Workflows support **GitHub Copilot** (default), **Claude by Anthropic**, **Codex**, and **Gemini by Google**. Each [engine](/gh-aw/reference/engines/) (AI model/provider) interprets natural language instructions and executes them using configured tools and permissions.

Each engine authenticates with its own secret or permission:

| Engine | Frontmatter `engine:` | Secret or permission required |
|---|---|---|
| Copilot (default) | `copilot` | [`copilot-requests: write`](/gh-aw/reference/auth/#copilot-requests-write-permission) permission or [`COPILOT_GITHUB_TOKEN`](/gh-aw/reference/auth/#copilot_github_token) |
| Claude | `claude` | [`ANTHROPIC_API_KEY`](/gh-aw/reference/auth/#anthropic_api_key) |
| Codex | `codex` | [`OPENAI_API_KEY`](/gh-aw/reference/auth/#openai_api_key) (or `CODEX_API_KEY`) |
| Gemini | `gemini` | [`GEMINI_API_KEY`](/gh-aw/reference/auth/#gemini_api_key) |

See [Authentication](/gh-aw/reference/auth/) for the full setup instructions for each engine.

## Tools and Model Context Protocol (MCP)

Workflows use [tools](/gh-aw/reference/tools/) through the **[Model Context Protocol](/gh-aw/reference/glossary/#mcp-model-context-protocol)** (MCP, a standardized protocol for connecting AI agents to external tools and services) for GitHub operations, external APIs, file operations, and custom integrations.
