Using Extensions

Goose Extensions are add-ons that provide are a way to extend the functionality of Goose. They also provide a way to connect Goose with applications and tools you already use in your workflow. These extensions can be used to add new features, automate tasks, or integrate with other systems.

Adding An Extension

You can expand Goose's capabilities by adding extensions. Built-in extensions are pre-installed with Goose, while external extensions can be integrated via Anthropic's Model Context Protocol (MCP).

**To add a Built-in, Command-line or Remote extension:**

1. run the following command:
```sh
goose configure
```
2. Select `Add Extension` from the menu.
3. Choose the type of extension you’d like to add:
    - `Built-In Extension`: Use an extension that comes pre-installed with Goose.
    - `Command-Line Extension`: Add a local command or script to run as an extension.
    - `Remote Extension`: Connect to a remote system via SSE (Server-Sent Events).
4. Follow the prompts based on the type of extension you selected.

```sh
