Phantom Wallet MCP

Use the phantom MCP server to interact with the user's Phantom wallet directly — no SDK integration code needed.

Setup

Add the Phantom MCP server to your MCP configuration:

{
  "mcpServers": {
    "phantom": {
      "command": "npx",
      "args": ["-y", "@phantom/mcp-server"],
      "env": {
        "PHANTOM_APP_ID": "<your-app-id>"
      }
    }
  }
}

Get your PHANTOM_APP_ID from Phantom Portal. On first use, the server opens a browser for OAuth authentication via Google or Apple login.

Available Tools

Supported Networks

Examples

Get wallet addresses

Retrieve the user's wallet addresses across all supported chains:

Use the phantom MCP's get_wallet_addresses tool to list the user's addresses.

Returns addresses for each connected chain (Solana, Ethereum, Bitcoin, Sui).

Transfer SOL

Send SOL to a recipient address:

Use the phantom MCP's transfer_tokens tool:
- token: "SOL"
- recipientAddress: "<recipient>"
- amount: "0.1"
- network: "solana:mainnet"

The MCP handles transaction building, signing, and submission.

Transfer SPL tokens

Send any SPL token by its mint address:

Use the phantom MCP's transfer_tokens tool:
- token: "<token-mint-address>"
- recipientAddress: "<recipient>"
- amount: "10"
- network: "solana:mainnet"

Buy / swap tokens

Get a swap quote and optionally execute it:

Use the phantom MCP's buy_token tool:
- tokenMint: "<token-mint-to-buy>"
- amount: "1000000"  (in lamports for SOL input)
- network: "solana:mainnet"

Sign a message

Sign a UTF-8 message for verification or authentication:

Use the phantom MCP's sign_message tool:
- message: "Hello, verifying ownership"
- network: "solana:mainnet"

The MCP routes to the correct chain-specific signing based on the network parameter.

Important Notes

• Preview software — use a separate wallet with minimal funds for testing
• Sessions persist locally in ~/.phantom-mcp/session.json
• The MCP server runs via stdio transport (launched by npx -y @phantom/mcp-server)
• Token transfers on Solana support both native SOL and any SPL token
• Swap quotes come from Phantom's API and include fee and slippage info
