GenFiles MCP Server 🧩

GenFiles is an MCP Server that generates PowerPoint, Excel, Word, or Markdown files from user requests and chat context. This server executes Python templates or structured document builders to produce files, uploads them to an Open Web UI (OWUI) endpoint, and can persist them in Open WebUI knowledge collections depending on the selected transport and configuration. Additionally, it supports analyzing and reviewing existing Word documents by extracting their structure and adding comments for corrections, grammar suggestions, or idea enhancements.

Quick Start (MCP HTTP Streamable) Installation Guide.

Installation

To quickly get started, you can use the pre-built Docker image:

docker pull ghcr.io/baronco/genfilesmcp:v0.3.0

Run the container:

docker run -d --restart unless-stopped -p 8016:8016 \
  -e OWUI_URL="http://host.docker.internal:3000" \
  -e PORT=8016 \
  -e REVIEWER_AI_ASSISTANT_NAME="GenFilesMCP" \
  -e ENABLE_CREATE_KNOWLEDGE=false \
  --name gen_files_mcp \
  ghcr.io/baronco/genfilesmcp:v0.3.0

Or copy and paste this one-liner:

docker run -d --restart unless-stopped -p 8016:8016 -e OWUI_URL="http://host.docker.internal:3000" -e PORT=8016 -e REVIEWER_AI_ASSISTANT_NAME="GenFilesMCP" -e ENABLE_CREATE_KNOWLEDGE=false --name gen_files_mcp ghcr.io/baronco/genfilesmcp:v0.3.0

Environment Variables

Variable	Description	Example
OWUI_URL	URL of your Open Web UI instance	http://host.docker.internal:3000
PORT	Port where the MCP Server will listen	8016
MCP_TRANSPORT	MCP transport used at startup. Use streamable-http for direct HTTP deployments such as Open WebUI external tools, or stdio when the server is launched by MCPO or another stdio-capable MCP client.	streamable-http
OWUI_API_KEY	API key used only for stdio deployments through MCPO, where Open WebUI cannot forward the active user's bearer token through the Open WebUI -> MCPO -> stdio MCP chain. Do not use it for direct streamable-http deployments.	sk-017374a....
KNOWLEDGE_COLLECTION_NAME	Name of the Open WebUI knowledge collection used for generated and reviewed files when ENABLE_CREATE_KNOWLEDGE=true.	My Generated Files
REVIEWER_AI_ASSISTANT_NAME	Author name used inside Word comments created by review_docx.	GenFilesMCP
ENABLE_CREATE_KNOWLEDGE	Controls whether generated or reviewed files are attached to Open WebUI knowledge collections. In direct streamable-http mode this is optional. In stdio through MCPO it must be true.	false
ENABLE_WORD_ELEMENT_FILLING	Experimental DOCX mode. false keeps the code-generation flow; true switches to the structured element-based builder.	false

For more detailed installation instructions, see the Installation Guide.

What Can It Do?

• Generate files in multiple formats (PowerPoint, Excel, Word, Markdown).
• Review Word documents with AI-generated comments for grammar and idea enhancements.
• Integrate seamlessly with Open Web UI for file uploads and knowledge management.

Examples of Generated Files 📄

DOCX Files 📝

• Code-based generation: The LLM writes Python code to generate the document.
• Template-based generation: The LLM defines the structure, and the backend builds the document (best results with Claude Haiku 4.5 and Kimi K2.5, 5.0/5).

• Reviewer Mode: Add comments for grammar and idea enhancements.

PPTX Files 📊

The latest GPT models can generate PowerPoint files with good structure and formatting. You can try gpt-5.2 or gpt-5.4 for best style and formatting results.

XLSX Files 📈

The server can generate Excel files with multiple sheets, tables, and charts. The quality of formatting and structure depends on the model used, with the latest GPT models producing the best results.
