QodeAssist integrates large language models directly into the Qt Creator IDE to assist with C++ and QML development. It connects to both cloud providers (Claude, OpenAI, Google AI, Mistral, DeepSeek) and local runtimes (Ollama, llama.cpp, LM Studio), offering smart autocomplete and conversational assistance. The plugin supports MCP for tool calling and can operate as an MCP server or client, enabling other tools to leverage its project context or external tools.
