside a ReAct loop to check if a transaction succeeded. This is done dynamically, letting the chain branch based on the execution result.

You initialize the MCP Server tools alongside your other toolkits and pass them all to your agent executor. The agent decides when to pull Boba L2 data using `get_abi` and when to push that data to external databases.

Install `langchain-mcp-adapters` via pip and configure the `MultiServerMCPClient` with the Vinkius endpoint. From there, call `get_tools()` to load all 25 Bobascan tools directly into your agent's toolset.

No, this server only queries public Boba L2 blockchain data like transaction histories, contract ABIs, and balances. Your private keys never touch the Vinkius platform, keeping your operational environment secure.
