Cursor is an AI-first code editor with a built-in chat and agent mode. The setup below gets live CoinGecko data and correct SDK patterns into every session.

​
1. Add the MCP Server

Cursor supports MCP natively. Open Settings → MCP → Add new MCP server and paste the config below, or edit ~/.cursor/mcp.json directly. 
{
  "mcpServers": {
    "coingecko_mcp": {
      "command": "npx",
      "args": ["mcp-remote", "https://mcp.api.coingecko.com/mcp"]
    }
  }
}
After saving, restart Cursor. You’ll see coingecko_mcp under Available Tools in the chat sidebar. Full instructions: MCP Server docs.

​
2. Add AI prompt rules

Cursor lets you project-scope rules via .cursor/rules/*.mdc (or the legacy .cursorrules file). Paste our SDK prompt into a rule file so every generation follows the right patterns.
Name the rule file something like coingecko-sdk.mdc and set alwaysApply: true in the frontmatter so it’s loaded on every request.

​
What to try next

Try prompting Cursor’s agent mode with:
“Using the CoinGecko MCP tool, fetch the current BTC and ETH prices and build a React widget that displays them with live updates.”
“Write a TypeScript script that pulls the top 50 coins by market cap and exports them to a CSV.”
