Word MCP Server

Based on Office-Word-MCP-Server by GongRzhe – all credit for the core implementation goes to the original author.

Setup

./start_server.sh

Creates a .venv (using python3.12), installs dependencies from requirements.txt, and starts the server on port 8000 via streamable HTTP.

Related MCP server: docx-mcp-server

Deployment to Docker host

./deploy_to_remote.sh user

Syncs the server via rsync to the Docker host and builds/starts the container via docker compose.

MCP Registration

# Docker / remote
claude mcp add --scope user --transport http word http://<docker-host>:8000/mcp

# Local
claude mcp add --scope user --transport http word http://127.0.0.1:8000/mcp

File Transfer

The server runs in Docker and cannot access local file paths (e.g. /Users/…). Files must be uploaded via HTTP before they can be used with MCP tools.

Files are stored in /app/docx_files inside the container (mapped to /mnt/dockershare/word).

# Upload (required before any tool that takes a filename)
curl -s -H "X-API-Key: $MCP_API_KEY" -F "file=@document.docx" http://<docker-host>:8000/upload
# → returns JSON with "filename": "document.docx"

# Download
curl -H "X-API-Key: $MCP_API_KEY" http://<docker-host>:8000/download/document.docx -o document.docx

# List files
curl -H "X-API-Key: $MCP_API_KEY" http://<docker-host>:8000/files

# Delete single file
curl -X DELETE -H "X-API-Key: $MCP_API_KEY" http://<docker-host>:8000/files/document.docx

# Delete all files
curl -X DELETE -H "X-API-Key: $MCP_API_KEY" http://<docker-host>:8000/files

Workflow for agents

1. Upload the local file via curl -s -H "X-API-Key: $MCP_API_KEY" -F "file=@/path/to/file.docx" http://<docker-host>:8000/upload

2. Use the returned filename (e.g. "document.docx") with all Word tools

3. Do NOT try to read or unzip DOCX files locally — always upload via curl first

API Key

Set MCP_API_KEY in the container environment to require X-API-Key on all /upload, /download, and /files requests. If unset, endpoints are unprotected.

See docker-compose.yml for the placeholder.
