Agent Wallet MCP

Give Claude a Solana wallet.

An MCP (Model Context Protocol) server that lets Claude send USDC, check balances, and manage transactions on Solana.

Demo

You: "What's my wallet balance?" Claude: Let me check your wallet balance. { "sol": 1.5, "usdc": 25.00, "network": "devnet", "address": "7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU" } You: "Send $5 USDC to [address] for the API calls I just used" Claude: I'll send 5 USDC to that address now. { "success": true, "signature": "5UfgJ3...", "recipient": "...", "amount": 5, "explorer": "https://explorer.solana.com/tx/..." } Done! Transaction confirmed on Solana devnet.

Installation

# Clone the repo git clone https://github.com/noah-ing/agent-wallet-mcp.git cd agent-wallet-mcp # Install dependencies npm install # Build npm run build

Setup with Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{ "mcpServers": { "agent-wallet": { "command": "node", "args": ["/path/to/agent-wallet-mcp/dist/index.js"] } } }

Then restart Claude Desktop.

Available Tools

Description

get_wallet_address

get_recent_transactions

request_devnet_airdrop

How It Works

  1. Persistent Wallet: Creates a keypair stored at ~/.agent-wallet/keypair.json

  2. Devnet Only: All transactions happen on Solana devnet (test network)

  3. Real Transactions: These are actual blockchain transactions, just on testnet

Getting Devnet USDC

The wallet starts empty. To test sending USDC:

  1. Get your wallet address: Ask Claude "What's my wallet address?"

  2. Get devnet SOL: Ask Claude "Request a devnet airdrop"

  3. Get devnet USDC from Circle's faucet or Solana faucet

Development

# Watch mode npm run dev # Test with MCP Inspector npm run inspector

Why This Exists

AI agents will eventually need to pay for things - API calls, compute, services from other agents.

This is a simple demo of what that looks like: Claude with a wallet, making real (testnet) transactions.

Security Notes

  • Devnet only - No real money involved

  • Local keypair - Private key never leaves your machine

  • No mainnet support - Intentionally limited to devnet for safety
