MCPBI serves as a Model Context Protocol (MCP) server, enabling Large Language Model (LLM) clients like Claude and GitHub Copilot to interact directly with locally running PowerBI Desktop instances. By establishing ADOMD.NET connections, it empowers LLMs to understand and analyze tabular models, offering capabilities to execute DAX queries, retrieve model metadata, debug calculations, and optimize performance. This direct communication streamlines Power BI development, allowing developers to leverage AI for enhanced model exploration, DAX assistance, and efficient troubleshooting.
