The Qt4 Documentation server is an offline-only Micro-Agent Communication Protocol (MCP) server specifically designed to provide comprehensive access to Qt 4.8.4 documentation. It processes local HTML documentation, intelligently extracts and converts content into standardized Markdown format, and offers fast full-text search capabilities using SQLite FTS5. This tool enables seamless integration for AI agents, large language models (LLMs), and integrated development environments (IDEs) to query and consume Qt 4.8.4 reference material efficiently without requiring an internet connection.
