How to Use the FusionSignage MCP in LangChain

Q: How do I use LangChain to update a FusionSignage playlist?

Your LangChain agent can call getplaylist to fetch the current version, modify it based on your logic, and then push the changes using updateplaylist. This can be part of a larger chain that first verifies screen status.

Q: How do I connect my LangChain agent to the FusionSignage MCP server?

Use the MultiServerMCPClient from the langchain-mcp-adapters library, providing the Vinkius endpoint URL. Then, call client.gettools() and pass the resulting list of tools directly to your agent's constructor.

Build automated signage workflows with LangChain. Chain `list_media`, `create_playlist`, and `assign_playlist` to deploy content across your network.

Perplexity

Automate Content Deployment Chains

Link FusionSignage tools together into a powerful sequence. Your LangChain agent can `list_media` to find new assets, use that list to `create_playlist`, and then `assign_playlist` to a specific group of screens you get from `list_groups`. It's a fully automated content pipeline, running without any manual intervention. This isn't just a script; it's a reasoning chain. If `check_fusion_status` fails for a screen during a rollout, the agent can decide to skip it, log an error, and continue the deployment to the remaining screens. You define the logic, and your agent executes the steps.

Dynamic Scheduling with LangChain Agents

Hand off your entire schedule management to an agent using this MCP server. It can `list_schedules` to find open slots, then `create_schedule` to push a new campaign live at a specific time. You just give it the goal, like "run this ad next Monday at 9 AM." Your agent can even react to external data within the same chain. For example, it could check a weather API, and if it's sunny, automatically use `update_playlist` to switch to a summer-themed promotion. This MCP connection ties your agent's logic to your physical displays.

Proactive Network Monitoring

Create a monitoring agent that constantly checks your network's health. It can loop through the output of `list_screens` and run `get_screen_status` on each one, building a real-time dashboard of your entire deployment. When a screen reports an error, the agent takes action. It could try to run `update_screen` with a known-good configuration or send a notification to your team's Slack channel. You're not just getting data; you're building a self-healing system.

Setup guide

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

Common questions about FusionSignage MCP in LangChain

Your LangChain agent can call `get_playlist` to fetch the current version, modify it based on your logic, and then push the changes using `update_playlist`. This can be part of a larger chain that first verifies screen status.

Yes, that's a primary use case. The first step in your chain would be to call `get_screen_status` or `check_fusion_status`. The chain's logic can then decide whether to proceed with `assign_playlist` based on the result.

LangChain lets you build error handling directly into your agent or chain. You can configure it to retry the call, trigger a different tool, or halt the process and send an alert.

Use the `MultiServerMCPClient` from the `langchain-mcp-adapters` library, providing the Vinkius endpoint URL. Then, call `client.get_tools()` and pass the resulting list of tools directly to your agent's constructor.

The server only touches the data required by the tools you call, like your FusionSignage playlist content, media lists, and screen configurations. Your Vinkius endpoint token secures the connection, and all operations happen in an ephemeral, zero-trust environment.
