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 Quickstart Domain binding & 80/443 must be accessible from outside.

Your HTTP endpoint is now available at https://{your-domain}/mcp . - stdio (when a command is specified): MCP endpoint is https://{your-domain}/mcp. - SSE/HTTP (when a URL is specified): MCP endpoint uses the backend’s original path (no conversion). Already have certificates? Pass --tls-cert-file and --tls-key-file instead of --tls-accept-tos .
