DualEntry gives you three ways to build on your organization’s accounting data: a RESTful Public API, a command-line interface, and an MCP server for AI assistants. Pick the surface that fits what you’re building, or jump straight into a quickstart below.

​
Key sections

Public API

Authenticate, then work through Core Concepts (versioning, rate limits, pagination, errors) and Building Blocks (attachments, bank feeds, tax) to call any resource.

API Reference

Every endpoint, request and response schema, and parameter.

Command-Line Interface

Install the CLI, look up every command and flag, and copy-paste task recipes for invoice review, close, and CI/CD.

DualEntry MCP

Connect Claude, Cursor, VS Code, and other MCP clients to your accounting data.
