Quick Start

MCP Configuration

Add to your MCP client configuration (e.g., Claude Desktop, Cline, etc.):

Via npx (recommended):

{
  "mcpServers": {
    "docsmith": {
      "command": "npx",
      "args": ["-y", "docsmith-mcp"],
      "env": {
        "DOC_PAGE_SIZE": "100"
      }
    }
  }
}

Via global installation:

npm install -g docsmith-mcp

{
  "mcpServers": {
    "docsmith": {
      "command": "docsmith-mcp",
      "env": {
        "DOC_PAGE_SIZE": "100"
      }
    }
  }
}

Via local path:

{
  "mcpServers": {
    "docsmith": {
      "command": "node",
      "args": ["/path/to/docsmith-mcp/dist/index.js"]
    }
  }
}

Then use the read_document tool:

{
  "file_path": "/path/to/document.xlsx",
  "mode": "paginated",
  "page": 1,
  "page_size": 50
}

The MCP App will automatically open to display the document content beautifully.
