• Page and section breaks; page setup (margins, orientation, paper size, columns)
• Lists (bulleted/numbered)
• Tables: create, auto-fit, merge cells, alignment, shading, paddings, column widths, header styling
• Footnotes and endnotes: add, convert, anchor-based operations, validation
• Comments: get by author, by paragraph, all comments
• Document properties: read/write (title, author, subject, keywords)
• Protection: protect/unprotect, partial editing restrictions
• Bookmarks, hyperlinks
• Watermarks (text/image)
• Export as Base64 (DOCX, PDF, etc.), advanced export options
• Render page to image (PNG, etc.)
• In-memory document management: copy, save as, list, delete, merge

Requirements

• Python 3.11+
• Aspose.Words for Python via .Net. This library is a commercial product.
  You'll need to obtain a valid license for Aspose.Words. The package will install this dependency, but you're responsible for complying with Aspose's licensing terms.

Installation

pip install aspose-words-mcp

From source (download repo and install requirements):

git clone https://github.com/aspose-words/Aspose.Words-MCP-Server
cd Aspose.Words-MCP-Server
pip install -r requirements.txt

Command Line Interface

After installation, the CLI command is available:

aspose-words-mcp

By default, the server runs with the stdio transport.

Run without installation:

python mcp_server.py

Transports and Configuration

Supported MCP transports: stdio, streamable-http, sse.

Environment Variables

• MCP_TRANSPORT — stdio | streamable-http | sse (default stdio)
• MCP_HOST — host address (default 0.0.0.0)
• MCP_PORT — port (default 8080)
• MCP_PATH — HTTP path for streamable-http (default /mcp)
• MCP_SSE_PATH — events path for sse (default /sse)
• LOG_LEVEL — logging level (INFO, DEBUG, ...)

Aspose.Words License

The Aspose.Words license is applied when the server starts. The effective path to the license file is resolved with the following precedence:

1. The license_path argument of run_server(..., license_path=None)
2. The ASPOSE_WORDS_LICENSE_PATH environment variable

If no license is provided or the file is not accessible, the server runs in Evaluation mode.

Example of setting the environment variable:

export ASPOSE_WORDS_LICENSE_PATH='/path/to/aspose.words.lic'

HTTP/SSE Run Example

export MCP_TRANSPORT=streamable-http   # or sse
export MCP_HOST=0.0.0.0
export MCP_PORT=8080
export MCP_PATH=/mcp                   # for streamable-http
export MCP_SSE_PATH=/sse               # for sse
aspose-words-mcp

On start, the server prints the listening address.

Tools

See full list and signatures in mcp_server.py (function register_tools) and tests in tests/features/*.

Main tool categories:

• content/reading: create document, insert/delete/read text, headings, lists, HTML/Markdown
• layout: pages, breaks, columns, headers/footers, page numbering
• tables: create and format tables
• watermarks: watermarks
• links/bookmarks: hyperlinks and bookmarks
• properties: document properties
• protection: protection and restrictions
• comments/notes: comments, footnotes/endnotes
• export/render: export, page rendering

Example Workflow via an MCP Client

Sequence of tool calls (names match the server):

1. create_document → get doc_id
2. add_heading (e.g., levels 1–3)
3. add_paragraph / insert_text_end
4. add_table_end or add_table_at_paragraph
5. add_watermark_text or add_watermark_image_base64
6. export_base64 (e.g., fmt="pdf") — get file as Base64

Integration with MCP Clients

• Claude Desktop MCP: add this server with streamable-http or sse transport and the URL printed by the server at startup.
• Any MCP (JSON) clients — configure the matching transport and path.
