What is it?

Dive is a cross-platform desktop application that acts as an MCP host, letting users chat with large language models while those models call external tools exposed through the Model Context Protocol. It works with ChatGPT, Anthropic, Ollama and other OpenAI-compatible models, and supports MCP servers over both stdio and SSE transports.

The app ships with built-in local tools for web fetching, file management and shell command execution, and lets users enable or disable individual MCP tools. It also offers custom system instructions, multiple API keys with model switching, chat draft saving, and chat history search. A managed-server option through OAPHub.ai provides one-click access to hosted MCP servers without local setup.

Dive is available in two builds: a Tauri version and an Electron version. The Tauri build is available on Windows and Linux, while the Electron build covers Windows, macOS and Linux.
