MCP Agent Demo

A Next.js application demonstrating the integration of large language models (LLMs) with real‑world tools using the Model Context Protocol (MCP) server from Integration.app. This project showcases a fully operational AI assistant capable of dynamically discovering and invoking actions (e.g., creating HubSpot contacts, syncing documents) without hard‑coding every endpoint.

Features

• Dynamic Tool Invocation: The AI agent discovers available tools at runtime via MCP, turning natural language into executable actions.
• Chat Interface: Interactive chat powered by OpenAI GPT-4 (or GPT-4o), with automatic function‑calling support.
• HubSpot Integration: Create and list contacts in HubSpot CRM through preconfigured Integration.app actions.
• Authentication: Customer‑scoped tokens generated on the server; secure Integration.app workspace credentials.
• Scalable Architecture: Designed for production—auditable, tenant‑isolated, rate‑limited, and observable.
