# Finance MCP Server

A Model Control Protocol (MCP) server implementation for financial transaction management.

## Current Implementation

The server currently provides a basic REST API for managing financial transactions with the following features:

- FastAPI-based REST API
- In-memory transaction storage
- Basic CRUD operations for transactions
- Data validation using Pydantic models
- Auto-generated API documentation (Swagger UI)

### Project Structure

```
mcp/
├── mcp_server.py      # Main server implementation
├── requirements.txt   # Python dependencies
└── start_server.sh   # Server startup script
```

## Setup Instructions

1. Install Python dependencies:
   ```bash
   pip install -r requirements.txt
   ```

2. Make the start script executable:
   ```bash
   chmod +x start_server.sh
   ```

3. Start the server:
   ```bash
   ./start_server.sh
   ```

The server will start on `http://localhost:8000` with the following endpoints:
- `/` - Health check endpoint
- `/docs` - Auto-generated API documentation (Swagger UI)
- `/transactions` - Transaction management endpoints
  - GET /transactions - List all transactions
  - POST /transactions - Create a new transaction
  - GET /transactions/{id} - Get a specific transaction

## API Usage

### Create a Transaction
```bash
curl -X POST "http://localhost:8000/transactions" \
     -H "Content-Type: application/json" \
     -d '{
           "amount": 100.00,
           "description": "Grocery shopping",
           "category": "expenses"
         }'
```

### List All Transactions
```bash
curl "http://localhost:8000/transactions"
```
