Failing to connect to Blazorise MCP

[John Rees]

I'm attempting to add Blazorise MCP to Rovo Dev. Blazorise docs give this as an example of the mcp entry

{
  "servers": {
    "blazorise-docs": {
      "type": "http",
      "url": "https://mcp.blazorise.com/mcp/sse"
    }
  }
}

Obviously this doesn't quite match with the example given for Rovo Dev's mcp.json, so this is my attempt at adding it into mcp.json

{
  "mcpServers": {
    "blazorise-docs": {
      "url": "https://mcp.blazorise.com/mcp/sse",
      "transport": "sse"
    }
  }
}

When running Rovo Dev it attempts to connect to the mcp server but gives this error message.

Traceback (most recent call last):
  File "mcp\client\sse.py", line 105, in sse_reader
  File "anyio\_backends\_asyncio.py", line 708, in started
RuntimeError: called 'started' twice on the same task status
─── MCP Server Authentication Failed ───────────────────────────────────────────────────────────────────────────────────

Failed to start HTTP MCP server: blazorise-docs (url: https://mcp.blazorise.com/mcp/sse)

Authentication failed for the MCP server. Please check your credentials and try again.

Tools from this server will not be available.

The Blazorise support team have confirmed that their MCP does not require authorisation.

This has been resolved by the Blazorise team, it was an issue with their server.
