Installation

Community Nodes (Recommended)

1. Go to Settings > Community Nodes
2. Select Install

4. Confirm the installation

Manual Installation

cd ~/.n8n/nodes

Authentication

This node requires a GitHub Personal Access Token (PAT) with appropriate permissions.

Getting a GitHub Token

1. Go to GitHub Settings > Developer settings > Personal access tokens
2. Generate a new token (classic) with the following scopes:
   • read:user - For basic authentication validation
   • For GitHub Copilot access, you need an active Copilot subscription
3. Copy the token and use it in the n8n credentials

Alternative: GitHub Models API

For broader model access, you can use the GitHub Models platform:

1. Visit GitHub Models
2. Get access to the models you want to use
3. Use your GitHub PAT for authentication

1. Read File - Get source code files
2. GitHub Copilot - Generate documentation
3. Write File - Save documentation

Example: Test Generation Pipeline

1. Watch Folder - Monitor for new code files
2. Read File - Get file contents
3. GitHub Copilot - Generate tests
4. Write File - Save test files
5. Execute Command - Run tests

Error Handling

The node includes comprehensive error handling:

• Invalid credentials are caught during execution
• API rate limits are reported with clear messages
• Model-specific errors are passed through

Enable "Continue On Fail" to process multiple items even if some fail.
