✅ Implemented Tools

MetaMask / EVM Wallets (Read-Only)

// Connect wallet address for monitoring
wallet_connect_address({ address: "0x..." })

// Get balances (ETH + tokens)
wallet_balance({ address?: string, chain?: string, allChains?: boolean })

// Get token holdings
wallet_tokens({ address?: string, chain?: string })

// Get recent transactions
wallet_transactions({ address?: string, chain?: string, limit?: number })

// Get gas prices
wallet_gas({ chain?: string })

Supported Chains:

• Ethereum Mainnet
• Polygon
• Arbitrum One
• Optimism
• BNB Smart Chain
• Avalanche C-Chain
• Base

Electrum / Bitcoin

// Connect to Electrum RPC
electrum_connect({ host?: string, port?: number })

// Get BTC balance
electrum_balance()

// Get transaction history
electrum_history({ limit?: number })

// Get addresses
electrum_addresses()

// Generate new address
electrum_new_address({ label?: string })

// Create transaction (requires confirmation in Electrum)
electrum_send({ destination: string, amount: string, feeRate?: number })

Prerequisites for Electrum:

# Start Electrum daemon
electrum daemon -d

# Enable RPC (default port 7777)
electrum setconfig rpcport 7777

Example Usage

Monitor ETH Wallet

K.I.T., track wallet 0x1234...abcd

📊 Wallet: 0x1234...abcd

🔗 Ethereum:
   2.5432 ETH
   1,000.00 USDC
   500.00 LINK

🔗 Polygon:
   1,234.56 MATIC
   5,000.00 USDC

Check Gas Prices

K.I.T., what are gas prices on Ethereum?

⛽ Gas Prices (Ethereum)

Current: 25.50 gwei
Base Fee: 24.00 gwei
Priority Fee: 1.50 gwei

📊 Estimated Costs:
   Transfer: 0.000535 ETH
   Swap: 0.003825 ETH
   NFT Mint: 0.002550 ETH

Bitcoin Balance

K.I.T., check my Bitcoin balance

₿ Bitcoin Wallet Balance

Confirmed: 0.15000000 BTC
Unconfirmed: 0.00500000 BTC

💰 Total: 0.15500000 BTC
📍 Addresses: 12

Security Model

✅ Read-Only by Default

• K.I.T. can VIEW balances without transfer permission
• Uses public RPCs (no API keys needed for EVM)
• No private keys stored or transmitted

⚠️ Transaction Safety

• Bitcoin sends require confirmation in Electrum GUI
• EVM transactions not implemented (use hardware wallet)
• User retains full control at all times

🔒 Security Features

• Address validation (checksum)
• Local RPC only for Electrum
• No external API key requirements for basic use
• Cached balances (30s) to reduce RPC calls
