Securing your MCP servers

The evolution of the Box MCP server from using a simple STDIO transport protocol to supporting HTTP and Server-Sent Events (SSE) has necessitated a complex, yet purposeful dual authentication system that separates MCP client authentication from Box API authentication. This architectural decision enhances flexibility by catering to different deployment scenarios, such as specialized agents that access specific Box content regardless of the user and personal assistants that allow users to manage their individual Box files. The implementation of the OAuth 2.1 Protected Resource pattern (RFC 9728) allows the MCP server to integrate with enterprise APIs like Box, supporting a variety of authentication methods, including token-based and OAuth 2.1 flows. The complexity of maintaining dual authentication serves to protect infrastructure and data by establishing distinct trust boundaries, and the system's adaptability is further demonstrated through its compatibility with various OAuth configurations. As enterprises face increasing demands for robust multi-user and multi-server setups, the use of authentication proxies is suggested to centralize credential management and streamline access control. The document emphasizes that while the Box MCP server's authentication architecture is tailored to specific needs, it invites community collaboration to refine these strategies in the broader MCP ecosystem.
