Install the binary to ~/.local/bin
Configure your shell PATH for immediate access

Homebrew

If you prefer using Homebrew on Linux:

nix profile install github:microsoft/wassette

# Or use in a development shell
nix develop github:microsoft/wassette

This provides a reproducible environment for using and developing Wassette.

Configure with your AI agent: Follow the MCP clients setup guide for instructions on integrating Wassette with:
- Visual Studio Code
- Cursor
- Claude Code
- Gemini CLI
Install agent instructions (Recommended): Add Wassette-specific instructions to your agent’s documentation to ensure proper permission management:
```
curl https://raw.githubusercontent.com/microsoft/wassette/main/rules/agent.md >> AGENTS.md
```
This adds important guidelines that help AI agents correctly use Wassette’s permission tools instead of manually editing policy files.
Load your first component: Try loading a sample component to verify everything works:
