AI agents

App users

Build apps with Phantom Connect SDKs. Integrate embedded wallets and social login into your web or mobile app.

​
Phantom MCP Server

The Phantom MCP Server gives AI agents a Phantom wallet. It’s a core Phantom product — like the mobile app and browser extension, but for users who interact with crypto through AI agents. Agents can trade, transfer, and manage assets across Solana, Ethereum, Bitcoin, and Sui using 25 tools across three capability groups:

Wallet operations

View addresses and balances, send transactions, sign messages on Solana and EVM chains

Swaps and portfolio

Swap tokens on Solana and EVM, cross-chain swaps, and portfolio rebalancing

Hyperliquid perps

Deposit, open and close positions, manage orders and leverage on Hyperliquid

Set up the MCP server

Add the Phantom MCP Server to Claude Desktop, Cursor, or Claude Code
