From the project READMEPredictionScan
Derived analytics for researching real-world events with prediction markets.
PredictionScan combines outcome-level buy/sell flow, historical probability changes, large-trade context, public trader research and market-matched news. Eleven read-only tools are available without an API key. Public market data originates from Polymarket; PredictionScan adds aggregation, filtering, ranking and news matching. Independent; not affiliated with or endorsed by Polymarket.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
