[FEATURE] MCP auth all

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet

Problem Statement

Same request as https://github.com/anthropics/claude-code/issues/12051 which was ignored

Feature Request: Sequential OAuth for Multiple MCP Servers
What is the problem
I have many oauth mcp servers and it gets annoying cycling through authentication for all of them
It would be nice to have a authenticate all option which just cycles through all enabled mcp servers and launches authentication flows for them

Priority

Proposed Solution

The following command:

/mcp authenticate_all

this cycles through all enabled mcp servers and launches oauth flows for them if not authenticated. It would also be cool if it can be invoked in the bash, since then I can have it as a hook on session start

Alternative Solutions

It can also be solved by allowing to refresh the mcp list in the claude desktop app

Priority

High - Significant impact on productivity

Feature Category

CLI commands and flags

Use Case Example

I often have bigger chats that needs to be reset because claude deskop doesn't update the mcp list in the existing chats which constantly interrupts my workflow. It would be good if I could actually rely on mcp that I already added and haven't disabled to be there
