Claude Code MCP Deep Dive (6): From One Authorization to Multiple Servers

Claude Code manages remote MCP server authentication via browser-based OAuth, allowing secure credential retention and token refreshing. In enterprise environments with Cross-App Access, a single identity provider login can grant access to multiple servers. Separately, a comparison of ComfyUI MCP servers reveals that comfyui-mcp offers the widest features, comfy-mcp provides official support, and comfyui-mcp-secure minimizes local file system exposure. All three utilize stdio transport, differing primarily in file access and model context consumption.
