Adding custom MCP server leads to error.

While digging deeper into Rovodev, I wonder if connecting custom MCP server is already supported and how to achieve this?

 

I read  https://rovodevagents-beta.atlassian.net/wiki/external/Yzc2NzI4MTk3YTBhNDdiYjkzZDhhZTc3MjE0ZmE4Y2Q#Model-Context-Protocol-(MCP)-servers about the ~/.rovodev/mcp.json config file.

 

I've configured my local MCP server as follows:

 

{
  "mvg_stoerung": { 
     "command": "python3", 
     "args": ["mvg_mcp_server.py"], 
     "cwd": "/Users/rmoriz/Sync/Projekte/mvg_stoerung_mcp"
  } 
}

 

However, when I restart Rovodev, the following error appears:

 

╭─ Could not parse user-defined MCP configuration ─────────────────────────────────────────────────────────────────────╮

Ah, looks like the file has to be in the same format as other vendors do:

 

{
"mcpServers": {
  "mvg-stoerung": {
     "command": "python3",
      "args": ["mvg_mcp_server.py"],
      "cwd": "/path/to/mvg_stoerung_mcp"
     }
   }
}
