Enable and drive the LinuxToys MCP server to manage Linux apps on the user's machine like a user would - search the catalog, read app pages (descriptions, screenshots, donation links), install and remove apps, install local package files (.deb, .rpm, .appimage and more, optionally downloaded from a URL), install and remove Flathub app extensions/addons, check for and apply LinuxToys app updates, change LinuxToys settings, and translate descriptions. Use when the user asks to install or remove…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LinuxToys MCP LinuxToys is a cross-distribution Linux app manager. This skill lets you use it on the user's behalf, exactly like a user would: browse the catalog, open app pages, install/remove apps, and change app settings. Password prompts always appear on the **user's screen** — never ask the user to hand you their password. ## 1. Check whether the server is running The server is an opt-in systemd **user** service (`linuxtoys-mcp.service`) that ships with the app but is not enabled by default. Check it without any credentials: ```bash curl -fsS http://127.0.0.1:7420/health ``` - A JSON response means the server is up → go to section 3. - Connection refused means it is not enabled → section 2. ## 2. Enable it (no root required) First check whether the unit exists: ```bash systemctl --user cat linuxtoys-mcp.service >/dev/null 2>&1 && echo unit-installed || echo unit-missing ``` - **unit-installed**: enable and start it (user service — no sudo): ```bash systemctl --user enable --now linuxtoys-mcp.service systemctl --user is-active linuxtoys-mcp.service ``` - **unit-missing**: the unit is installed by the app when the user first …

How to install
mdr add psygreg/linuxtoys/linuxtoys-mcp@sha256:e56d312274b4cdc3The line at the top of this page pins the label git:20261030.a73a954, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
