Langflow is a visual framework for building multi-agent and RAG applications using a drag-and-drop interface. By integrating Membit with Langflow, you can enhance your AI agents with real-time social context, enabling them to access current trends, breaking news, and live conversations from across the web through a node-based visual workflow.

​
Prerequisites

Before you begin, make sure you have:
  • Langflow application installed (download here)
  • A Membit account with an API key get your API key
  • Basic familiarity with Langflow’s visual workflow builder
  • A Google AI Studio API key for the chat model (optional)

​
Setting Up Membit MCP Tools

Follow these steps to integrate Membit with your Langflow workflows:
1

Create New Flow

Open the Langflow application and click Add New Flow to start building a new workflow.

STDIO Configuration:
  • Name: membit-mcp
  • Command: npx -y mcp-remote https://mcp.membit.ai/mcp
  • Argument 1: --header
  • Argument 2: X-Membit-Api-Key:${MEMBIT_API_KEY}
  • Environment Variables: MEMBIT_API_KEY <your-api-key>
Replace <your-api-key> with your actual Membit API key. Keep this credential secure and don’t share it with unauthorized users.
  1. Click Add Server to save the configuration
  2. Click Toggle Tool Mode to enable the MCP tools

Building Your First Workflow

Now let’s create a complete workflow that uses Membit’s real-time context:
1

Add Agent Component

Search for “agent” in the component library and click Add to add an Agent component to your workflow.

The Agent component acts as the orchestrator, managing how your workflow processes requests and coordinates responses.
2

Configure Agent Model

Configure the Agent component with your preferred language model:
Config agent component
  • Model Provider: Select “Gemini 2.5 Flash” (or your preferred model)
  • API Key: Set your Google AI Studio API key
You can use other model providers like OpenAI, Anthropic, or local models depending on your preference and requirements.
3

Connect MCP Tools

Connect the Membit MCP component to the Agent Tools input to provide real-time context capabilities.
This connection enables your agent to access Membit’s real-time social media context when processing user queries.
4

Add Chat Components

Add Chat Input and Chat Output components to create an interactive interface:
  1. Chat Input - To receive user messages
  2. Chat Output - To display agent responses

Try asking questions like:
  • “Tell me about crypto trends”
  • “What’s happening in AI today?”
  • “Give me the latest tech news”
