Signal-first Bitcoin intelligence over MCP. Surfaces leading, non-price indicators — sovereign reserve adoption, Bitcoin/crypto-infra hiring velocity, and network hashrate trend — each with a 0–100 strength, a direction (tailwind/headwind/neutral), a one-line rationale, and primary sources. Tools: scan_signals, get_hiring_signal, get_sovereign_reserves, get_network_signal, get_daily_brew. Resource: coinbucha://methodology. Information, not financial advice.

GoodQuote is a price-agreement layer for the agent economy. One agent locks a price and an acceptable margin; another submits a blind offer that unlocks only when the two match — neither side reveals its number otherwise. Stateless and private: no accounts, no database, deals auto-erase. Connect over one URL with five tools.
