From the README
# MCP Auth Proxy > If you found value here, please consider starring. ## Overview - **Drop-in OAuth 2.1/OIDC gateway for MCP servers — put it in front, no code changes.** - **Your IdP, your choice**: Google, GitHub, or any OIDC provider — e.g. Okta, Auth0, Azure AD, Keycloak — plus optional password. - **Flexible user matching**: Support exact matching and glob patterns for user authorization (e.g., `*@company.com`) - **Publish local MCP servers safely**: Supports all stdio, SSE, and HTTP transports. For stdio, traffic is converted to `/mcp`. For SSE/HTTP, it's proxied as-is. Of course, with authentication. - **Verified across major MCP clients**: Claude, Claude Code, ChatGPT, GitHub Copilot, Cursor, etc. — the proxy smooths client-specific quirks for consistent auth. --- 📖 **For detailed usage, configuration, and examples, see the [Documentation](https://sigbit.github.io/mcp-auth-proxy/)** ## Quickstart > Domain binding & 80/443 must be accessible from outside.
