📊 Excel MCP Server

What is this project?

Excel MCP Server is a Model Context Protocol (MCP) server that allows Large Language Models (like Claude) to read, explore, and analyze Excel files. It provides tools for:

  • 📂 File Operations: Load Excel files, list sheets, get metadata

  • 🔍 Data Discovery: Analyze schemas, sample data, get column statistics

  • 📊 Analysis: Comprehensive dataset summaries and data quality reports

Built with FastMCP and pandas, it transforms your Excel files into interactive datasets that AI can understand and query.

Install Dependencies

# Set up environment (optional)
source activate-pipx.sh

# Install dependencies
uv sync

Requirements:

  • Python >=3.13

  • fastmcp >=2.10.6

  • pandas >=2.3.1

  • openpyxl >=3.1.5

  • xlrd >=2.0.2

  • pytest >=8.4.1

Start the MCP Server

python main.py

or

fastmcp run main.py:mcp --transport http --host 127.0.0.1 --port 8000 --path /mcp

The server will start and listen for MCP connections. You'll see output confirming the server is running.

Testing

# Run all tests
python -m pytest tests/ -v

# Run specific test files
python -m pytest tests/test_file_operations.py -v
python -m pytest tests/test_data_discovery.py -v

# With coverage
python -m pytest tests/ --cov=src --cov-report=html

Integrate with Claude

1. Claude Desktop Integration

Add to your Claude Desktop config file (claude_desktop_config.json):

{
  "mcpServers": {
    "excel-explorer": {
      "command": "python",
      "args": ["/path/to/excel-mcp/main.py"],
      "env": {}
    }
  }
}

or

{

    "excelExplorer": {
        "command": "npx",
        "args": [
            "-y",
            "mcp-remote",
            "http://127.0.0.1:8000/mcp"
        ],
        "env": {
            "MCP_TRANSPORT_STRATEGY": "http-only"
        }
    }
}

2. Available Tools

Once connected, Claude can use these tools:

File Operations:

  • load_excel(file_path, sheet_name) - Load Excel file

  • list_sheets(file_path) - List all sheets

  • get_file_info(file_path) - File metadata

  • clear_cache() - Clear memory

Data Discovery:

  • get_schema(file_path, sheet_name) - Column types and stats

  • get_sample_data(file_path, rows=5, sample_type="head") - Sample data

  • get_column_info(file_path, column_name) - Column analysis

  • get_dimensions(file_path) - Dataset size and memory

  • describe_dataset(file_path, include_all=False) - Statistical summary

3. Example Usage with Claude

You: "Load the file data/dataset.xlsx and tell me about its structure"

Claude will use:
1. load_excel("data/dataset.xlsx")
2. get_schema("data/dataset.xlsx")
3. get_dimensions("data/dataset.xlsx")
4. describe_dataset("data/dataset.xlsx")

Then provide insights about your data!
