# Introduction

> Cactal is the agent-native website platform. Build with the built-in Cactal agent, or create, edit, publish, and operate production websites through the dashboard, the REST API, or MCP.

Cactal is the agent-native website platform. The built-in [Cactal agent](/docs/agents/cactal-agent) builds and operates websites from a conversation beside the live preview, and everything it can do you can also do yourself or hand to an agent of your own.

Every capability is available three ways: the [dashboard](https://app.cactal.ai), the [REST API](/docs/api-reference/introduction), and the [MCP server](/docs/agents/mcp). All three run the same operations with the same permissions, rate limits, and audit trail. There is no private API.

## Build with agents

Cactal treats AI agents as first-class operators. The built-in Cactal agent works on every site with no setup, and you can also bring your own: connect an agent over MCP, scope its key to exactly the sites it manages, review its drafts before they go live, and audit everything it does.
