Create Claude Desktop MCP config

Path: ~/Library/Application Support/Claude/claude_desktop_config.json
Add an entry for this server (adjust cwd to your project path):

{
  "mcpServers": {
    "excel": {
      "command": "node",
      "args": ["/Users/macbook/Projects/mcp_excel/dist/index.js"],
      "env": { "LOG_LEVEL": "info" }
    }
  }
}

Restart Claude Desktop

Quit and reopen Claude Desktop so it loads the new MCP server.

Verify server is detected

In Claude Desktop, open Settings → MCP Servers and confirm excel is listed and connected.

Example chat with Claude

In a new chat, say:
- "Use the excel MCP to open my workbook at '/absolute/path/to/your.xlsx' using open_workbook."
- "Then list worksheets."
- "Read cell A1 on 'Sheet1'."
- "Read range A1:C3 on 'Sheet1'."

If the file exists and is readable, Claude will call these tools and return results. Use absolute paths.
