The Universal Appointment Agent is a next-generation, AI-driven booking solution built for the Internet of Agents Hackathon @ Solana Skyline. Unlike traditional scripted systems, it uses Mistral AI for natural language conversations, dynamically adapting to multiple business types while directly integrating with Google Calendar for scheduling and Google Sheets for customer data management. The agent supports web-based APIs, voice calls via Twilio, and is fully compliant with the MCP/Coral Protocol, enabling discoverability and integration into broader ecosystems. Key features include multi-business configurations, real-time availability checks, smart scheduling to avoid conflicts, and timezone awareness for global use. Its modular architecture allows easy extension, while robust security ensures safe handling of API keys, OAuth tokens, and user inputs. With the ability to handle 100+ concurrent users and deliver responses in under 2 seconds, the agent is production-ready and scalable. By reducing the need for human receptionists, providing 24/7 availability, and delivering customer interaction insights, the Universal Appointment Agent offers both business value and technical innovation. It has been designed with developers in mind, featuring clear documentation, comprehensive testing, and simple integration points. Whether through a website chat, a phone call, or integration into Coral Protocol’s registry, this system demonstrates the future of AI-powered business automation.
