Overview
An MCP server demonstrating Google OAuth2 authentication using the device flow for securing access to tools and resources.
Installation
cd examples/oauth && go build && ./oauthEnvironment Variables
- GOOGLE_CLIENT_ID
- GOOGLE_CLIENT_SECRET
Security Notes
The server correctly leverages environment variables for Google OAuth2 client ID and secret, avoiding hardcoded credentials in the example. It uses a robust OAuth2 device flow for authentication and integrates bearer token validation at the HTTP layer. The default binding to 'localhost' limits direct network exposure. The README explicitly highlights critical production considerations such as requiring HTTPS, proper token storage, and refresh token handling. While the example's tool handlers currently return placeholder user information due to the handler signature not yet supporting context passing, the authentication mechanism itself functions correctly at the HTTP middleware level.
