Parlay

What is Parlay?

Parlay is a hosted MCP server for searching, comparing, and briefing prediction markets from AI assistants. It is a PMXT-backed aggregator over Polymarket, Kalshi, and Limitless, with Manifold treated separately as a sentiment-only signal. It provides tools that return unified metadata with risk flags and a non-trade-recommendation disclaimer.

For JSON-config clients (Cursor, Cline, Claude Code, etc.), generate a personal access token at https://parlay.run/settings/tokens, export PARLAY_TOKEN, then add the server configuration with streamable HTTP transport. Free tier includes 15 tool calls per month; Pro offers 150 calls for $29/month.
