🧠 MCP Server (Model Compute Paradigm)

A modular, production-ready FastAPI server built to route and orchestrate multiple AI/LLM-powered models behind a unified, scalable interface. It supports streaming chat, LLM-based routing, and multi-model pipelines (like analyze → summarize → recommend) – all asynchronously and fully Dockerized.

🎯 Project Score (Production Readiness)

Capability	Status	Details
🧠 Multi-Model Orchestration	✅ Complete	Dynamic routing between `chat`, `summarize`, `sentiment`, `recommend`
🤖 LLM-Based Task Router	✅ Complete	GPT-powered routing via `"auto"` task type
🔁 Async FastAPI + Concurrency	✅ Complete	Async/await + concurrent task execution with simulated/model API delays
🔊 GPT Streaming Support	✅ Complete	`text/event-stream` chunked responses for chat endpoints
🧪 Unit + Mocked API Tests	✅ Complete	Pytest-based test suite with mocked `run()` responses
🐳 Dockerized + Clean Layout	✅ Complete	Python 3.13 base image, no Conda dependency, production-ready Dockerfile
📦 Metadata-Driven Registry	✅ Complete	Model metadata loaded from external YAML config
🔐 Rate Limiting & Retry	⏳ In Progress	Handles 429 retry loop; rate limiting controls WIP
🧪 CI + Docs	⏳ Next	GitHub Actions + Swagger/Redoc planned

🧩 Why This Project? (Motivation)

Modern ML/LLM deployments often involve:

Multiple task types and model backends (OpenAI, HF, local, REST)
Routing decisions based on input intent
Combining outputs of multiple models (e.g., summarize + recommend)
Handling 429 retries, async concurrency, streaming responses

🔧 However, building such an LLM backend API server that is:

Async + concurrent
Streamable
Pluggable (via metadata)
Testable
Dockerized … is non-trivial and not easily found in one single place.

💡 What We’ve Built (Solution)

This repo is a production-ready PoC of an MCP (Model-Compute Paradigm) architecture:

✅ FastAPI-based microserver to handle multiple tasks via /task endpoint
✅ Task router that can:
- 🔁 Dispatch to specific model types (chat, sentiment, summarize, recommend)
- 🤖 Use an LLM to infer which task to run (auto)
- 🧠 Run multiple models in sequence (analyze)
✅ GPT streaming via text/event-stream
✅ Async/await enabled architecture for concurrency
✅ Clean modular code for easy extension
✅ Dockerized for deployment
✅ Tested using Pytest with mocking

🛠️ Use Cases

Use Case	MCP Server Support
Build your own ChatGPT-style API	✅ `chat` task with streaming
Build intelligent task router	✅ `auto` task with GPT-powered intent parsing
Build AI pipelines (like RAG/RL)	✅ `analyze` task with sequential execution
Swap between OpenAI/HuggingFace APIs	✅ Via `model_registry.yaml` config
Add custom models (e.g., OCR, vision)	✅ Just add a new module + registry entry

🚀 Features

✅ Async FastAPI server

📄 Model Registry from YAML/JSON
🔁 Automatic Retry and Rate Limit Handling for APIs
🔄 Streaming Responses for Chat
🧪 Unit Tests + Mocked API Calls
🐳 Dockerized for production deployment
📦 Modular structure, ready for CI/CD
