MCP for Cursor

1. Overview​

MCP (Model Context Protocol) is a protocol that enables AI applications to connect to external AI services through API systems. This guide covers configuring MCP to connect to Creative AI models, allowing you to access flexible AI capabilities within applications like Cursor Desktop, Claude Desktop, and other compatible tools.

How It Works​

MCP acts as a bridge between your AI application and the Creative AI API:

  1. You send a query through your application's interface
  2. MCP forwards the request to the Creative AI API endpoint
  3. The Creative AI API processes your request and returns the response
  4. You see the result in your application's interface

Prerequisites​

2. Configuration Setup​

Step 1: Edit the configuration file​

Option 1: Through Install Link (Recommended)

  1. Click into this URL
  2. Insert YOUR_ETERNAL_AI_API_KEY and complete the installation

Option 2: Through Cursor Settings

  1. Open Cursor Settings
    • Click the gear icon (⚙️) in the top right corner
  2. Navigate to Tools & MCP section in the left sidebar
  3. Under "Installed MCP Servers", you'll see your existing servers
  4. Click the "+ New MCP Server" button at the bottom
    • This will open the configuration interface to add a new MCP server
  5. Add the following configuration to the mcpServers field:

{
  "eternal-ai": {
    "type": "sse",
    "url": "https://smart-agent-api.eternalai.org/mcp/sse",
    "headers": {
      "Authorization": "Bearer <YOUR_ETERNAL_AI_API_KEY>"
    }
  }
}

The complete configuration file will look like this:


{
  "mcpServers": {
   ...,
    "eternal-ai": {
      "type": "sse",
      "url": "https://smart-agent-api.eternalai.org/mcp/sse",
      "headers": {
        "Authorization": "Bearer sa_9022..."
      }
    }
  }
}

Step 2: Save and Restart​

  1. Save the configuration file
  2. Restart Cursor Desktop completely for changes to take effect
  3. In the Tools & MCP section, you should see the "eternal-ai" server with a green indicator (●) and "... tools enabled" message in the Installed MCP Servers list, confirming successful installation.

3. Usage Guide​

Starting a Conversation with MCP​

Once configured, MCP tools are automatically available when you chat in Cursor.

  1. Open Cursor Desktop
  2. Open the chat panel (usually on the right side or via Command Palette)
  3. Start asking questions that involve your configured resources
