actual-mcp

MCP server for integrating Actual Budget with Claude and other LLM assistants.

The Actual Budget MCP Server allows you to interact with your personal financial data from Actual Budget using natural language through LLMs. It exposes your accounts, transactions, and financial metrics through the Model Context Protocol (MCP).

• Account Listings - Browse all your accounts with their balances
• Account Details - View detailed information about specific accounts
• Transaction History - Access transaction data with complete details

• get-transactions - Retrieve and filter transactions by account, date, amount, category, or payee
• spending-by-category - Generate spending breakdowns categorized by type
• monthly-summary - Get monthly income, expenses, and savings metrics
• balance-history - View account balance changes over time

• financial-insights - Generate insights and recommendations based on your financial data
• budget-review - Analyze your budget compliance and suggest adjustments

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

1. Clone the repository:

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

2. Install dependencies:

npm install

3. Build the server:

npm run build

4. 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"

To use this server with Claude Desktop, add it to your Claude configuration:

On MacOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

On Windows:

code %APPDATA%\Claude\claude_desktop_config.json

Add the following to your configuration:

{
  "mcpServers": {
    "actualBudget": {
      "command": "node",
      "args": ["/absolute/path/to/actual-budget-mcp/build/index.js"],
      "env": {
        "ACTUAL_DATA_DIR": "/path/to/your/actual/data"
      }
    }
  }
}

After saving the configuration, restart Claude Desktop.

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"

For development with auto-rebuild:

npm run watch

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

node build/index.js --test-resources

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

npx @modelcontextprotocol/inspector node build/index.js

• index.ts - Main server implementation
• types.ts - Type definitions for API responses and parameters
• prompts.ts - Prompt templates for LLM interactions
• utils.ts - Helper functions for date formatting and more
