Bug Description

Claude Code MCP authentication doesn't work in SSH remote sessions.

I was testing linear MCP, and the authentication worked locally. However, when I joined through an SSH session to my Remote Development Environment using SSH, the authentication process didn't work as there was no way to access a browser remotely.

linear:
  Scope: Local (private to you in this project)
  Type: stdio
  Command: npx -y mcp-remote https://mcp.linear.app/sse
  Args:
  Environment:

These are the mcp-logs:

[
  {
    "error": "Connection failed: spawn npx -y mcp-remote https://mcp.linear.app/sse ENOENT",
    "timestamp": "2025-05-19T19:43:39.452Z",
    "sessionId": "2ef38d86-08ff-4331-b58c-91b977b6d207",
    "cwd": "/home/owner/src/..."
  }
]

When I try to connect using SSE instead of stdio, it returns 401.

The same setup worked in Cursor and the Claude desktop, since they are all local.

Steps to Reproduce

1. Connect to a remote server using ssh <!-- First step -->
2. Add an MCP that requires OAuth Authentication<!-- Second step -->
3. Run claude<!-- And so on... -->

Expected Behavior

I expect a prompt similar to AWS auth, which tries to open locally, but since it's an SSH connection, it also allows me to add the authorization token
<!-- What you expected to happen -->

Actual Behavior

It returned 401
