Quick Start First, add the Document Operations MCP server to your MCP client. **Standard config** works in most MCP clients: ```json { "mcpServers": { "doc-ops-mcp": { "command": "npx", "args": ["-y", "doc-ops-mcp"], "env": { "OUTPUT_DIR": "/path/to/your/output/directory", "CACHE_DIR": "/path/to/your/cache/directory", } } } } ```

Claude Desktop

Follow the MCP install [guide](https://modelcontextprotocol.io/quickstart/user), use the standard config above.

VS Code

Follow the MCP install [guide](https://code.visualstudio.com/docs/copilot/chat/mcp-servers#_add-an-mcp-server), use the standard config above.

Cursor

Go to `Cursor Settings` -> `MCP` -> `Add new MCP Server`. Name to your liking, use `command` type with the command `npx -y doc-ops-mcp`.

Other MCP Clients

For other MCP clients, use the standard config above and refer to your client's documentation for MCP server installation.

### Configuration The Document Operations MCP server supports configuration through environment variables. These can be provided in the MCP client configuration as part of the `"env"` object: ```json { "mcpServers": { "doc-ops-mcp": { "command": "npx", "args": ["-y", "doc-ops-mcp"], "env": { "OUTPUT_DIR": "/path/to/your/output/directory", "CACHE_DIR": "/path/to/your/cache/directory", "WATERMARK_IMAGE": "/path/to/watermark.png", "QR_CODE_IMAGE": "/path/to/qrcode.png" } } } } ``` ### Supported Document Operations | Format | Convert to PDF | Convert to DOCX | Convert to HTML | Convert to Markdown | Content Rewriting | Watermark/QR Code | |--------|----------------|-----------------|-----------------|---------------------|-------------------|-------------------| | **PDF** | ✅ | ❌ | ❌ | ❌ | ❌ | ✅ | | **DOCX** | ✅ | ✅ | ✅ | ✅ | ✅ | ❌ | | **HTML** | ✅ | ❌ | ✅ | ✅ | ✅ | ❌ | | **Markdown** | ✅ | ✅ | ✅ | ✅ | ✅ | ❌ | **Rewriting Features:** - **Content Replacement**: Support batch text replacement and regular expression replacement - **Format Adjustment**: Modify document structure, heading levels, and style formatting - **Smart Rewriting**: Content optimization while preserving original document format ### Usage Examples **Format Conversion:** ``` Convert /Users/docs/report.docx to PDF Convert /Users/docs/article.md to HTML Convert /Users/docs/presentation.html to DOCX Convert /Users/docs/readme.md to PDF (with theme styling) ``` **Document Rewriting:** ``` Rewrite company names in /Users/docs/contract.md Batch replace terminology in /Users/docs/manual.docx Adjust heading levels in /Users/docs/article.html Update dates and version numbers in /Users/docs/policy.md ``` **PDF Enhancement:** ``` Add watermark to /Users/docs/document.pdf Add QR code to /Users/docs/report.pdf Add company logo watermark to /Users/docs/invoice.pdf ``` ### Environment Variables The server supports environment variables for controlling output paths and PDF enhancement features: #### Core Directories - **`OUTPUT_DIR`**: Controls where all generated files are saved (default: `~/Documents`) - **`CACHE_DIR`**: Directory for temporary and cache files (default: `~/.cache/doc-ops-mcp`) #### PDF Enhancement Features - **`WATERMARK_IMAGE`**: Default watermark image path for PDF files - Automatically added to all PDF conversions - Supported formats: PNG, JPG - If not set, default text watermark "doc-ops-mcp" will be used - **`QR_CODE_IMAGE`**: Default QR code image path for PDF files - Added to PDFs only when explicitly requested (`addQrCode=true`) - Supported formats: PNG, JPG - If not set, QR code functionality will be unavailable **Output Path Rules:** 1. If `outputPath` is not provided → files saved to `OUTPUT_DIR` with auto-generated names 2. If `outputPath` is relative → resolved relative to `OUTPUT_DIR` 3. If `outputPath` is absolute → used as-is, ignoring `OUTPUT_DIR` See [OUTPUT_PATH_CONTROL.md](./OUTPUT_PATH_CONTROL.md) for detailed documentation. ## 2. System Architecture Document Operations MCP Server adopts a pure JavaScript architecture design, providing complete document processing capabilities: ``` ┌─────────────────────────────────────────────────────────────┐ │ MCP Client Layer │ │ (Claude Desktop, Cursor, VS Code, etc.) │ └─────────────────────┬───────────────────────────────────────┘ │ JSON-RPC 2.0 ┌─────────────────────┴───────────────────────────────────────┐ │ Doc-Ops-MCP Server │ │ ┌─────────────────┐ ┌─────────────────┐ ┌─────────────┐ │ │ │ Tool Router │ │ Request │ │ Response │ │ │ │ & Handler │ │ Validator │ │ Formatter │ │ │ └────────┬────────┘ └────────┬────────┘ └──────┬──────┘ │ │ │ │ │ │ │ ┌────────┴────────────────────┴──────────────────┴─────┐ │ │ │ Document Processing Engine │ │ │ │ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ │ │ │ │ Document │ │ Format │ │ Style │ │ │ │ │ │ Reader │ │ Converter │ │ Processor │ │ │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ │ │ │ │ │ │ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ │ │ │ │ PDF │ │ Watermark/ │ │ Conversion │ │ │ │ │ │ Enhancement │ │ QR Code │ │ Planner │ │ │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ └────┴───────────────────────────────────────────────────────┴─┘ │ ┌───────────────────────────┴─────────────────────────────────┐ │ Core Dependencies Layer │ │ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ │ │ pdf-lib │ │word-extractor│ │ marked │ │ │ │ (PDF Tools) │ │(DOCX Reader)│ │ (Markdown) │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ │ │ cheerio │ │ jszip │ │ docx │ │ │ │(HTML Parser)│ │(ZIP Handler)│ │(DOCX Gen.) │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ │ │ ┌─────────────┐ ┌─────────────┐ │ │ │ xml2js │ │Custom OOXML │ │ │ │(XML Parser) │ │ Parser │ │ │ └─────────────┘ └─────────────┘ │ └─────────────────────────────────────────────────────────────┘ ``` ### Architecture Overview **Core Features**: - Pure JavaScript implementation with no external system dependencies - Complete document reading, conversion, and style processing capabilities - Built-in PDF watermark and QR code addition functionality - Intelligent conversion planning and path optimization **Conversion Flow**: - **Direct Conversion**: Supports direct conversion between most formats - **Multi-step Conversion**: Complex conversions achieved through intermediate formats - **Style Preservation**: Uses OOXML parser to ensure complete style integrity ## 3.
