  "mcpServers": {
    "analyst": {
      "command": "uvx",
      "args": [
        "mcp-analyst",
        "--file_location",

    }
  }
}
```

# How do I provide more than one CSV file?

The server supports the using globs in the file location. So for example if your directory `data` has more than one csv file then you can give file-location as `<parent_path_to_data>/data/*.csv`
