Cover Image n8n is a powerful workflow automation tool that allows you to connect different services and build sophisticated automation. By integrating Membit with n8n, you can enhance your AI agents with real-time social context, enabling them to provide up-to-date insights about trending topics, news, and conversations happening across the web.

​
Prerequisites

Before you begin, make sure you have:
  • An active n8n instance (cloud or self-hosted)
  • A Membit account with an API key get your API key
  • Basic familiarity with n8n workflows and AI agents

​
Setting Up Membit MCP Client

Follow these steps to integrate Membit with your n8n workflows:
1

Open the Node Panel

In your n8n workflow editor, open the node panel to add a new node to your workflow.

2

Search for MCP Client

In the node search bar, type “MCP client” to find the Model Context Protocol client tool.

The MCP Client Tool should appear in the search results. This tool enables n8n to communicate with external MCP servers like Membit.
3

Configure Membit MCP Client

Add the MCP Client Tool to your workflow and configure it with the following settings:
Endpoint: https://mcp.membit.ai/mcp
Server Transport: HTTP Streamable
Authentication: Header Auth
  - Name: X-Membit-Api-Key
  - Value: <your-api-key>
Tools to Include: All
Replace <your-api-key> with your actual Membit API key.

​
Building Your First Workflow

Now that your Membit MCP client is configured, let’s create a complete workflow that uses real-time context:
1

Add Required Nodes

Create a complete workflow by adding and connecting the following nodes:
  1. Chat Trigger - To receive user input
  2. AI Agent - To process requests and coordinate responses
  3. Google Gemini Chat Model - For natural language processing
  4. Membit MCP Client - For real-time context
2

Connect the Nodes

Connect them in this order:
  • Chat Trigger → AI Agent
  • Google Gemini Chat Model → AI Agent
  • Membit MCP Client → AI Agent

The visual connections show the data flow - the AI Agent receives input from the Chat Trigger, uses the Gemini model for processing, and accesses Membit for real-time context.
3

Test Your Workflow

Use the chat interface to send a test message like:
"Tell me about crypto news"
or
"What's trending in AI today?"
Your AI agent should now respond with current, contextual information pulled from Membit’s real-time data feed.

If successful, you’ll see responses that include recent trends, discussions, and insights that wouldn’t be available in static training data.

Troubleshooting

Problem: Cannot connect to Membit MCP server in n8nSolutions:Verify the endpoint URL is correct: https://mcp.membit.ai/mcpEnsure “Server Transport” is set to “HTTP Streamable”Check that “Authentication” is set to “Header Auth”Verify header name is exactly X-Membit-Api-Key (case-sensitive)Test the connection with a simple request first
Problem: API key authentication is failingSolutions:Confirm the header name is X-Membit-Api-Key (not Authorization)Ensure there are no extra spaces or characters in the API key valueVerify your Membit API key is active and validCheck that the header value contains only the API key (no “Bearer ” prefix)Try regenerating your API key if authentication continues to fail
Problem: AI Agent doesn’t use MCP Client toolsSolutions:Ensure MCP Client is properly connected to the AI Agent nodeVerify “Tools to Include” is set to “All” in MCP Client configurationCheck that the AI model (Google Gemini) supports function callingMake prompts more explicit: “Use available tools to search for current information about…”Test the MCP Client connection independently before connecting to AI Agent
Problem: Nodes won’t connect or show connection issuesSolutions:Verify the connection order: Chat Trigger → AI Agent, MCP Client → AI AgentEnsure all required node inputs are satisfiedCheck that node versions are compatible with each otherTry disconnecting and reconnecting nodes in the correct sequenceRestart the n8n workflow editor if connections appear broken
Problem: Chat interface doesn’t respond or process messagesSolutions:Verify the Chat Trigger node is properly configured and activatedEnsure the workflow is saved and deployedCheck that all nodes in the workflow are properly connectedTest with simple messages first to verify basic functionalityReview workflow execution logs for error messages
