MCP Wrapper for Multi-User OAuth Authentication

Turns a stdio MCP server into a multi-user remote MCP server authenticated via OAuth.

MCP Wrapper for Multi-User OAuth Authentication

This tool, the MCP Wrapper for Multi-User OAuth Authentication, is designed to enhance the security and usability of standard MCP servers. By integrating OAuth, it transforms a single-user, stdio-based MCP server into a robust multi-user platform. This allows for secure, authenticated access for multiple developers, streamlining collaborative development workflows and managing access permissions effectively. The wrapper acts as an intermediary, handling the OAuth authentication process before forwarding requests to the underlying MCP server.

What it Does

The MCP Wrapper takes a standard MCP server that typically runs via stdio and enables it to support multiple users. It achieves this by implementing an OAuth 2.0 authentication layer. When a user attempts to connect, the wrapper intercepts the request and guides them through an OAuth flow. Upon successful authentication, the user is granted access to the MCP server. This effectively turns a single-instance, potentially insecure server into a controlled, multi-tenant environment.

Key Features

Multi-User Support: Enables concurrent access for multiple authenticated users.
OAuth 2.0 Authentication: Leverages industry-standard OAuth for secure user verification.
stdio MCP Server Integration: Designed to work with existing stdio-based MCP server implementations.
Remote Access: Facilitates secure remote access to MCP server functionalities.
Access Control: Implicitly provides a foundation for managing user access based on OAuth credentials.

Who it's For

This tool is specifically for developers working with MCP servers who require a more secure and scalable solution for team collaboration. It is ideal for projects where multiple developers need to interact with the same MCP instance remotely. If you are managing an MCP server and need to grant access to a team, or if you are building applications that rely on MCP functionalities and want to integrate them into a multi-user environment, this wrapper provides the necessary authentication and access management capabilities.
