Find what is eating your Mac's disk and clear it safely, by hand or through an AI agent.Discky finds the junk that fills a Mac - AI models apps downloaded quietly, build folders coding agents left behind, dead caches — explains each item, and removes it only through the tool that owns it. Free, open source, with an MCP server for Claude Code, Codex and Cursor.

Hi Product Hunt! I'm Alex, and I built Discky because my Mac kept running out of space and I could never tell why.
Two things changed in the last year. Apps started downloading AI models behind my back — a transcription app, an editor's completion feature, a chat client, each parking a few gigabytes somewhere under ~/Library where no Finder window ever shows them. And coding agents build constantly: every project they touch grows a target, a node_modules, a venv, a Docker image, plus the download caches behind them. One day it was "3 GB left" and I had no idea where 250 GB had gone.
Existing disk tools show sizes that don't add up (sparse images at their claimed size, clones counted twice, iCloud files that aren't even on the disk) and they delete with rm. I wanted the opposite:
Honest bytes. Every size is what's actually allocated on disk, clone- and hard-link-aware. "Frees if deleted" is what you really get back.
Explained findings. Each item comes from a rule with a category, a safety label and a plain-language reason.
Official removal only. cargo cache --autoclean, npm cache clean, brew cleanup, brew uninstall --cask, mise uninstall, Ollama's own delete API, docker system prune… Everything else goes to the Trash. There is no fallback to rm.
Agent-ready. discky-mcp exposes the scanner, findings, planner and executor as ten MCP tools, so you can clean up in a chat with Claude Code, Codex or Cursor. Deletion by an agent is off until you turn it on, and the agent always has to show you a plan first.
Local only. No telemetry, no accounts. The only network call is to your own Ollama server.
It's written in Rust with GPUI (the Zed UI framework), it's free and MIT-licensed, and it installs with one command:
Honest caveats: it isn't notarized yet (no paid Apple account behind it), so the cask clears the quarantine flag for you; and it needs Full Disk Access to see all of ~/Library, like any disk tool.
I'd love to hear what Discky finds on your Mac, which rules are missing, and what you'd want an agent to be able to do. The robo-duck says hi. 🦆
