WHAT IT DOES

What bap_friend does on Bitcoin SV MCP Server

AI agents invoke bap_friend to trigger actions in Bitcoin SV MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why bap_friend is rated High

This tool broadcasts a transaction to the BSV blockchain, which is an irreversible on-chain action. While not financial or destructive in the traditional sense, it executes an external blockchain operation with permanent effects. Broadcasting transactions cannot be undone once confirmed on-chain, making this an Execute-category action with high severity due to the permanent, public nature of blockchain writes.
