🚀 Memory Data Server (MCP Tool Provider)

A lightweight Model Context Protocol (MCP) server built with Python and FastMCP. This service acts as a specialized tool provider that enables LLMs and Agentic AI systems (like LangChain or Claude Desktop) to securely inspect and retrieve customer support records from an in-memory datastore via Server-Sent Events (SSE).

📌 Features

• Standardized MCP Interface: Exposes backend capabilities via the open Model Context Protocol.

• SSE Transport: Listens on HTTP via Server-Sent Events for real-time remote procedure calls (RPC).

• Structured Tool Capabilities: Exposes deterministic data querying functions (fetch_customer_ticket) with typed parameters.

🛠 Tech Stack

• Language: Python 3.10+

• Framework: mcp (FastMCP)

• Transport: SSE (Server-Sent Events) over HTTP

🚀 Getting Started

1. Prerequisites

Ensure you have Python installed and the required dependencies:

pip install mcp

2.Running the Server

Execute the script directly to start the FastMCP SSE server listening on 0.0.0.0:8000:

python server.py

The server will start and wait for incoming SSE connections on port 8000.

🛠 Available Tools fetch_customer_ticket Performs an in-memory lookup for customer support tickets using a numeric ticket_id.

Parameters:

ticket_id (int, required): The unique integer identifier of the target ticket.

Returns:

str: Formatted string containing user details, reported issue, and customer tier (or a formatted error message if not found).
