Usage

Using as an MCP Service in Cursor

1. Open Cursor and go to Settings
2. Find the Features > MCP Servers section
3. Click Add new MCP server
4. Fill in the following information:
   • Name: MCP_DOCX
   • Type: Command
   • Command: python3 /path/to/MCP_dox/server.py (replace with the actual path to your server.py)
5. Click Add to add the service

After adding, you can use natural language to operate Word documents in Cursor’s AI assistant, for example:

• “Create a new Word document and save it to the desktop”
• “Add a level 3 heading”
• “Insert a 3x4 table and fill it with data”
• “Set the second paragraph to bold and center-aligned”
