Parlay tools (6)

write = sends, deletes, buys or posts
  • compare_marketsFree

    Compare the same event contract across Polymarket, Kalshi, and Limitless side-by-side: probability, liquidity, settlement rules, and venue type. Use when the user wants to know "what's the spread between Polymarket and Kalshi on X" or "which venue has better liquidity for Y". Returns match confidence buckets (high/medium/low) and explains any mismatches. Real-money venues only — Manifold is excluded because play-money pricing isn't comparable to real-money.

  • discover_marketsFree

    Browse trending, high-volume, fast-moving, or high-disagreement prediction markets across Polymarket, Kalshi, Limitless, and Manifold. Use when the user wants to explore what's happening — "what's hot on Polymarket today", "show me biggest political markets", "what events are ending soon" — rather than search a specific topic. Filter by category and sort by volume, newest, or ending soon.

  • inspect_platformFree

    Inspect a single named venue. Returns available capabilities, market data for the query, and metadata quality flags. Use when the user explicitly names a venue — "show me Polymarket markets on AI", "what's on Kalshi for Q4 inflation", "Manifold markets about geopolitics". For cross-venue queries use `search_markets` or `compare_markets`.

  • market_briefFree

    Generate a synthesized brief for a topic, combining real-money signals from Polymarket, Kalshi, and Limitless with Manifold community sentiment. Use for analytical queries like "what do markets think about the 2028 election", "odds on a Fed rate cut", or "how is crypto priced for year-end". Returns top markets by volume, cross-venue divergences, venue coverage, and risk flags. For raw market lists use `search_markets`.

  • scan_discrepanciesFree

    Surface cross-venue price discrepancies between Polymarket, Kalshi, and Limitless as a discovery feed for price discovery and divergence detection. Default threshold is 0.5% spread, below typical round-trip fees — most results are informational, not tradable arbitrage. Raise `min_spread` to 0.03+ for after-fee opportunities. The optional `query` parameter post-filters results by topic keywords on event titles — it does not perform a topic search; for topic-driven retrieval use `discover_markets` or `search_markets`. Pairs with missing volume data on at least one venue are flagged 'volume_unconfirmed'. All results are indicative only — not trade recommendations. Real-money venues only. Orderbook depth is not confirmed in Phase 1.

  • search_marketsFree

    Search live prediction markets and event contracts across Polymarket, Kalshi, Limitless (real-money) and Manifold (sentiment). Use for queries on election odds, political markets, Fed rate decisions, crypto prices, sports outcomes, geopolitics, and other binary markets with crowd-sourced probabilities. Returns unified results with title, current probability, volume, liquidity, expiration, source venue, and risk flags. For topic synthesis use `market_brief`; for browsing trending markets use `discover_markets`.

Parlay — Prediction Market MCP Server

The AI-native intelligence layer for prediction markets.

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. This repository is the public bundle and connection reference for the hosted Parlay service at https://mcp.parlay.run/mcp; it does not contain the MCP server implementation.

What it does

Every tool response carries unified metadata: data freshness, venues queried, venues failed, market type (realmoney / sentiment / mixed), match confidence (high / medium / low / notapplicable), liquidity status, risk flags, and a standard non-trade-recommendation disclaimer.

Connect

Parlay supports two connection paths depending on your client.

Path A — Claude.ai (Desktop, web, mobile, Cowork)

Parlay connects through Claude's Custom Connectors interface. The same flow works across all Claude surfaces.

  1. Open Claude settings (profile icon → Settings).
  2. In the sidebar, select Connectors.
  3. Scroll to the bottom and click Add custom connector.
  4. Enter URL: https://mcp.parlay.run/mcp
  5. Click Add, then Connect to complete OAuth authorization.

Parlay'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 claudedesktopconfig.json — that file is for local stdio MCP servers only; Parlay is a remote MCP server.

Path B — OpenClaw, Cursor, Cline, Claude Code, LobeHub, and other JSON-config clients

These clients read MCP server configuration from a JSON file and don't run an OAuth dance themselves. Use a personal access token instead.

  1. Generate a token at https://parlay.run/settings/tokens
  2. Export it: export PARLAYTOKEN=parlaypat_xxxxxxxxxxxx

Security: Treat your token as a secret. Do not share, log, or commit it. Store it only in your local MCP client configuration.

Cline

Recommended: Use Cline's Remote Servers tab → "Add Server", entering https://mcp.parlay.run/mcp as the URL, selecting Streamable HTTP as the Transport Type, and adding Authorization: Bearer as a header.

For manual JSON editing or detailed troubleshooting, see llms-install.md. Do not copy .mcp.json verbatim into Cline — Cline uses a slightly different schema (covered in the install guide).

OpenClaw

git clone https://github.com/parlay-run/parlay-mcp.git
openclaw plugins install ./parlay-mcp
openclaw gateway restart

Cursor / Claude Code

Drop the parlay entry from .mcp.json (at the root of this repo) into your client's MCP server config.

{
  "mcpServers": {
    "parlay": {
      "url": "https://mcp.parlay.run/mcp",
