  • goto preferences > settings > mcp and copy paste claude config
{
  "mcpServers": {
    "weather": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "C:\\Users\\Suraj\\Desktop\\Python\\mcp-crash-course\\mcpcrashcourse\\server\\weather.py"
      ]
    }
