Give your AI agent a crypto wallet. Sign messages, send transactions, transfer tokens, and swap across Solana and EVM chains using Phantom's non-custodial wallet.
Give your agent a wallet. Swap, sign, and manage addresses across Phantom's supported chains — and tap into Phantom's docs for context. This plugin also includes skills, rules, and agents to help scaffold wallet-connected apps with the Phantom Connect SDK across React, React Native, and vanilla JS/TS.
Works with both Cursor and Claude Code.
.cursor-plugin/plugin.json manifest.phantom-connect-sdk and phantom-mcp) will appear in your MCP settings.Install the plugin from a marketplace, or load it locally for development:
# From a marketplace (if available)
claude plugin install phantom-connect@marketplace-name
# From a local directory
claude --plugin-dir /path/to/phantom-connect-plugin/
Claude Code will detect the .claude-plugin/plugin.json manifest and load all skills, agents, and MCP servers.
Use the /phantom-connect:phantom-connect skill to get full SDK assistance:
/phantom-connect:phantom-connect react # React SDK help
/phantom-connect:phantom-connect browser # Browser SDK help
/phantom-connect:phantom-connect react-native # React Native SDK help
All 8 skills are shared between Cursor and Claude Code, auto-discovered from skills/.
| Skill | Description |
|---|---|
| phantom-connect | Comprehensive skill covering all three SDKs, transactions, payments, token-gating, and NFT minting |
| setup-react-app | Scaffold a React app with @phantom/react-sdk, PhantomProvider, ConnectButton, and hooks |
| setup-browser-app | Scaffold a vanilla JS/TS app with @phantom/browser-sdk singleton pattern |
| setup-react-native-app | Scaffold a React Native (Expo) app with @phantom/react-native-sdk and required polyfills |
| send-sol-transaction | Build and send SOL transfers with proper signing and verification |
| sign-message | Implement message signing for Solana and EVM, including SIWS authentication |
| add-social-login | Configure Google/Apple social login with embedded wallet support |
| phantom-wallet-mcp | Execute wallet operations via the Phantom MCP — addresses, transfers, signing, swaps |
| Rule | What It Enforces |
|---|---|
| phantom-sdk-best-practices | Use signAndSendTransaction, proper provider setup, error handling, connection checks |
| solana-transaction-safety | Use LAMPORTS_PER_SOL, verify transactions, correct network selection, no key exposure |
| embedded-wallet-constraints | No signTransaction, spending limits, session duration, polyfill requirements |
Claude Code's plugin system does not support always-on rules. These rules are embedded in the
phantom-connectskill and applied when the skill is invoked.
| Agent | Purpose |
|---|---|
| Phantom Integration Specialist | SDK integration — scaffolds projects, writes correct code, validates against constraints, and looks up Phantom docs in real-time |
| Phantom Wallet Agent | Wallet operations — get addresses, transfer tokens, sign transactions, execute swaps, and sign messages via the phantom-mcp server |
| Server | Transport | Description |
|---|---|---|
| phantom-connect-sdk | SSE | Phantom Connect SDK documentation at https://docs.phantom.com/mcp for real-time API reference |
| phantom-mcp | stdio | Wallet operations via @phantom/mcp-server — sign transactions, transfer tokens, buy tokens, sign messages |
The phantom-mcp server requires a PHANTOM_APP_ID environment variable from Phantom Portal. Set it in your environment or MCP settings.
Once installed, ask the agent to:
The agent will follow the plugin's skills and rules to generate correct, safe integration code.
