Unable to establish connection between Atlassian MCP-server & github copilot in VS code

[Andew Carsten]

I tried to connect Atlassian MCP-server through github copilot in VS code but not able to do it.

"mcp": {

  "servers": {

    "atlassian": {

       "url": "https://mcp.atlassian.com/v1/sse",

       "transport": "sse",

       "command": "mcp-atlassian",

       "args": [

           "--jira-url", "https://your-company.atlassian.net",

           "--jira-username", "your.email@company.com",

           "--jira-token", "your_api_token",

           "--confluence-url", "https://your-company.atlassian.net/wiki",

           "--confluence-username", "your.email@company.com",

           "--confluence-token", "your_api_token"
        ],

      "env": {},

      "disabled": false

       }
   }
}

Tried with this code but getting this following error while running the server

Can someone provide me a solution for this.

Quiet impressive how much Atlassian is failing behind on the AI world, it's very frustrating as this prevents our company to move forward.

i was facing the same issue.  i was using nvm version 12.

My issue got resolved when i switched to nvm version 18. Any other version lower than that I kept getting some error.

please try and update if this resolves your error.
