AI product Open source
Tucano is an open-source desktop application for coordinating teams of AI agents on macOS, Windows, and Linux. Agents work in chat-like channels, have roles, tools, memory, and token limits, and can hand work to one another for tasks such as investigation, coding, and review. It uses existing harnesses and sign-ins, including Claude Code, Codex, Cursor CLI, Grok, OpenCode, and Pi, rather than requiring a Tucano API key or per-token billing.
Each agent runs in an isolated harness session with context assembled from its workspace, instructions, memories, skills, and recent conversation. Tucano exposes tools through a local MCP gateway that gives each turn only that agent's permitted tools; sensitive calls become approvals showing the exact action and arguments. It supports MCP connectors, scheduled routines, agent computers in Docker, browser sessions, and optional control of local desktop applications through Vercel Labs' agent-desktop.
The application stores conversations, memory, logins, files, and configuration locally, using the operating system's keychain or keyring for connector credentials. It is distributed for macOS, Linux, and Windows and can also run experimentally without a window on a server. The repository is licensed under Apache-2.0.

Brings AI agents together in a desktop app that feels like a team chat. Each agent gets a role and can hand work to each other, works with tools like Claude Code and Codex, connects via MCP, and lets you approve sensitive actions.
