How to Use the Webshare MCP in LangChain

Q: How do I check my current webshare quota using LangChain?

Your agent calls getaccountprofile to retrieve your plan limits and bandwidth quotas. This tells you exactly what resources are available before the chain runs into an error.

Q: Does Webshare allow IP whitelisting for LangChain?

Yes, your agent uses authorizenewip to whitelist new IPs for proxy access. This lets specific addresses connect without needing a password for authentication.

Q: Can I list all proxies and their status with Webshare using LangChain?

Absolutely. The agent calls listproxies, which returns all assigned IPs along with their ports, credentials, and current health status so you know what's good to go.

Q: What happens if I need to change my proxy IP using Webshare?

The agent runs requestproxyreplacement. Keep in mind this action is subject to your account quotas, so the tool reports availability first.

Proxy Management with MCP Server

The `get_account_profile` tool lets your agent check the user's plan limits, including bandwidth quotas. It pulls together essential usage metrics that determine if the operation will succeed. You also use tools like `list_authorized_ips` to see exactly which IPs are whitelisted for proxy access without needing a password.

Proxy IP Rotation & Control

Need to change an endpoint? The agent calls `request_proxy_replacement` when the current proxy needs swapping, provided the account quota allows it. If an IP is compromised or no longer needed, your agent runs `revoke_ip_authorization` using a unique ID. It's also smart to call `list_proxies` to get all assigned IPs and their health status before initiating any action.

Tracking Webshare Performance

Before running a big task, the agent runs `get_bandwidth_stats` to pull historical data on bandwidth and requests. This helps prevent unexpected failures. If you need to expand access for a new server or service, your agent executes `authorize_new_ip`, whitelisting the necessary address for proxy usage.

Setup guide

Set up Webshare 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 Webshare 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({
    "webshare-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 Webshare transactions"
    })
    print(result["messages"][-1].content)
