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.

Actual Behavior
It returned 401

I'm running into similar issues setting up Linear in Cursor, and as you wrote it was working for you in Cursor, how did you set it up? I followed their instructions but get these errors as well:
config
errors
I am having the same issue running Claude Code on Windows 11 in WSL on a snapdragon X-Elite laptop.
I have a workaround for this issue with the following
npm install -g mcp-remotemcp-remote https://mcp.linear.app/ssego through the auth process so it can be cachedclaude mcp add linear mcp-remote https://mcp.linear.app/sseclaude --debugcode up and should see success logsWhen in doubt. MCP remote. lol unfortunately. But it seems to be getting better.
Would like to see this prioritized; it's been nearly 3 months
And another month has gone by without this being addressed
Checks notes It's still broken. This is so annoying cuz if you're remote you think it just doesn't work. You can also just use API keys btw with this solution

It is EXTREMELY disappointing that Anthropic doesn't understand how important this issue is in corporate environments. Not resolving this since MAY 2025 is insane.

This issue was closed incorrectly despite recent human comments. This behavior of the bot is reported at https://github.com/anthropics/claude-code/issues/16497. Please upvote that issue, so maybe it gets noticed.
Both the bot's behavior in closing this prematurely and Anthropic ignoring this enterprise important feature is disappointing
