Google Calendar MCP w/ custom tools

Google Calendar & Custom Tools AI Agent Workflow Overview This workflow implements a sophisticated AI-powered chatbot that acts as a personal assistant. Users can interact with it through a simple chat interface to manage their Google Calendar and execute a variety of custom functions. It uses a modular design using n8n's Multi-Call-Procedure (MCP) to separate different toolsets, making the system scalable and easy to maintain. Technologies & Services Used - n8n: The core automation platform coordinating the entire process. - OpenAI (GPT-4o): The language model that provides the natural language understanding and decision-making capabilities for the AI Agent. - Google Calendar: Used for creating, searching, updating, and deleting calendar events. - External Joke API: A third-party service to fetch random jokes. What It Automates This workflow automates the process of interacting with various digital tools using natural language. Instead of manually navigating the Google Calendar interface or running separate scripts for tasks, a user can simply type a request like: - "What's on my schedule for next week?" - "Create a meeting with John tomorrow at 2pm about the project launch." - "Cancel my 4pm meeting." - "Give me 3 random jokes." The workflow parses this request, understands the user's intent, selects the appropriate tool (e.g., search calendar, create event, call joke API), and executes the action, providing a smooth conversational experience. AI Integration The AI is the central component of this workflow, acting as the brain that connects the user's natural language request to a specific, actionable task. - Natural Language Understanding: The AI Agent node, powered by the OpenAI 4o model, processes the user's chat message to decipher their intent. - Tool Selection & Parameter Extraction: The AI's primary role is to analyze the prompt and decide which of the available tools is best suited to fulfill the request. For example, if the user says, "Adjust my meeting with John tomorrow to 4pm," the AI identifies the UpdateEvent tool.
