Sparewise MCP server

Sparewise

See why your Windows drive is full, and free space safely.

Sparewise finds the space that developer and AI tools quietly fill: package caches, local AI models, Docker and WSL disks, browser and editor caches, plus ordinary Windows clutter. It tells you what each item is and whether it comes back by itself. It frees space only when you say so, and anything it moves can be put back.

Why Sparewise

• What it removes can be put back. It goes to the Recycle Bin or an undo window, and comes back with one click.
• Knows what rebuilds itself. Only caches that come back on their own are offered, each with a tested rule, not a guess.
• Built for developers and AI users. Model folders, Docker and WSL disks, and AI coding tools' caches, measured one by one.
• Explains a slow PC honestly. A nearly full drive, memory that is really short, a program growing for days, a restart waiting. No "RAM booster" tricks.
• Works with your AI assistant. Claude, Codex and other MCP clients can plan and free space, only within limits you set, with every change recorded and undoable.
• No telemetry, no account. Nothing leaves your PC.

Quick start

The direct download may make Windows warn the first time ("Windows protected your PC") because the installer is not code-signed yet (the Microsoft Store version is signed by Microsoft). Choose More info → Run anyway. Each release lists SHA-256 checksums, so you can check that a download is the genuine one.

What it finds

• Developer caches: npm, pnpm, Yarn, pip, uv, conda, Cargo, Go, Gradle, Maven, NuGet and more
• AI: Ollama, LM Studio and Hugging Face models one by one, with when each was last loaded; caches of Cursor, Claude, Copilot, Codex and other AI coding tools
• Containers and virtual disks: Docker and WSL disks that never shrink by themselves
• Windows: temporary files, update leftovers, old installers in Downloads, browser caches, the Recycle Bin, hibernation file
• Your own files: large videos, duplicates and folders you have not opened in months. Reported only: Sparewise never removes these by itself.
