The Phantom MCP Server (@phantom/mcp-server) is a Phantom wallet product for users who interact through AI agents. Just like the mobile wallet and browser extension serve users who click and tap, the MCP server serves users who interact through natural language with their AI assistant. When someone uses Claude, Cursor, or another AI agent and asks “send 10 USDC to my friend” or “swap some SOL for ETH,” Phantom’s MCP server is the wallet the agent uses to act on their behalf.
The Phantom MCP Server is currently in preview and may change at any time. Always use a separate Phantom account for testing. Never use accounts containing significant assets.

​
What are you here for?

Set up the MCP server

Add the Phantom MCP Server to Claude Desktop, Cursor, or Claude Code and get a wallet for your AI agent.

​
Quick install

You need an App ID from Phantom Portal before getting started. Then add this config to your AI client: 
{
  "mcpServers": {
    "phantom": {
      "command": "npx",
      "args": ["-y", "@phantom/mcp-server"],
      "env": {
        "PHANTOM_APP_ID": "your_app_id_from_portal"
      }
    }
  }
}
See the setup guide for step-by-step instructions for Claude Desktop, Cursor, and Claude Code.
