# Phantom Cursor plugin
> Give your AI coding agent wallet capabilities, SDK knowledge, and Phantom best practices directly in Cursor
The [Phantom Cursor plugin](https://cursor.com/marketplace/phantom) gives your AI coding agent everything it needs to build with Phantom. It bundles MCP servers, subagents, skills, and rules into a single install so Cursor can scaffold projects, write integration code, execute wallet operations, and follow Phantom best practices automatically.
The plugin is available on the [Cursor Marketplace](https://cursor.com/marketplace/phantom). Install it directly from Cursor or visit the marketplace page.
## Install
Add the plugin to Cursor using the command palette or the marketplace:
Press `Cmd + Shift + P` (Mac) or `Ctrl + Shift + P` (Windows/Linux) and search for **"Add Plugin"**.
Type `phantom-connect` and select **Phantom Connect** from the results.
Cursor will add the plugin. You may need to restart Cursor for all features to activate.
You can also install by visiting [cursor.com/marketplace/phantom](https://cursor.com/marketplace/phantom) and selecting **Add to Cursor**.
## What's included
The plugin bundles four categories of capabilities into one install.
### Subagents
Specialized AI agents that Cursor can delegate tasks to:
| Subagent | Description |
| -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `phantom-integration-specialist` | Scaffolds projects, writes correct integration code, validates against SDK constraints, and searches Phantom docs in real time |
| `phantom-wallet-agent` | Executes wallet operations: address and balance reads across Solana, EVM, Bitcoin, and Sui; transfers, swaps, simulation, and signing on Solana and EVM; ERC-20 allowance checks on EVM; portfolio rebalancing on Solana; Hyperliquid perps; and CASH API payments |
### Skills
Step-by-step workflows the agent follows to complete common tasks:
| Skill | Description |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `setup-react-app` | Scaffold a React app with Phantom Connect SDK, including social login and Solana support |
| `setup-react-native-app` | Scaffold a React Native (Expo) app with Phantom React Native SDK, including polyfills and deep linking |
| `setup-browser-app` | Scaffold a vanilla JS/TS app with Phantom Browser SDK, without any framework dependency |
| `add-social-login` | Configure Google and Apple social login with Phantom Connect SDK to enable embedded wallet creation |
| `send-sol-transaction` | Build and send SOL transfers with Phantom Connect SDK, including transaction construction, signing, and verification |
| `sign-message` | Implement message signing with Phantom Connect SDK for Solana and EVM, including Sign-in with Solana (SIWS) authentication |
| `phantom-wallet-mcp` | Execute wallet operations through the Phantom MCP server: multi-chain address and balance reads (Solana, EVM, Bitcoin, Sui); transfers, swaps, simulation, and signing on Solana and EVM; EVM allowance checks; Solana-only portfolio rebalancing; Hyperliquid perps; and CASH API payments |
### Rules
Constraints and best practices the agent applies automatically when generating code:
| Rule | Description |
| ----------------------------- | --------------------------------------------------------- |
| `embedded-wallet-constraints` | Constraints and limitations for Phantom embedded wallets |
| `phantom-sdk-best-practices` | General best practices for using Phantom Connect SDKs |
| `solana-transaction-safety` | Safety rules for Solana transaction handling with Phantom |
### MCP servers
Two MCP servers are bundled with the plugin:
| MCP server | Description |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `phantom-connect-sdk` | Gives Cursor real-time access to Phantom developer documentation for accurate answers and code generation |
| `phantom-mcp` | Gives Cursor direct access to Phantom embedded wallet operations: address and balance reads across Solana, EVM, Bitcoin, and Sui; transfers, swaps, simulation, and signing on Solana and EVM; EVM allowance checks; Solana-only portfolio rebalancing; Hyperliquid perps; and CASH API payments. Uses Phantom's device-code authentication flow. |
## Usage examples
Once installed, you can ask Cursor to perform Phantom-related tasks directly:
Scaffold a new project:
```
Create a React app with Phantom Connect that supports Google social login and SOL transfers
```
Add wallet features to an existing project:
```
Add Phantom wallet connection and message signing to my existing React app
```
Execute wallet operations:
```
Get my Phantom wallet addresses across all chains
```
```
Transfer 0.1 SOL to H8FpYTgx4Uy9aF9Nk9fCTqKKFLYQ9KfC6UJhMkMDzCBh
```
Ask documentation questions:
```
How do I verify a domain in Phantom Portal?
```
```
What are the spending limits for embedded wallets?
```
## How it works
The plugin enhances Cursor's AI agent in three ways:
1. Context: The MCP servers give the agent access to Phantom documentation and wallet operations, so it generates accurate code instead of hallucinating APIs.
2. Workflows: Skills provide step-by-step instructions for common integration tasks, ensuring the agent follows the correct setup order and includes all dependencies.
3. Guardrails: Rules enforce SDK best practices and safety constraints automatically, so the agent avoids common mistakes like missing polyfills or unsafe transaction patterns.
## Prerequisites
Install the plugin, then complete the Phantom device-code authentication flow in the browser the first time Cursor performs a wallet action.
If you use the project scaffolding skills to build a separate Phantom app integration, the generated application may still prompt you for project-specific SDK configuration later. That is separate from using the plugin itself.
