## Phantom MCP server

The [Phantom MCP server](/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 13 tools across two capability groups:
