### Description (declared)

# Excel Tools MCP

Excel Tools MCP is a standalone Model Context Protocol server for reading and inspecting local
Excel files. It is designed for AI assistants that need a compact, structured view of spreadsheets
without loading an entire workbook into context.

The project supports two distribution paths:

- npm / npx: a Node.js launcher starts the Python MCP server.
- PyPI / uvx / pip: run the Python MCP server directly.

Only local file paths are supported.

## Version Status

### Published v0.1.0

The first published release supports `.xlsx` files through `openpyxl`.

Available tools:

- `excel_inspect`: inspect workbook metadata and sheet dimensions.
- `excel_read_range`: read a rectangular cell range.
- `excel_profile_structure`: summarize row structure patterns.

Known boundary:

- `.xls` is not supported in v0.1.0.

### Published v0.1.1

New and changed behavior:

- Read-only tools support `.xlsx`, `.xlsm`, `.xls`, `.xlsb`, and `.ods`.
- `.xlsx` and `.xlsm` are read with `openpyxl`.
- `.xls`, `.xlsb`, and `.ods` are read with `python-calamine`.
- `excel_read_range_normalized` reads a range and virtually fills merged cells from their anchor
  values without modifying the file.

Available tools in v0.1.1:

- `excel_inspect`: inspect workbook metadata and sheet dimensions.
- `excel_read_range_normalized`: read a rectangular range, analyze merged cells, and optionally
  return anchor-filled data.
- `excel_profile_structure`: summarize row structure patterns and merged-cell structure.

## Run With npx

This is the easiest route for MCP clients that already support Node-based server launch commands.

```json
{
  "mcpServers": {
    "excel-tools-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": ["--yes", "@wasziyang/excel-tools-mcp"]
    }
  }
}
```

Requirements:

- Node.js 20+
- Python 3.10+

The npm package is a launcher. It creates or reuses a cached Python environment, installs the Python
MCP server, and starts it over stdio.
