💡 What is this?
This is an MCP (Model Context Protocol) server that runs in Docker and gives AI assistants (like Claude, Cursor, or any MCP-compatible client) the ability to generate real Office files on demand.
Just ask your AI to "create a sales presentation" or "draft a welcome email" — and it will produce a ready-to-use file for you.
No coding required. Install, connect, and start creating.

Bonus — Dynamic Templates:
- 📧 Reusable Email Templates — Define parameterized email layouts in YAML. Each becomes its own tool with typed arguments (e.g.,
first_name,promo_code). - 📝 Reusable Word Templates — Create
.docxfiles with{{placeholders}}. Each template becomes an AI tool. Placeholders support full Markdown.
Output options:
- Local — Files saved to the
output/folder - Cloud — Upload to S3, Google Cloud Storage, Azure Blob, or MinIO and get a time-limited download link
🚀 Quick Start
Get up and running in 3 steps:
1. Download the compose file
curl -L -o docker-compose.yml https://raw.githubusercontent.com/dvejsada/mcp-ms-office-docs/main/docker-compose.yml
Already cloned the repo? Skip this step —
docker-compose.ymlis already there.
2. Set up your environment
cp .env.example .env
The defaults work out of the box — files will be saved locally to output/.
3. Start the server
docker-compose up -d
✅ Done! Your MCP endpoint is ready at: http://localhost:8958/mcp
⚙️ Configuration
The server is configured through environment variables in your .env file.
Basic Settings
| Variable | Description | Default |
|---|---|---|
DEBUG | Enable debug logging (1, true, yes) | (off) |
API_KEY | Protect the server with an API key (see Authentication below) | (disabled) |
UPLOAD_STRATEGY | Where to save files: LOCAL, S3, GCS, AZURE, MINIO | LOCAL |
SIGNED_URL_EXPIRES_IN | How long cloud download links stay valid (seconds) | 3600 |
🔐 Authentication
Set API_KEY in your .env to require an API key for all requests:
API_KEY=your-secret-key
Clients can send the key in any of these headers:
| Header | Format |
|---|---|
Authorization | Bearer your-secret-key |
Authorization | your-secret-key |
x-api-key | your-secret-key |
Leave API_KEY empty or unset to allow all requests without authentication.
☁️ AWS S3 Storage
Set UPLOAD_STRATEGY=S3 and provide:
| Variable | Description |
|---|---|
AWS_ACCESS_KEY | Your AWS access key |
AWS_SECRET_ACCESS_KEY | Your AWS secret key |
AWS_REGION | AWS region (e.g., us-east-1) |
S3_BUCKET | S3 bucket name |
☁️ Google Cloud Storage
Set UPLOAD_STRATEGY=GCS and provide:
| Variable | Description |
|---|---|
GCS_BUCKET | GCS bucket name |
GCS_CREDENTIALS_PATH | Path to service account JSON (default: /app/config/gcs-credentials.json) |
Mount the credentials file via docker-compose.yml volumes.
☁️ Azure Blob Storage
Set UPLOAD_STRATEGY=AZURE and provide:
| Variable | Description |
|---|---|
AZURE_STORAGE_ACCOUNT_NAME | Storage account name |
AZURE_STORAGE_ACCOUNT_KEY | Storage account key |
AZURE_CONTAINER | Blob container name |
AZURE_BLOB_ENDPOINT | (Optional) Custom endpoint for sovereign clouds |
☁️ MinIO / S3-Compatible Storage
Set UPLOAD_STRATEGY=MINIO and provide:
| Variable | Description | Default |
|---|---|---|
MINIO_ENDPOINT | MinIO server URL (e.g., https://minio.example.com) | (required) |
MINIO_ACCESS_KEY | Access key | (required) |
MINIO_SECRET_KEY | Secret key | (required) |
MINIO_BUCKET | Bucket name | (required) |
MINIO_REGION | Region | us-east-1 |
MINIO_VERIFY_SSL | Verify SSL certificates | true |
MINIO_PATH_STYLE | Use path-style URLs (recommended for MinIO) | true |
Make sure the bucket exists and your credentials have PutObject/GetObject permissions.
🎨 Custom Templates
You can customize the look of generated documents by providing your own templates.
Static Templates
Place files in the custom_templates/ folder:
| Document | Filename | Notes |
|---|---|---|
| PowerPoint 4:3 | custom_pptx_template_4_3.pptx | |
| PowerPoint 16:9 | custom_pptx_template_16_9.pptx | |
| Word | custom_docx_template.docx | |
| Email wrapper | custom_email_template.html | Base it on default_templates/default_email_template.html |
Dynamic Email Templates
Create reusable, parameterized email layouts that your AI can fill in automatically.
📧 How to set up dynamic email templates
1. Create config/email_templates.yaml:
templates:
- name: welcome_email
description: Welcome email with optional promo code
html_path: welcome_email.html # must be in custom_templates/ or default_templates/
annotations:
title: Welcome Email
args:
- name: first_name
type: string
description: Recipient's first name
required: true
- name: promo_code
type: string
description: Optional promotional code (HTML formatted)
required: false
2. Create the HTML file in custom_templates/welcome_email.html:
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8" /></head>
<body>
<h2>Welcome {{first_name}}!</h2>
<p>We're excited to have you on board.</p>
{{{promo_code_block}}}
<p>Regards,<br/>Support Team</p>
</body>
</html>
How it works:
- Each template becomes a separate AI tool at startup
- Standard email fields (subject, to, cc, bcc, priority, language) are added automatically
- Use
{{variable}}for escaped text,{{{variable}}}for raw HTML
Dynamic Word (DOCX) Templates
Create reusable Word documents with {{placeholders}} that support full Markdown formatting.
📝 How to set up dynamic DOCX templates
1. Create config/docx_templates.yaml:
templates:
- name: formal_letter
description: Generate a formal business letter
docx_path: letter_template.docx # must be in custom_templates/ or default_templates/
annotations:
title: Formal Letter Generator
args:
- name: recipient_name
type: string
description: Full name of the recipient
required: true
- name: recipient_address
type: string
description: Recipient's address
required: true
- name: subject
type: string
description: Letter subject
required: true
- name: body
type: string
description: Main body of the letter (supports markdown)
required: true
- name: sender_name
type: string
description: Sender's name
required: true
- name: date
type: string
description: Letter date
required: false
default: ""
2. Create a Word document with placeholders and save as custom_templates/letter_template.docx:
{{date}}
{{recipient_name}}
{{recipient_address}}
Subject: {{subject}}
{{body}}
{{sender_name}}
How it works:
- Each template becomes a separate AI tool at startup
- Placeholders can be in the document body, tables, headers, and footers
- Placeholder values support full Markdown (bold, italic, lists, headings…)
- The original font from the placeholder location is preserved
🎯 Word style requirements for custom templates
For proper formatting, make sure these styles exist in your .docx template:
| Category | Styles |
|---|---|
| Headings | Heading 1 – Heading 6 |
| Bullet lists | List Bullet, List Bullet 2, List Bullet 3 |
| Numbered lists | List Number, List Number 2, List Number 3 |
| Other | Normal, Quote, Table Grid |
Tip: Customize these styles (font, size, color, spacing) in your template — the server will use your styling.
🔌 Connecting Your AI Client
Point your MCP-compatible client to the server endpoint:
http://localhost:8958/mcp
Examples for popular clients:
Claude Desktop
Add to your Claude Desktop MCP config:
{
"mcpServers": {
"office-documents": {
"url": "http://localhost:8958/mcp"
}
}
}
LibreChat
Add the server to your librechat.yaml configuration under mcpServers:
mcpServers:
office-documents:
type: streamableHttp
url: http://mcp-office-docs:8958/mcp
Note: If LibreChat and this server run in the same Docker network, use the container name (
mcp-office-docs) as the hostname. If they run separately, usehttp://localhost:8958/mcpinstead.
To place both services on the same network, add a shared network in your docker-compose.yml:
services:
mcp-office-docs:
# ...existing config...
networks:
- shared
librechat:
# ...existing config...
networks:
- shared
networks:
shared:
driver: bridge
Cursor / Other MCP Clients
Use the SSE/streamable HTTP transport and set the endpoint URL to:
http://localhost:8958/mcp
If you have authentication enabled, add the API key header as required by your client.
