What it is
A Bitcoin-native server for agents: an encrypted local wallet plus a wide tool surface over Bitcoin L1, Lightning, Stacks L2 and the protocols built on them.
Requirements
No account to register — but a wallet with a password you choose, and a mnemonic that is the only recovery path. Keys live under ~/.aibtc/, encrypted with AES-256-GCM and Scrypt, with file permissions set to owner-only; the wallet auto-locks after 15 minutes unless wallet_set_timeout says otherwise. Install with npx @aibtc/mcp-server@latest --install, which has variants for Claude Desktop, Cursor, Windsurf, Gemini CLI, Codex and VS Code. NETWORK chooses mainnet or testnet (mainnet by default) and --testnet on the install command wires up the testnet variant. The bundled bridge can run read-only with individual write tools allowed by name, and prints a safety receipt to stderr — network, read-only status, exposed, write and blocked tool counts, and the session spend cap — before any agent loop begins.
Setup effort
One command — npx @aibtc/mcp-server@latest --install
