Overview

AI-generated overview

Gives an assistant live Kalshi and Polymarket prediction-market prices, orderbooks, trades, and results, billed per result through Apify.

What it does
This remote MCP server exposes live prediction-market data from Kalshi and Polymarket, covering prices, orderbooks, trades, and market results. It is hosted by Apify and reached over streamable HTTP, so the assistant queries it directly rather than running anything locally. The manifest lists no tools, so the exact tool names and parameters are not documented here.
When to use it
Use it when an assistant needs current prediction-market or event-contract data from Kalshi or Polymarket, for example to check odds, inspect orderbook depth, review recent trades, or look up settled results. It is not a general market-data source for stocks or crypto.
Requirements
A remote MCP endpoint at mcp.apify.com over streamable HTTP; no local package or runtime is needed. The manifest declares no authentication, environment variables, or headers, but the description says usage is paid per result via Apify, so an Apify account and billing arrangement are likely required.
Before you install
Usage is billed per result through Apify, so queries can cost money and should be scoped carefully. The manifest declares no credentials, but the Apify platform may still require an account or token before the endpoint works. Data is fetched from third-party sources (Kalshi and Polymarket) and passed through Apify.
