Phantom Connect SDK — Cursor Plugin

AI-powered assistance for integrating the Phantom Connect SDK into your Solana and EVM applications. This Cursor plugin provides skills, rules, an agent, and a live MCP server so Cursor can scaffold projects, write correct integration code, and search Phantom docs in real-time.

Installation

1. Clone or copy this plugin into your Cursor plugins directory, or open the folder in Cursor.
2. Cursor will automatically detect the .cursor-plugin/plugin.json manifest.
