Installation

Prerequisites

• Node.js (v16 or higher)
• Actual Budget installed and configured
• Claude Desktop or another MCP-compatible client

Setup

1. Clone the repository:

git clone https://github.com/s-stefanov/actual-mcp.git
cd actual-mcp

1. Install dependencies:

npm install

1. Build the server:

npm run build

1. Configure environment variables (optional):

# Path to your Actual Budget data directory (default: ~/.actual)
export ACTUAL_DATA_DIR="/path/to/your/actual/data"

# If using a remote Actual server
export ACTUAL_SERVER_URL="https://your-actual-server.com"
export ACTUAL_PASSWORD="your-password"

# Specific budget to use (optional)
export ACTUAL_BUDGET_SYNC_ID="your-budget-id"

Example Queries

Once connected, you can ask Claude questions like:

• "What's my current account balance?"
• "Show me my spending by category last month"
• "How much did I spend on groceries in January?"
• "What's my savings rate over the past 3 months?"
• "Analyze my budget and suggest areas to improve"

Development

For development with auto-rebuild:

npm run watch

Testing the connection to Actual

To verify the server can connect to your Actual Budget data:

node build/index.js --test-resources

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. You can use the MCP Inspector:

npx @modelcontextprotocol/inspector node build/index.js

Project Structure

• index.ts - Main server implementation
