Install

Prerequisites

• Rust, via rustup. glass pins a nightly toolchain in rust-toolchain.toml; rustup installs it automatically on the first build.
• A display dependency for your backend:
  • Linux / X11 (default): the headless X server — sudo apt-get install -y xvfb.
  • Linux / Wayland: a discoverable sway ≥ 1.12 plus Mesa software GL.
  • Windows: nothing extra; glass uses built-in Windows APIs.
  • Android (AVD): the Android SDK platform-tools (adb) plus an emulator/AVD — glass drives the app over adb from a Linux or Windows host.
• A containment runtime (desktop apps are sandboxed by default):
  • Linux: bubblewrap with unprivileged user namespaces enabled.
  • Windows: Sandboxie Classic with its service running.
  • Android: none to install — the app runs inside the emulator/AVD, which isolates it from your host.

Build from source

git clone https://github.com/fixed-width/glass
cd glass
cargo build --release -p glass-mcp        # → target/release/glass-mcp

Tagged releases also attach prebuilt binaries to the GitHub Releases page.

Verify

./target/release/glass-mcp doctor    # checks the environment, with a remedy for any gap
