微信扫一扫Polymarket MCP — Live Markets & Prices
Access the world's largest prediction market platform directly from your AI assistant.
What is Polymarket?
Polymarket is a decentralized prediction market platform where people trade on the outcomes of real-world events. Market prices represent the crowd's probability estimate for each outcome — making them some of the most accurate real-time forecasts available.
Why this MCP server?
Most tools that access Polymarket use cached API data with stale prices. polymarket-mcp pulls live prices directly from the CLOB v2 order book — the same data traders use — so you always get the most accurate numbers.
APIs used
| API | URL | Purpose |
|---|---|---|
| Gamma API | https://gamma-api.polymarket.com | Market catalogue, search, metadata |
| CLOB v2 | https://clob.polymarket.com | Live order-book midpoint prices, price history |
Smart slug resolution
When you search for markets, you get back event slugs. These same slugs work
directly with get_market_details and get_current_prices — the server
automatically resolves event slugs → most active embedded market, so you
never need to manually look up a separate ID.
search_markets("bitcoin")
→ slug: "when-will-bitcoin-hit-150k"
get_current_prices("when-will-bitcoin-hit-150k") ← works directly
get_market_details("when-will-bitcoin-hit-150k") ← works directly
get_price_history("when-will-bitcoin-hit-150k", "7d") ← works directly
Price history sparklines
get_price_history("will-bitcoin-hit-150k-by-june-30-2026", "24h")
