Overview

AI-generated overview

Local MCP server giving an assistant real-time Polymarket and Kalshi prediction-market data, cross-platform arbitrage detection and strategy signals.

What you can do
  • Retrieve real-time market data from Polymarket and Kalshi.
  • Compare markets across the two platforms to detect arbitrage opportunities.
  • Surface strategy signals derived from that market data.
  • No individual tools are documented, so the exact operations are not listed.
When to use it
Useful when you want an assistant to look up prediction-market prices and odds, compare the same event across Polymarket and Kalshi, or flag possible arbitrage and trading signals while researching or monitoring markets.
Requirements
Runs as a local stdio process (npm package prediction-market-mcp), so Node.js and a desktop MCP client are needed. Requires a RapidAPI key supplied through the RAPIDAPI_KEY environment variable; the key is obtained from the Prediction Market Data API listing on RapidAPI. Network access is needed for the upstream API.
Before you install
You must supply a third-party RapidAPI key, and all market queries go through that external API provider. The server reports arbitrage and strategy signals, which are informational and not investment advice; any trading decisions and money are outside this server. No tools are documented, so review what it can actually call before installing.

Installation

In SourceWeft

  1. Open Prediction Market Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
