Banking MCP Server (MongoDB Backend)
A simple Model Context Protocol (MCP) server for basic banking operations (CRUD) using MongoDB as the backend. This project demonstrates how to build an MCP server for account management and money transfers. This readme really needs some lovin. Not everything is documented.
Features

- Deposit, withdraw, and transfer funds
- Persistent storage with MongoDB
Prerequisites
- Python 3.8+
- MongoDB (local or cloud)
- uv (recommended)

- Clone the repository
git clone <repository-url>
cd banking-mcp-server-mdb- Install dependencies
uv pip install -r requirements.txt- Configure MongoDB
Create a .env file in the project root: ``env MONGO_URI=mongodb://localhost:27017 MONGO_DB=money_transfer_db `` Start your MongoDB server if not already running.
- Start the MCP server (Note: This doesn't do anything by itself. It's meant to be called via MCP Clients or toold like ClaudeDesktop)
./start_banking_mcp_server_mdb.sh- If running the temporal version for durable MCP, start the temporal worker
python -m mcp_server.workerClaude Desktop Configuration
