AIBTC Bitcoin Wallet
A skill for managing Bitcoin L1 wallets with optional Pillar smart wallet and Stacks L2 DeFi capabilities.
Install
One-command installation:
npx @aibtc/mcp-server@latest --install
For testnet:
npx @aibtc/mcp-server@latest --install --testnet
Quick Start
Check Balance
Get your Bitcoin balance:
"What's my BTC balance?"
Uses get_btc_balance - returns total, confirmed, and unconfirmed balances.
Check Fees
Get current network fee estimates:
"What are the current Bitcoin fees?"
Uses get_btc_fees - returns fast (~10 min), medium (~30 min), and slow (~1 hr) rates in sat/vB.
Send BTC
Transfer Bitcoin to an address:
"Send 50000 sats to bc1q..."
"Transfer 0.001 BTC with fast fees to bc1q..."
Uses transfer_btc - requires an unlocked wallet.
Wallet Setup
Before sending transactions, set up a wallet:
- Create new wallet:
wallet_create - generates encrypted BIP39 mnemonic
- Import existing:
wallet_import - import from mnemonic phrase
- Unlock for use:
wallet_unlock - required before transactions
Wallets are stored encrypted at ~/.aibtc/.

Troubleshooting
"Wallet not unlocked"
Run wallet_unlock with your password before sending transactions.
"Insufficient balance"
Check get_btc_balance - you need enough BTC for amount + fees.
"Invalid address"
Ensure address matches network:
- Mainnet: starts with
bc1
- Testnet: starts with
tb1
