🧠 MCP Server Function Routing

The MCP Server intelligently assigns functions based on the user's request.

Request Type	Assigned Function
Confidential data	Ollama
General AI questions	Groq
OCR request	OCR Router
Document Question Answering	ColBERT RAG
Internal Knowledge Search	ColBERT RAG
Image Text Extraction	EasyOCR / PaddleOCR / Tesseract

---

🤖 Ollama (Local AI)

Used for:

• Confidential company documents
• Internal business information
• Private knowledge bases
• Offline inference
• Sensitive AI workloads

Why Local?

Sensitive information should never leave the local environment.

Running Ollama locally ensures:

• Data privacy
• No cloud dependency
• Secure inference
• Low-latency responses

---

⚡ Groq API

Used for:

• Public knowledge
• General AI questions
• Coding assistance
• Summarization
• Non-confidential requests

Benefits

• Extremely fast inference
• Reduces local GPU usage
• Handles public AI workloads efficiently
• Improves overall response time

---

📚 Retrieval-Augmented Generation (RAG)

The platform uses pretrained ColBERT for semantic document retrieval.

Unlike traditional embedding-only retrieval, ColBERT performs late interaction retrieval, delivering higher search accuracy while maintaining excellent retrieval speed.

🚀 Why ColBERT?

The project uses a pretrained ColBERT model because it provides:

• Better semantic retrieval
• Higher search accuracy
• Context-aware ranking
• Reduced hallucinations
• Fast document search

---

🎮 GPU Usage for ColBERT

ColBERT uses the GPU for:

• Document indexing
• Embedding generation
• Semantic retrieval
• Similarity computation

Since ColBERT also consumes GPU memory, GPU resources are shared intelligently with other AI services.

The MCP Server manages these workloads to avoid GPU bottlenecks.

---

🎮 GPU Resource Management

The platform is optimized for an NVIDIA GTX 1650 (4 GB VRAM).

Since multiple services may require GPU acceleration, the MCP Server prioritizes workloads dynamically.

GPU Consumers

Service	GPU Usage
Ollama	High
ColBERT Retrieval	Medium
EasyOCR	Medium
PaddleOCR	Medium
Groq	None (Cloud)
Tesseract	CPU Only

---

GPU Priority

Priority order:

1. Ollama
2. ColBERT Retrieval
3. EasyOCR
4. PaddleOCR
5. Tesseract (CPU)
6. Groq (Cloud)

This scheduling minimizes GPU contention while maintaining responsive performance.

---

📄 Intelligent OCR Pipeline

The OCR engine is selected automatically depending on GPU availability.

High Performance Mode

When GPU resources are available:

• EasyOCR
• PaddleOCR

Advantages:

• High accuracy
• Better multilingual support
• Faster extraction
• Handles scanned documents effectively

---

Lightweight Mode

When Ollama or ColBERT is actively using the GPU:

• Tesseract OCR

Advantages:

• CPU-based
• Lightweight
• Fast startup
• Prevents long response delays

This ensures users are not waiting unnecessarily while GPU-intensive services are running.
