How to Set Up and Use Claude Code Rust
Claude Code Rust is a high-performance reimplementation of the Claude Code environment built with Rust and Tauri, offering 2.5x faster startup times and a binary size that is 97% smaller than the original. It provides a full-featured desktop GUI with a three-column workspace — file tree, Monaco editor, and live preview — alongside a lightweight CLI for terminal REPL interaction. Developers who want a snappier AI coding assistant experience with lower resource overhead will find this a compelling alternative to the stock Claude Code installation.
Prerequisites
- Rust 1.75 or higher installed via rustup (for CLI build)
- Node.js 18+ and npm (for the Tauri GUI version)
- An Anthropic API key (ANTHROPIC_API_KEY)
- Platform build tools: Xcode CLI on macOS, Visual Studio C++ Build Tools + WebView2 on Windows, libwebkit2gtk-4.1-dev + libgtk-3-dev on Linux
- An MCP-compatible client such as Claude Desktop
Clone the repository
Clone the claude-code-rust repository from GitHub to get the source code for both the CLI and GUI variants.
git clone https://github.com/lorryjovens-hub/claude-code-rust.git
cd claude-code-rustSet your Anthropic API key
Export the ANTHROPIC_API_KEY environment variable, or create a .env file in the project root. The API_BASE_URL defaults to the Anthropic endpoint but can be overridden if you use a proxy.
export ANTHROPIC_API_KEY="your-api-key"
export API_BASE_URL="https://api.anthropic.com"Build the CLI binary
Compile the Rust CLI in release mode. The resulting binary is under 5 MB and starts noticeably faster than Node-based alternatives.
cargo build --release
./target/release/claude-code --versionBuild the Tauri GUI (optional)
If you prefer the full desktop GUI with Monaco editor, file tree, and terminal tabs, install Node dependencies inside the Tauri sub-directory and build.
cd claude-desktop-tauri
npm install
npm run tauri buildConfigure as an MCP server
Add the compiled CLI binary as an MCP server in your Claude Desktop configuration file so AI clients can invoke it.

}Prompts to try
Example prompts once the server is connected to a Claude Desktop session.
- "Open the project at ~/my-app and show me the file tree"
- "Run the build command and stream the output to me"
- "Show a git diff of unstaged changes in the current repo"
- "Open a new terminal tab and run the test suite"Troubleshooting Claude Code Rust
cargo build fails with linker errors on Linux
Install the required system libraries: sudo apt-get install libwebkit2gtk-4.1-dev libgtk-3-dev libssl-dev pkg-config, then retry the build.
API key not recognized at runtime
Ensure ANTHROPIC_API_KEY is set in the env block of your MCP config, or create a .env file in the same directory as the binary. Environment variables exported in your shell are not automatically inherited by MCP clients.
Tauri GUI shows a blank white window on Linux
WebKit2GTK is required for the GUI renderer. Install libwebkit2gtk-4.1-dev and ensure a display server is running (Wayland or X11). Running WEBKIT_DISABLE_COMPOSITING_MODE=1 before launching can also help.
