This project automates email-based user registration for LLM apps using the Model Context Protocol (MCP). It acts as a simple backend that receives email addresses from users, registers them with an MCP-compatible LLM server, and returns the generated API key or access token.

🚀 API Revolution: Model Context Protocol (MCP) Meets Web API
Welcome to MCP Server Tools! 🎯
This project exposes powerful APIs based on the Model Context Protocol (MCP) 🧩, representing a new revolution in API design 🌐 — structured, intelligent, and seamlessly extensible.
---
📚 Overview
- 🛠️ Combines Model Context Protocol (MCP) with traditional API endpoints to offer next-generation API experiences.
- 🔥 Redefines API architecture by enabling model-based communication, not just rigid HTTP contracts.
- 🧠 Applies Domain-Driven Design (DDD) at the core: aggregates, entities, and use cases are clearly separated and modeled around business logic.
- 🔐 Secures workflows like registration, login, and password change using industry best practices.
- 🧪 Extensible and modular — new tools can be added easily without modifying the core.
- 📈 Built with professional engineering principles: structured logging (via Serilog), robust error handling, clean separation of concerns.

🧩 Architecture Flow
Client ➡️ API Endpoint (ASP.NET Core) ➡️ MCP Client ➡️ MCP Server ➡️ Response
✅ You send a request to our API,
✅ We internally call the MCP Client,
✅ MCP Client talks to MCP Server,
✅ We return the clean final response to the API caller.
In short: You just send simple prompts, we handle everything behind the scenes. 🎩✨

🔥 Example Usage
📬 Register a New User
POST to:
https://localhost:7190/api/Prompt/SendUserPrompt/SendUserPrompt
Request body:
{
"Prompt": "hei dawg! my email: jackcorp@test666.com please help me to register"
}
Response:
Great! An email with your login details should be on its way.
Check your inbox for an email from us, containing your email address and password.
Remember to change your password after your first login for added security.
If you don't receive the email, please let me know and we'll try again.

🔒 Login and Change Password
POST to:
https://localhost:7190/api/Prompt/SendUserPrompt/SendUserPrompt
Request body:
{
"Prompt": "Bro Server! now please login me email: jackcorp@test666.com and password: d8X9sF & change the password with 123456"
}
Response:
Sure, I'll help you with that.
Now that you're logged in, I'll help you change your password to '123456'.
Your password has been successfully changed. If you have any other requests, feel free to let me know!
