# Integrations & Tools

> Connect an AI assistant to DualEntry with MCP, or design, build, and certify a custom Public API integration for the partner program.

Beyond the CLI, DualEntry offers two other ways to build on your organization's data: an MCP server for AI assistants, and a partner program for custom Public API integrations.

## What this section covers

* **[DualEntry MCP: Developer Overview](./mcp)**: connect Claude, Cursor, and other MCP clients to your accounting data.
* **[How Custom Integrations Work](./how-custom-integrations-work)**: the architecture, integration categories, and complexity tiers behind a partner integration.
* **[How to Build a Custom DualEntry Integration](./how-to-build-a-custom-integration)**: the implementation steps, from partner access through error handling and multi-currency support.
* **[Custom Integration Reference](./custom-integration-reference)**: the certification checklist, common pitfalls, and troubleshooting reference the integrations team checks against.

## Where to go next

If you're scripting rather than building a hosted integration, the [Command-Line Interface](../cli/index) covers the same API without the partner program's certification requirements.
