+MCP GitHub Integration with Personal Access Token (PAT)
+
+This example demonstrates how to connect to GitHub's remote MCP server using a Personal Access
+Token (PAT) for authentication. The agent can use GitHub operations like searching repositories,
+reading files, creating issues, and more depending on how you scope your token.
+
+Prerequisites:
+1. A GitHub Personal Access Token with appropriate scopes
+   - Create one at: https://github.com/settings/tokens
+   - For read-only operations, you can use more restrictive scopes
+2. Environment variables:
+   - GITHUB_PAT: Your GitHub Personal Access Token (required)
+   - OPENAI_API_KEY: Your OpenAI API key (required)
+   - OPENAI_RESPONSES_MODEL_ID: Your OpenAI model ID (required)
