A Bitcoin transaction signing server that enables AI assistants to generate Bitcoin addresses and sign transactions through the MCP protocol. Built by Cerebro Foundation, this implementation provides two key tools: one for generating P2WPKH addresses from private keys in WIF format, and another for signing partially signed Bitcoin transactions (PSBTs). The server uses the @scure/btc-signer library along with secp256k1 cryptography to securely handle Bitcoin operations, making it useful for cryptocurrency wallet integrations and transaction signing workflows, though the authors note it's intended as a play project rather than for production use.
