# Overview

> Moralis Cortex is your gateway to real-time, AI-driven insights from blockchain data. Ask natural language questions. Get structured, explainable answers. Use it via our hosted API or run the Cortex MCP Server in your own infrastructure.

<Warning>
  **Deprecated — scheduled for removal on June 4, 2026.** The Cortex API is being retired. Migrate to [Onchain Skills](/data-api/onchain-skills/overview), which replaces Cortex with a more capable AI interface for Moralis data. See the [changelog](/changelog) for details.
</Warning>

## What is Moralis Cortex?

Moralis Cortex is an AI-native data layer for Web3, built on top of the Moralis Model Context Protocol (MCP). It connects blockchain data with large language models like GPT-4 or Claude - enabling you to query on-chain activity using plain English or structured prompts.

Whether you're building dashboards, bots, reports, or intelligent assistants, Cortex gives you the power of AI - grounded in real blockchain data.
