# Build with LLMs

## Before you start

Create an app in the [Developer Portal](https://developer.world.org). You will need the `app_id`, `rp_id` and the signing key for the integration.

Prefer to integrate manually? Follow the [IDKit integration guide](/world-id/idkit/integrate) for the complete client, signing, verification, and testing flow.

Copy this prompt and paste it into Codex, Claude, Cursor, or your preferred AI coding assistant:

```text title="Copy this prompt" theme={null}
Read world.id/SKILL.md and add World ID to my app
```

## World MCP

You can also connect your AI assistant to World with MCP servers:

* [World Docs MCP](/model-context-protocol/world-docs): search documentation while editing code.
* [Developer Portal MCP](/model-context-protocol/developer-portal): create apps, configure World ID, and manage Mini App setup from your MCP client.
