🚀 Installation

1. Clone the repository:

git clone https://github.com/yourusername/medicines-db.git
cd medicines-db

2. Install dependencies:

pip install -r requirements.txt

3. Prepare your medicine database:

# Ensure your JSON data file is at the correct path
# Default path: /Users/siddharthbajpai/Downloads/MCP_SERVER/medicines.json
# Update DATA_PATH in the code if needed

4. Run the server:

python medicines_server.py

📘 Usage

The server exposes multiple API endpoints through MCP (Model Context Protocol) architecture. You can interact with the server using any MCP client.

Basic example:

from mcp.client import MCPClient

# Connect to the server
client = MCPClient("medicines-db")

# Search for a medicine
result = client.search_medicines("paracetamol", max_results=5)
print(result)

# Get alternatives to a specific medicine
alternatives = client.suggest_alternatives("Dolo 650")
print(alternatives)

📚 API Reference

The server provides 15 API endpoints through the MCP framework:

📊 Data Structure

The system expects a JSON array of medicine objects with the following structure:

[
  {
    "Name": "Medicine Name",
    "Manufacturer": "Company Name",
    "Composition": "Ingredient1 (10mg) + Ingredient2 (20mg)",
    "MRP": "123.45",
    "Prescription": "Yes"
  },
  ...
]

The system enhances this data with additional computed fields:

• Price_INR: Formatted price with currency symbol
• Price_Category: Classification into Low/Medium/High/Premium
• Active_Ingredients: Extracted list of ingredients
• Ingredient_Count: Number of active ingredients
• Is_Combination: Whether the medicine contains multiple ingredients
• Requires_Prescription: Boolean for prescription requirement
• Prescription_Type: Human-readable prescription status

⚡ Performance Optimizations

The server implements several optimizations:

1. Multiple indices for fast lookups:

   • Name index
   • Manufacturer index
   • Composition index
   • Price index
   • Prescription index

2. Ingredient extraction is done once at startup to avoid repeated parsing

3. Similarity calculations use efficient algorithms:

   • SequenceMatcher for string similarity
   • Jaccard index for ingredient similarity

4. Price bucketing for faster range queries
