PolyBridge

Connects Claude to PolyBridge's prediction market intelligence through two read-only tools: polybridge_search for querying market data with optional filters and dimensions, and polybridge_forecast for generating probability forecasts on specific questions. Runs either as a hosted Streamable HTTP endpoint or locally via MCPB with a PolyBridge API key. Useful when you need to pull real-time prediction market signals into your workflow, whether that's researching event probabilities, tracking forecasts across dimensions, or incorporating crowd-sourced intelligence into analysis. The hosted version keeps your API key server-side, while the local MCPB option stores credentials on your machine. Both paths expose the same search:read and forecast:read scopes over stdio or HTTP transport.
