mise

mise is a local dev environment CLI that combines tool version management, environment loading, and task running around hierarchical mise.toml config. It fits repos that want the toolchain and common commands declared once, then reused in local shells, CI, and scripted workflows.

• Install and switch project toolchains like Node, Python, Go, Terraform, and other registry-backed tools from shared config files.
• Run one-off commands or full project tasks with the resolved PATH and env using mise exec, mise env, mise run, and mise tasks.
• Inspect active versions, config sources, env vars, and outdated tools before changing a repo or machine setup.

• Many inspection commands expose --json, including config, env, doctor, task, tool, version, installed tool, and outdated views.
• mise exec and mise env let agents use the right toolchain without mutating the parent shell, which is safer than relying on prompt hooks.
• An experimental mise mcp server exists for querying tools, tasks, env, and config, but the CLI plus JSON flags are the more complete automation surface today.

• Automatic directory switching depends on shell activation; unattended workflows should prefer mise exec, mise env, or mise run.
• Commands like mise use, installs, trust prompts, and network-backed version resolution can change local state or require confirmation.
