It is in early development and may change significantly.\n\n## Why Wassette?\n\n- **Convenience**: Wassette makes it easy to extend AI agents with new tools,\n  all without ever having to leave the chat window.\n- **Reusability**: Wasm Components are generic and reusable;\n  there is nothing MCP-specific about them.\n- **Security**: Wassette is built on the Wasmtime security sandbox, providing\n  browser-grade isolation of tools.\n\n## Architecture\n\n![An architecture diagram showing the relationship between Wassette, MCP Clients, and Wasm Components](./assets/architecture.png)\n\n## Installation\n\n**Quick start:** For Linux/macOS, use our one-liner install script:\n\n```bash\ncurl -fsSL https://raw.githubusercontent.com/microsoft/wassette/main/install.sh | bash\n```\n\n**For complete installation instructions** for all platforms (including Windows, Homebrew, Nix, Docker, and more), see our **[Installation Guide](https://microsoft.github.io/wassette/latest/installation.html)**.\n\n## Using Wassette\n\nWith Wassette installed, the next step is to register it with your agent of choice. See our [Quick Start] guide (3 simple steps), or check the [MCP Clients guide](https://microsoft.github.io/wassette/latest/mcp-clients.html) for detailed setup instructions for GitHub Copilot, Cursor, Claude Code, and Gemini CLI.\n\nOnce configured, you can start loading WebAssembly components. To teach your agent to tell the time, ask it to load a time component:\n\n```text\nPlease load the time component from oci://ghcr.io/microsoft/time-server-js:latest\n```\n\nNow that the time component is loaded, we can ask your agent to tell you the current time:\n\n```text\nWhat is the current time?\n```\n\nThe agent will respond with the current time, which is fetched from the time component running in a secure WebAssembly sandbox:\n\n```output\nThe current time July 31, 2025 at 10:30 AM UTC\n```\n\nCongratulations! You've just run your first Wasm Component and taught your agent how to tell time!\n\n## Demo\n\nhttps://github.com/user-attachments/assets/8e5a371c-ac72-406d-859c-03833ee83963\n\n## Discord\n\nYou can join us via the `#wassette` channel on the [Microsoft Open Source Discord](https://discord.gg/microsoft-open-source):\n\n[![Microsoft Open Source Discord](https://dcbadge.limes.pink/api/server/microsoft-open-source)](https://discord.gg/microsoft-open-source)\n\n## Contributing\n\nPlease see [CONTRIBUTING.md][Contributing] for more information on how to contribute to this project.\n\n## License\n\nThis project is licensed under the \u003ca href=\"LICENSE\"\u003eMIT License\u003c/a\u003e.\n\n## Trademarks\n\nThis project may contain trademarks or logos for projects, products, or services.
