MCP-Server

This repository contains workflow configurations for a Model Context Protocol (MCP) server that integrates AI capabilities with n8n automation platform.

Overview

The project consists of two main components:

1. MCP Server - A server that exposes AI tools through n8n's MCP Trigger and connects various services.
2. Social Media Post Generator - A workflow that uses AI to create professional social media content.

Features

• AI-powered social media post generation
• Todo list management via Airtable
• Calculator functionality
• Extensible architecture for adding more AI tools

Workflows

MCP Server

The MCP Server workflow acts as the central hub for all AI functionality. It:

• Exposes a webhook endpoint at /test
• Provides access to the following tools:
  • Calculator
  • Social Media Post Generator
  • Airtable Todo List Management (List, Add, Update)

Social Media Post Generator

This workflow is designed to:

• Accept a query input
• Use OpenAI's GPT-4o-mini model to generate professional social media content
• Return the generated content to the calling workflow

Requirements

• n8n version 1.0.0 or higher
• OpenAI API account
• Airtable account with appropriate permissions

Setup Instructions

1. Import Workflows

   • Import MCP_Server.json and Social_Media_Post_Generator.json into your n8n instance

2. Configure Credentials

   • Set up OpenAI API credentials for the Chat Model node
   • Configure Airtable Personal Access Token for the Airtable Tool nodes

3. Airtable Setup

   • Ensure you have a base with ID appEVZyRnoMDAkayU (or update the configuration to match your base)
   • Create a table named "Table 1" with columns:
     • Name (string)
     • Completed (boolean)

4. Activate the Workflows

   • Activate both workflows in your n8n instance

Usage

Using the MCP Server

The MCP Server exposes various AI capabilities through the n8n interface. You can interact with it by:

1. Creating Social Media Posts

   Use the create_social_media_content tool with a query parameter
   

2. Managing Todo Items

   - List all todos using the List_ToDos tool
   - Add a new todo with the Add_ToDo tool (provide Name and Completed status)
   - Update an existing todo with the Update_ToDo tool (provide record ID, Name, and Completed status)
   

3. Performing Calculations

   Use the calculator tool for mathematical operations
   

Technical Details

Workflow Connections

• The MCP Server Trigger connects to all available tools
• The Social Media Post Generator is triggered by the Social Post Generator tool
• All Airtable operations are configured as separate tools

Configuration Notes

• The Social Media Post Generator uses the GPT-4o-mini model
• Airtable interactions are configured for a specific base and table
