Langflow is an open-source visual tool for building agentic applications using reusable UI components and Python code. The tutorial demonstrates creating an agent that uses watsonx.ai LLM to search news and generate charts by integrating MCP (Model Context Protocol) tools. It shows how to set up custom components, connect MCP servers for chart generation, and deploy Langflow applications as MCP servers for integration with other agentic systems.
