Scored across 6 tools
Each tool addresses a distinct function: market listing, market details, order details, portfolio overview, and two order types with clear differences. No overlaps.
All tools follow a consistent verbNoun camelCase pattern (getAllMarkets, getMarketDetails, getOrder, getPortfolio, placeLimitOrder, placeMarketOrder).
Six tools cover the essential operations for a prediction market server—browsing, querying, portfolio, and trading—without being excessive or insufficient.
Core functionalities are present, but missing order cancellation and trade history, which are common in trading APIs. Minor gap.
