Question 1

What is an MCP Server?

Accepted Answer

An MCP (Model Context Protocol) Server acts as a bridge, allowing AI models to access and interact with external data sources and tools. It standardizes how applications provide context to Large Language Models (LLMs), enabling more informed decision-making and automation.

Question 2

What are the key components of the MCP Server?

Accepted Answer

The MCP Server includes n8n (automation platform), Ollama (local LLM platform), Qdrant (vector store), Prometheus (monitoring), Grafana (visualization), Whisper (speech-to-text), Caddy (HTTPS/TLS), Supabase (database & auth), Flowise (AI agent builder), Open WebUI (ChatGPT-like interface), and SearXNG (privacy-focused search engine).

Question 3

What are the minimum system requirements for running the MCP Server?

Accepted Answer

You need an Ubuntu VPS (tested on 22.04 LTS), a domain name with DNS access, a minimum of 16GB RAM, 100GB+ storage, and Docker/Docker Compose installed.

Question 4

How do I install the MCP Server?

Accepted Answer

Connect to your VPS via SSH, install the required packages, configure the firewall, clone the repository, run the configuration script, and use the `start_services.py` script to start the AI stack.

Question 5

How do I access the different services after installation?

Accepted Answer

You can access the services via the provided URLs, such as `https://n8n.kwintes.cloud` for n8n, `https://openwebui.kwintes.cloud` for the Web UI, and so on.

Question 6

How do I update the MCP Server to the latest version?

Accepted Answer

Use the provided `update_stack.sh` script to pull the latest Docker images, apply configuration fixes, and restart all services.

Question 7

How do I back up the MCP Server data?

Accepted Answer

Use the `backup_stack.sh` script to back up all Docker volumes, configuration files, and secrets to a timestamped archive.

Question 8

What if I encounter Docker Compose issues during installation?

Accepted Answer

The script automatically detects and uses the correct Docker Compose command format for your system. If you're manually running commands, use `docker compose` or `docker-compose` depending on your setup. If issues persist, install the standalone Docker Compose binary.

Question 9

How does the MCP Server ensure data privacy and security?

Accepted Answer

All AI models run locally on your VPS, preventing data from being sent to external services. Automatic HTTPS/TLS encryption, firewall rules, and secure secret management provide additional layers of security.

Question 10

How can I integrate the MCP Server with the UBOS Platform?

Accepted Answer

Use the UBOS Platform to orchestrate AI Agents running on your MCP Server, connect them to enterprise data, build custom AI Agents, and create sophisticated Multi-Agent Systems.

Question 11

What models are installed automatically?

Accepted Answer

Several models are automatically installed, including language models like `gemma3:12b`, `granite3-guardian:8b`, `llama3.2-vision`, and embedding models like `granite-embedding:278m` and `nomic-embed-text:latest`. These models are downloaded during the initial setup.

Question 12

How do I monitor the health and performance of my MCP Server?

Accepted Answer

Access Grafana to view dashboards or Prometheus to directly check the targets and create alerts. These tools provide detailed insights into service health and performance metrics.
