Build a Semantic Movie Discovery App with Claude Code and Weaviate Agent Skills

Introduction Versatility in agentic coding is increasing as new tools such as Model Context Protocol (MCP) servers and Agent Skills become more common. At the same time, many developers ask the same question when building AI applications: should they use MCP servers or Agent Skills? The important thing is understanding what each approach does well and choosing the one that fits your use case. In this post, we’ll explain what MCP servers and Agent Skills are and how they differ, including architecture diagrams and technical details. In the later sections, we’ll also walk through how to use Weaviate Agent Skills with Claude Code to build a “Semantic Movie Discovery” application with several useful features. Let’s get started! Understanding MCP The Model Context Protocol (MCP) is an open standard introduced by Anthropic that enables Large Language Models (LLMs) to interact with external systems such as data sources, APIs and services. MCP provides a structured way for an AI agent to conne
