Expense Tracker MCP Proxy for Remote Server

A Model Context Protocol (MCP) proxy server that connects to a remote expense tracker FastMCP cloud server and exposes its tools locally.

Note: This is a proxy server only. It connects to a remote FastMCP cloud URL and forwards requests to the actual expense tracking implementation. The source code for the expense tracking functionality is available at: expense-tracker-remote-mcp-server

Features

This proxy server:

Connects to the remote FastMCP server at https://chronic-scarlet-urial.fastmcp.app/mcp
Automatically discovers and exposes all tools available on the remote server
Forwards all tool calls to the remote server
Provides transparent proxying with error handling
Handles Server-Sent Events (SSE) responses from the FastMCP server
Acts as a local stdio interface to the remote expense tracker implementation

Remote Server Tools

The remote FastMCP server provides an Expense Tracker with 5 tools:

add_expense: Add a new expense with date, amount, category, subcategory, and notes
list_expenses: List expenses with optional filtering by category and date range
update_expense: Update an existing expense
delete_expense: Delete an expense
summarize_expenses: Get expense summaries grouped by category

Installation

Install dependencies:

pip install -e .

Or install manually:

pip install mcp aiohttp

Usage

Run the server:

python main.py

The server communicates via stdio and follows the Model Context Protocol specification.

Configuration

To use this server with an MCP client (like Claude Desktop), add it to your client configuration:

{
  "mcpServers": {
    "bhakti-server-proxy": {
      "command": "python",
      "args": ["d:\\Python Projects\\Proxy-server\\main.py"]
    }
  }
}

Or with the full Python path:

{
  "mcpServers": {
    "bhakti-server-proxy": {
      "command": "C:\\Users\\kulsu\\AppData\\Local\\Programs\\Python\\Python314\\python.exe",
      "args": ["d:\\Python Projects\\Proxy-server\\main.py"]
    }
  }
}

Development

The server is built using the mcp Python library and implements:

Tool listing from remote server
Tool execution forwarding to remote server
Async stdio communication
Server-Sent Events (SSE) handling

Testing

Test the connection to the remote server:

python test_proxy.py
