[Bug]: Atlassian MCP doesnt connect correctly

[the-mace]

Bug Description

Throws an error trying to connect:
Error adding MCP server: SSE transport error: AxiosError: Request failed with status code 404

Steps to reproduce

1. Use same command as claude code but with grok instead:
   grok mcp add --transport sse jira --url https://mcp.atlassian.com/v1/sse
2. With grok-cli it gives:

✓ Added MCP server: jira
Error adding MCP server: SSE transport error: AxiosError: Request failed with status code 404

No browser/auth window was opened.

Not sure if ~/.grok/user-settings.json is supposed to get the MCP config, but its not in there afterwards.

3. With claude code it completes as expected:

% claude mcp add --transport sse jira https://mcp.atlassian.com/v1/sse
Added SSE MCP server jira with URL: https://mcp.atlassian.com/v1/sse to local config
