A unified MCP server for prediction markets. Search and compare across Polymarket, Kalshi, Limitless, and Manifold from inside Claude, ChatGPT, Gemini, OpenClaw, and any MCP-compatible AI client.
Parlay aggregates real-money prediction markets and sentiment markets through one hosted endpoint, with mechanical separation between the two so that real-money analysis never gets contaminated with play-money signal.
| Tool | Purpose | Plan |
|---|---|---|
search_markets | Cross-venue keyword search for live prediction markets and event contracts | Free |
market_brief | Synthesized brief on a topic, combining real-money signals with community sentiment | Free |
discover_markets | Browse trending, high-volume, fast-moving, or high-disagreement markets | Pro |
compare_markets | Compare the same event contract across venues side-by-side — probability, liquidity, settlement | Pro |
scan_discrepancies | Surface cross-venue price discrepancies as a discovery feed (informational, not trade recommendations) | Pro |
inspect_platform | Drill into a single named venue | Pro |
Every tool response carries unified metadata: data freshness, venues queried, venues failed, market type (real_money / sentiment / mixed), match confidence (high / medium / low / not_applicable), liquidity status, risk flags, and a standard non-trade-recommendation disclaimer.
Typical queries Parlay handles well:
MCP URL: https://mcp.parlay.run/mcp
Auth: OAuth
Transport: Streamable HTTP
Parlay connects through Claude's Custom Connectors interface. The same flow works across all Claude surfaces.
https://mcp.parlay.run/mcpParlay's tools will appear in your tool list on the next message.
Note: Custom connectors are available on Free, Pro, Max, Team, and Enterprise plans. Free Claude users are limited to one custom connector at a time. Do not configure Parlay through
claude_desktop_config.json— that file is for local stdio MCP servers only; Parlay is a remote MCP server.
Add https://mcp.parlay.run/mcp to your client's MCP server configuration. The OAuth flow will trigger on first tool call. Refer to your client's MCP setup documentation for the exact configuration file location and remote-MCP support status.
Primary real-money venues: Polymarket, Kalshi
Secondary PMXT-backed venues/sources: Limitless, Opinion.trade, Smarkets, Myriad, Metaculus, Probable, Baozi
Secondary sources may have incomplete pricing, volume, or liquidity data. Parlay flags these cases with metadata such as secondary_venue_data, volume_unconfirmed, and depth_unknown_on_one_platform, so downstream tools and AI agents can treat them with appropriate caution.
Sentiment venues: Manifold — isolated from real-money comparison and discrepancy tools.

compare_markets, scan_discrepancies). The sentiment_market_excluded risk flag is emitted whenever it is filtered out.Parlay's real-money venue access is built on PMXT, an open-source unified SDK for prediction market venues. Parlay adds the AI intelligence layer on top: event comparability, settlement-risk metadata, sentiment isolation, and tool orchestration for MCP. PMXT trading methods are explicitly not exposed by Parlay — the hosted product is read-only by design.
