Kasetto is an open-source CLI agent harness and configuration orchestrator created by pivoshenko. It is designed to manage, configure, and synchronize AI coding agent environments and Model Context Protocol (MCP) servers across developer workspaces. Operating directly in the terminal, Kasetto coordinates agent tooling and dependencies using declarative configuration defined in `kasetto.yaml`. It provides interactive startup flows to initialize agent environments, manage tool access, and coordinate integrations across supported agents (such as Pi) and MCP-compatible backends. Kasetto differentiates itself from standalone coding agents by acting as an orchestration layer rather than a single hardcoded assistant. It focuses on cold-sync performance, deterministic environment setup, and unified MCP server lifecycle management across multiple coding tools. Kasetto is distributed as open-source software via GitHub and Homebrew formula repositories.
