How to Use the Traefik Hub MCP in LangChain

Q: Can LangChain monitor service health using Traefik Hub?

Yes. The traefikgetagenthealth tool allows your agent to test liveness probes across the ingress hubs, making sure the entire chain doesn't fail due to a downed dependency.

Q: Does the MCP Server help LangChain identify available scopes?

Absolutely. You can use traefiklistworkspaces and traefiklistsubscriptions to map out all active logic scopes and understand the boundaries of your application.

Q: How do I check which agents are running in Traefik Hub for LangChain?

Use the traefiklistactiveagents tool. This function locates explicitly hosted Traefik Ingress deployment pods and maps them dynamically onto the hub, giving you a clear operational view.

Verify Agent Status via MCP Server

Before running a multi-step chain, you'll need to know what services are actually up. Use `traefik_get_agent_health` to evaluate liveness probes across your ingress hubs and confirm operational limits. If the status looks good, check which specific pods are mapped out with `traefik_list_active_agents`. This helps your agent decide if a service is available for the next step in the reasoning pipeline.

Monitor API Performance for LangChain

An agent needs to know how fast its steps are. `traefik_get_api_metrics` lets your AI client observe structured execution telemetries, giving you explicit data on error traces and latency. You can also call `traefik_list_apis` to dump the central directory of internal APIs routing across the Gateway. This visibility means your agent doesn't guess; it knows exactly which API exists and how quickly it responds when deciding its next move.

Manage Access Tokens via MCP Server

Your chain might need to access protected resources. Use `traefik_list_subscriptions` to map all external identities currently trying to get logic access over proxy portals. If you see unauthorized activity, call `traefik_revoke_subscription` to ban and completely tear down that consumer token immediately. Conversely, if a new service needs access, the agent can request it using `traefik_approve_subscription`, granting controlled ingress traversal.

Setup guide

Set up Traefik Hub 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 Traefik Hub 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({
    "traefik-hub-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 Traefik Hub transactions"
    })
    print(result["messages"][-1].content)
