The skill uses Docker to run the official GitHub MCP server:

Image:
```
ghcr.io/github/github-mcp-server

Auth:
```
GITHUB_PERSONAL_ACCESS_TOKEN
```
environment variable

Environment Variables

Variable	Required	Description
`GITHUB_PERSONAL_ACCESS_TOKEN`	Yes	GitHub PAT for authentication
`GITHUB_HOST`	No	For GitHub Enterprise (default: github.com)
`GITHUB_TOOLSETS`	No	Comma-separated toolsets to enable
`GITHUB_READ_ONLY`	No	Set to 1 for read-only mode

Limiting Toolsets

When using MCP, configure toolsets via environment variables:

# Only repos and issues
GITHUB_TOOLSETS=repos,issues

# Only pull requests and code security
GITHUB_TOOLSETS=pull_requests,code_security

Error Handling

If operations fail:

Verify Docker is running:
```
docker ps
```
Check GitHub token is set:
```
echo $GITHUB_PERSONAL_ACCESS_TOKEN
```
Ensure token has required permissions for the operation
Use
```
gh auth status
```
