How to Use the Zenkit MCP in LangChain

Q: Can Zenkit handle deleting data when using LangChain?

Yes, your agent can call deleteentry. This allows you to build cleanup or archival steps into a complex workflow. The action is directly visible within the chain's execution path.

Q: How do I check if Zenkit has available workspaces with LangChain?

You call the listworkspaces tool. This instantly provides a list of all top-level work areas, letting your agent determine where it needs to look next in its reasoning process.

Orchestrate Data Operations in LangChain

The `list_workspaces` tool lets your agent map out all available work areas. You can feed this list into a multi-step chain, allowing the agent to decide which workspace holds the target data before running subsequent steps. Next, use `get_list_details` to check the structure of that specific area. This output guides the next tool call, perhaps deciding if it needs to call `list_elements` or jump straight into listing entries.

Manage Structured Data via LangChain MCP Server

`create_entry` lets your agent populate new records based on a defined schema. Because the output is structured, you can immediately feed this newly created data back into another part of your chain for validation or follow-up processing. If something needs fixing, `update_entry` gives your agent control over existing items. It ensures that the whole process remains self-contained and verifiable across multiple tool calls.

Querying Zenkit Data Structures in LangChain

Need to know what's inside a list? Call `list_entries` to get an inventory of all items. This is perfect for your agent when it needs to decide which data point is relevant without knowing the exact ID beforehand. For deeper checks, use `get_workspace_details`. Your agent can check this first to confirm boundaries before attempting any write operations like calling `delete_entry` or `update_entry`.

Setup guide

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

Common questions about Zenkit MCP in LangChain

Zenkit exposes its tools so your agent can treat them as nodes in a reasoning chain. Your AI client decides if it needs to `get_list_details` before attempting to `create_entry`, making the process highly controllable.

Yes, your agent can call `delete_entry`. This allows you to build cleanup or archival steps into a complex workflow. The action is directly visible within the chain's execution path.

This MCP Server manages structured data, specifically 'entries' and their associated list/workspace metadata. Your agent interacts with this type of organized record information.

Absolutely. Since every tool call is a link in the chain, you get full observability over the data flow. You can track inputs and outputs across multiple calls to `list_workspaces` or `update_entry`.

You call the `list_workspaces` tool. This instantly provides a list of all top-level work areas, letting your agent determine where it needs to look next in its reasoning process.
