# MCP Authentication

> Connect your favorite AI assistant, such as Claude, ChatGPT, Cursor, or Perplexity, to the Aries trading platform using **MCP (Model Context Protocol)**.

## Add MCP Server to All Platforms

1. **Generate your MCP key (Client ID)** - Open [Client Center / Manage Account](https://app.aries.com/client-center), go to the **API** section, and click **Generate MCP Key**. Copy the key - this is your **Client ID**.

2. **Enter the Remote MCP server URL** - In your platform, add Aries as a custom connector / MCP server using this **exact** URL (no trailing slash):

   ```
   https://mcp.aries.com/mcp
   ```

3. **Enter your Client ID** - Paste the MCP key you copied in step 1.

4. **Sign in and allow access** - Your platform opens the Aries sign-in page. Sign in and click **Allow** to finish.

## Static Client ID (without Dynamic Client Registration)

Aries MCP doesn't support [Dynamic Client Registration (DCR)](https://modelcontextprotocol.io/specification/2025-06-18/basic/authorization#dynamic-client-registration). Instead, [create your own OAuth app](#create-an-oauth-app), copy its **Client ID**, and add it in your platform (often a config file like `mcp.json`). Your browser then opens to sign in and allow access.

<Warning>
  **In short, a Client ID is a must.**
</Warning>
