kde-mcp: computer-use for the Linux desktop
An MCP server that lets an agent actually drive a Linux (KDE Plasma 6 / Wayland) desktop. That's the kind of capability Anthropic ships for macOS and Windows, still rare on Linux. Built from scratch, solo, in Rust.
The bar before me
Computer-use tooling is mature on macOS and Windows, thin on Linux. What exists tends to lean on pixel-level screenshots and coordinate clicks, which are brittle and unsafe (a moved window or a re-theme breaks them). Wayland's security model makes naive screen-scraping harder still.
What I built
kde-mcp drives applications through the accessibility tree (the same structured interface a screen reader uses), not by clicking pixels. The agent acts on named, typed elements, so actions are more reliable and far easier to reason about and gate. A safety policy layer sits in front of destructive actions. Design decisions are written down as ADRs, not left living in my head.
