Prerequisites

• Ledger CLI
  must be installed and available in your PATH
• A valid Ledger file with your financial data

Installation

Using uv (recommended)

The easiest way to install and run this server is with uv
:

uv sync

Configuration

The server requires a path to your Ledger file. This can be provided through:

• The LEDGER_FILE environment variable
• Command-line arguments when starting the server

Using with Claude Desktop

Add this to your claude_desktop_config.json:

"mcpServers": {
  "ledger": {
    "command": "uv",
    "args": [\
      "run",\
      "--env-file",\
      "/path/to/your/.env",  // Optional: to set LEDGER_FILE\
      "--with",\
      "mcp[cli]",\
      "mcp",\
      "run",\
      "<repo_path>/main.py"  // Path to the main.py file in this repository\
    ]
  }

}

Usage Examples

Once configured, you can ask your AI assistant questions about your financial data:

• "Show me my expenses for the last month"
• "What's my current balance in all accounts?"
• "List all transactions with Amazon"
• "How much did I spend on groceries in 2023?"
• "Show me my budget performance for Q1"

The AI will use the appropriate Ledger CLI commands through the server to get the information.

Debugging

For more detailed local testing:

mcp dev main.py

Development
