MCP Unknown Tool

[CPR03]

I have this MCP error, and I cannot tell what is causing this issue. MCPs works yesterday now it does not. Both DBCode and Tavily does not work.

Here is my configuration:

{
    "mcpServers": {
        "tavily-mcp": {
            "command": "cmd",
            "args": ["/c", "npx -y [email protected]"],
            "env": {
                "TAVILY_API_KEY": "xxxxxxxxxxxx"
            }
        },
        "console-ninja": {
            "command": "node",
            "args": ["~/.console-ninja/mcp/"]
        },
        "dbcode": {
            "url": "http://localhost:5002/sse"
        },
        "■■■■■.build": {
            "url": "xxxxxxxxxxxxx"
        }
    }
}

I can confirm that with the same MCP configuration it works on other AI chat tools. I think this is a cursor bug? I am not sure.

I have the same issue. Works like charm in Roo Cline. In Cursor sometimes yes, but mostly no with the same error. I have tried all permutations - cmd /c, only npx, etc…
