How to Use the Zammad MCP in LangChain

Q: How do I search for tickets using Zammad and LangChain?

You use the searchtickets tool. This function takes criteria like dates or keywords, returning a list of matching ticket IDs. From that list, you can then pass the ID to getticket if you need full details on just one specific record.

Q: Can I manage user roles with Zammad and LangChain?

Yep. You can first see all existing roles by calling listroles. Then, your agent can use this information to guide a subsequent action, like creating a new user (createuser) who must be assigned one of those defined roles.

Q: What data does the Zammad MCP Server touch regarding privacy? (LangChain)

This server primarily touches User data. The dataprivacydeleteuser tool handles user deletion via a specific Data Privacy task, ensuring the removal process follows best practices rather than just executing a direct database delete.

Q: What if I need to list all tickets using Zammad and LangChain?

You call listtickets. This returns a paginated list of ticket summaries. If you want details on every single one, you'll need to build a loop that calls getticket for each ID returned by the initial list function.

Multi-Step Ticket Management with LangChain

Need to process a ticket that requires multiple steps? You can chain together calls. For instance, your agent first runs `search_tickets` for a specific ID; then, if the priority is low, it calls `get_shared_draft` to check existing notes before finally invoking `update_ticket`. This multi-step reasoning ensures nothing gets missed. This pattern lets you build robust pipelines. The output from one tool call automatically feeds into the next function in your agent's chain. It's how complex, real-world automation actually works.

Managing Zammad Users with LangChain

Creating or modifying users is straightforward. You can use `create_user` to onboard a new employee, or check their current status using `get_user`. If they've left the company, you don't just delete them; you run the recommended `data_privacy_delete_user` task. LangChain makes sure these sequential HR workflows execute cleanly. The agent handles this logic flow perfectly. It doesn't guess; it follows the required steps: get current data -> validate changes -> execute update/deletion. This gives you full observability over every action taken against your Zammad instance.

Organizational Data Retrieval via LangChain

Retrieving structured data across your company is easy. You can start by listing all available groups with `list_groups`, and then narrow down the scope using `search_organizations`. Once you have an organization ID, calling `get_organization` gives you all the necessary details in a single step. This chained approach lets you build complex decision trees. For example, if your agent needs to check which tags apply to a specific group, it can chain `list_groups`, followed by `get_group`, and then finally `list_tags_for_object`. It keeps the logic transparent.

Setup guide

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