Chain BoardMix actions into LangChain pipelines

You can now link whiteboard operations directly into your LangChain sequences. Pass the output from `list_files` or `list_templates` into subsequent nodes to automate your drawing and design workflows. This MCP Server allows your agent to decide which whiteboard action to trigger next based on real-time data. It provides the exact inputs required for `create_file` or `list_nodes` to keep your chain moving without manual intervention.

Trace your BoardMix tool calls in LangSmith

Every interaction with your whiteboard is logged through LangSmith. You get full visibility into the latency and data exchange when your agent calls `get_file_versions` or `get_comments`. Debugging becomes straightforward when you see the exact JSON payload sent to BoardMix. You'll know exactly why a specific tool call succeeded or failed within your multi-step agent logic.

Aggregate BoardMix data with external APIs

Combine whiteboard data with databases or other web services inside a single LangChain agent. You can fetch team data using `list_teams` and cross-reference it with information from your CRM or Slack integration. Building these multi-source chains ensures your agent has the full context before modifying a project. It turns BoardMix into an active participant in your broader data processing pipelines.

Setup guide

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

Common questions about BoardMix MCP in LangChain

You use the MultiServerMCPClient to establish a connection via the HTTP transport. Once connected, call the get_tools method to inject the BoardMix functions directly into your agent's execution scope.

Yes, you can define an agent that uses the BoardMix tools to manage whiteboard content. The agent will interpret your prompt and decide whether to list projects or create files based on the task.

Your whiteboard data remains local to your execution environment and is not stored by Vinkius. The MCP Server only touches your whiteboard file metadata and node structures during active sessions.

The adapter handles multiple MCP servers simultaneously. You can include BoardMix alongside your other tools in a single Agent definition.

By default, the connection is stateless. Use the client.session method if you need the agent to remember context across multiple interactions with your boards.
