Phantom MCP server

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.

Agent wallets and your existing accounts

Why your agent gets a new wallet when you sign in, and how to access your existing Phantom accounts.

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.

Use it with OpenClaw

Install the Phantom OpenClaw plugin to bring the same Phantom wallet capabilities directly into OpenClaw.

Quick install

No App ID or Phantom Portal setup required. Add this config to your AI client:

{
  "mcpServers": {
    "phantom": {
      "command": "npx",
      "args": ["-y", "@phantom/mcp-server@latest"]
    }
  }
}

On first use, a browser window opens for device-code sign-in. See the setup guide for step-by-step instructions for Claude Desktop, Cursor, and Claude Code.

Agents receive a new dedicated wallet on authentication — not your existing personal wallet. You must fund the agent’s wallet before it can transact. Use get_wallet_addresses to find the address after setup.

What agents can do

The MCP server gives agents wallet, swap, and perp-trading tools. See the setup guide and tool reference for full parameter documentation.

No fees on swaps. All swaps executed through buy_token and portfolio_rebalance are fee-free.

How agent wallets sign

Agent wallets complete a Phantom Connect sign-in, then use an OIDC stamper to stamp KMS requests. KMS validates the stamp, enforces policy, and then signs and submits.
