Authful MCP Proxy
by stephaneberle9
Adds an OAuth/OIDC authentication layer to remote MCP servers that lack built-in auth flows.
What it does
Acts as a secure bridge between MCP clients and remote MCP servers protected by token validation. It handles the full OIDC authentication flow (including browser-based login and PKCE), caches credentials locally, and automatically refreshes tokens.
Tools
This is a proxy server; it exposes the tools of the upstream MCP server it is configured to bridge to.
