How to Use the HetrixTools MCP in LangChain

Q: How do I handle HetrixTools rate limits within a LangChain agent loop?

Run getaccountusage at the start of your LangChain run. Your agent can inspect remaining credits and decide whether to proceed with heavy tasks like checkipblacklist or back off.

Q: Can LangChain use HetrixTools to pause alerts during deployments?

Yes, your LangChain agent can call setmaintenancemode to silence notifications before running a deployment script. It uses listuptimemonitors to find the target ID and switches it back to normal when done.

Q: How does LangChain trace HetrixTools MCP Server calls?

Every call to tools like listuptimereports is logged in LangSmith. You can see the exact inputs, outputs, and execution latency of your HetrixTools MCP Server calls in the LangSmith dashboard.

Q: Can I add new targets dynamically?

Yes, use adduptimemonitor within your chain to register new servers on the fly. The agent fetches the contact list using listcontactlists to assign the correct alert recipients.

Get live infrastructure health and blacklist alerts directly inside your LangChain reasoning loops.

Automate Multi-Step Incident Response

This MCP Server exposes tools like `list_uptime_monitors` and `set_maintenance_mode` to let your LangChain agents handle server downtime without human intervention. Your agent can check the list of monitors, detect a failure, and immediately toggle the affected server into maintenance mode. LangChain's ReAct loop passes the output of `list_uptime_reports` directly to the next step in your chain. The agent decides whether to alert your team via a Slack integration or silence notifications using `set_maintenance_mode` based on historical latency trends.

Chain IP Reputation Checks in LangChain

The `check_ip_blacklist` tool lets your LangChain agent run on-demand reputation checks on target mail servers. It passes the resulting IP status to your LangSmith-monitored chains to decide if a server needs immediate quarantine. By combining this MCP Server with other LangChain integrations, you can build self-healing delivery pipelines. If a domain fails `check_domain_blacklist`, your chain automatically triggers a DNS failover step.

Track API Budgets and Monitor Limits

The `get_account_usage` tool provides real-time API consumption metrics to prevent your LangChain chains from hitting rate limits. Your agent checks this usage before initiating large-scale bulk operations across your infrastructure. When running complex multi-step agents, you can query `list_bulk_reports` to verify past runs. This keeps your LangChain memory updated with the exact state of your HetrixTools configuration without wasting API credits on redundant checks.

Setup guide

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