PolyBridge MCP Server tools

2

Search public prediction markets for markets relevant to a natural-language topic or question. Use when you need candidate markets, market URLs, outcomes, statuses, and relevance scores. Do not use for a final probability forecast, market-history lookup, trading, or private/internal data. Scores are relevance scores, not probabilities.

Generate a read-only probability forecast for a clearly stated future event by searching relevant prediction markets and synthesizing evidence. Use when the user asks for a probability, outlook, or forecast; use polybridge_search when they only need market discovery. Does not place trades, provide financial advice, or access private/internal data.

Overview

What is PolyBridge MCP?

PolyBridge MCP gives AI clients probabilistic foresight from live prediction markets. It allows users to ask questions about the future — even when no exact market exists — by finding relevant markets, synthesizing the evidence, and returning a read-only forecast with probabilities and source-market metadata. It is intended for AI agents or applications that need market-derived probability estimates without executing any trades.

How to use PolyBridge MCP?

Connect your MCP client to the hosted endpoint at https://mcp.polybridge.ai/mcp and invoke the provided tools: polybridge_search to find relevant prediction markets and polybridge_forecast to estimate probabilities from market evidence. No API key is required at anonymous usage limits; add a key or OAuth for higher usage.

  • Synthesizes evidence even when no exact market exists.
