How are you running AnythingLLM?

AnythingLLM desktop app

What happened?

Hello all,
As per the documentation SSE MCP's are supported but when I add them, they are getting recognized but for each of them I get a 401 Unauthorized error. Failed to start MCP server: Atlassian MCP [401] SSE error: Non-200 status code (401)

Is there some setup I am missing?

The expectation was that there would be an oauth flow triggered to connect these servers.

Are there known steps to reproduce?

This is my mcp config:

{
  "mcpServers": {
    "GitHub MCP": {
        "url": "https://api.githubcopilot.com/mcp/",
        "type": "sse"
    },
    "Atlassian MCP": {
        "url": "https://mcp.atlassian.com/v1/sse",
        "type": "sse"
    }
  }
}

We do not trigger or pass through an OAuth flow. So in order to facilitate this you should be using env configs for the credentials to connect
