Usage with Claude Desktop

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.

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

Releases

Releases are automated using Changesets and GitHub Actions. On every push to main, a release PR is created and, once merged, a new version is published to npm and a Docker image is built and pushed to GitHub Container Registry.

• To create a release, add a changeset with npx changeset and merge to main.
• The release workflow will handle npm publishing and Docker image publishing automatically.
